The special high temperature plastic package will withstand
the temperatures associated with Infra-red or vapour phase
reflow soldering processes. A flexible inner encapsulant protects
the sensitive glass/metal reed switch seals - this is a very big
advantage over the more usual hard moulded package.

volt operating coils. The 1 Form A, 1kV version has
a package and pin configuration compatible with
the standard 109P type, i.e. 4 pins on 0.15 inches
(3.8mm) pitch. These can be stacked side-by-side
for maximum packing density. The other types have
package lengths and pin configurations appropriate
for their voltage ratings and the user will need to
arrange suitable clearance distances around the
parts.

The Pickering Series 119 is a new range of very
small Single-in-Line Reed Relays intended for
voltages very much higher than standard small SIL
relays. The vacuumed, sputtered ruthenium reed
switches have a superb low level performance also,
which makes them an ideal choice where a wide
range of signals are involved.

Notes
Note 1, Switching Voltage
This high voltage rating is for RESISTIVE loads only. At these high voltages, even
stray capacitance can generate very high current pulses, which can damage the
contact plating causing welding of the reed switch. If there is capacitance in
circuit, provision should be made to limit the surge, to within the current and
power ratings of the relay.
2UGHU&RGH
Note 2, Life expectancy
The life of a reed relay depends upon the switch load and the end of life
criteria. As an example, with an ‘end of life’ contact resistance specification of
1 ohm, switching low loads (10 V at 10mA resistive) or when ‘cold’ switching,
typical life will be around 1000 Million operations. At the maximum load
(resistive), typical life will be 10 Million operations. In the event of abusive
conditions, for example high currents due to capacitive inrushes, this figure will
reduce considerably. Pickering will be pleased to perform life testing with any
particular load condition.

Due to the asymmetrical internal construction of the relay, the
capacitance to the coil from one switch connection is approximately
half the capacitance of the other switch connection, pin 3 is lower. In
some applications this feature may be used to advantage for example,
in a multiplexer where it is desirable to minimize the capacitance of
the common connection to maximize bandwidth.

The Pickering Series 117 is a range of Single-in-Line relays
intended for very high density applications such as A.T.E.
switching matrices or multiplexers.
Single switch versions require a board area of only 0.15 inches
x 0.27 inches. This is one quarter of the board area of the
industry standard 0.2 x 0.8 inches Single-in-Line packge.
The very small size of these relays often makes it possible to
increase the functionality of existing designs without increasing
the size of printed circuit boards.
The Series 117 switch rating of 3 Watts, 0.25 A. is adequate
for most instrumentation applications. If a higher rating
is required, the Series 116, which is rated at 10 Watts,
0.5 A. should be considered. The relay footprint and pin
configurations of the Series 116 are identical but the case
height increases slightly to 0.49 inches. (12.5 mm.)
The relays feature an internal mu-metal magnetic screen.
Mu-metal has the advantage of a high permeability and low
magnetic remanence and eliminates problems that would
otherwise occur due to magnetic interaction. Interaction is
usually measured as a percentage increase in the voltage
required to operate a relay when additional relays, stacked
each side, are themselves operated. An unscreened device
mounted on this pitch would have an interaction figure of
around 40 percent. Relays of this size without magnetic
screening would therefore be totally unsuitable for applications
where dense packing is required.
3 volt and 5 volt coils are available with an optional Back
E.M.F suppression diode.

The reed switch in the Series 116 is suitable for low level or 'cold'
switching. In accordance with Pickering convention, this switch is referred
to as type number 2. There is no general purpose switch (type number 1)
currently available in this series, but the type 2 is suitable for all applications
if it is used within its specified ratings.

Notes
Note 1, Life expectancy
The life of a reed relay depends upon the switch load and the end of life
criteria. As an example, with an 'end of life' contact resistance specification
of 1 ohm, switching low loads (10 V at 10mA resistive) or when 'cold'
switching, typical life will be around 250 Million operations. At the
maximum load (resistive), typical life will be 10 Million operations. In the
event of abusive conditions, for example high currents due to capacitive
inrushes, this figure will reduce considerably. Pickering will be pleased to
perform life testing with any particular load condition.
Note 2, Switch to coil capacitance
Due to the asymmetrical internal construction of the relay, the capacitance
to the coil from one switch connection is approximately half the capacitance
of the other switch connection, pin 3 is lower. In some applications this
feature may be used to advantage for example, in a multiplexer where
it is desirable to minimize the capacitance of the common connection to
maximize bandwidth.
The Series 116 relays are fitted with an internal mu-metal
magnetic screen which permits side-by-side stacking on 0.15
inches pitch. For maximum efficiency of this screen, relays used
in this way should all be mounted the same way round and
with the coil supply of the same polarity.

Two switch types are available. Both types have sputtered
ruthenium contacts for long life and high reliability.
Switch type number 1 is better suited for general purpose
applications. It has a layer of copper beneath the ruthenium
to help dissipate the heat from the contact area. This gives an
improved current inrush handling ability.

Switch type number 2 should be chosen for low level or

The relays require a board area of only 0.15 inches x 0.27
inches. This is one quarter of the board area of the industry
standard 0.2 x 0.8 inches Single-in-Line packge. The very
small size of these relays often makes it possible to increase
the functionality of existing designs without increasing the
size of printed circuit boards.
The relays feature an internal mu-metal magnetic screen.
Mu-metal has the advantage of a high permeability and low
magnetic remanence and eliminates problems that would
otherwise occur due to magnetic interaction. Relays of this
size without magnetic screening would be totally unsuitable
for applications where dense packing is required.
3 volt, 5 volt or 12 volt coils are available. An internal Back
E.M.F suppression diode is available as an option.

l 100% tested for dynamic contact resistance
The Series 114 is a range of Single-In-Line reed
relays intended for power levels that are beyond the
capabilities of conventional dry SIL reed relays.
The more usual dry relays are rated at 0.5 amps at 10
Watts. The Series 114 have a rating of 1 amp switching
at up to 40 watts and will carry 2 amps. In many cases,
this higher rating will allow them to be used as an
alternative to mercury wetted reed relays.
Unusually for high power relays, they feature sputtered
ruthenium contacts instead of the more common
electroplated rhodium or tungsten types. This makes
them suitable for low level or “dry” switching also.
They are able to switch a.c. mains voltages so are
suitable for interfacing to larger electromechanical relays
or contactors. It is important however, to surpress back
EMFs from inductive loads. This is achievable by using
an RC snubber, varistor or similar voltage limiting device.
One or two Form A (energize to make) or One Form B
(energize to break) configurations are available.
The range features an internal mu-metal screen
to minimize problems that would otherwise be
experienced due to magnetic interaction when they are
closely stacked.

l High insulation resistance - greater than 1012

l 100% tested for dynamic contact resistance
These relays require less than half the board area of the
more usual 0.2 x 0.8 inch devices and have a height of
only 0.26 inches (6.6mm.) for the 1 Form A and 1 Form C
types and 0.35 inches (8.9 mm.) for the 2 Form A type.
The Series 113 is encapsulated in a plastic package
using a very high resistivity resin to achieve an insulation
resistance greater than 1012 ohms for the Form A types.
The relay has an internal mu-metal screen which totally
eliminates the risk of magnetic interaction problems. An
unscreened device mounted on this pitch would have
an interaction figure of around 40 percent. Relays of
this size without magnetic screening would therefore be
totally unsuitable for applications where dense packing
is required. Pickering Series 113 have a typical interaction
figure of 5 percent.
3, 5 and 12 Volt coils are standard, with the option of an
internal diode. 1 Form A, 5 Volt coils have a resistance of
500 ohms and may be driven directly from TTL logic.

The standard 1 Form A device has 4 pins on 0.1 inches (2.54mm) pitch (see
drawing above). This configuration makes it pin compatible with the Pickering
Series 110, 111 and 112. A special pin configuration is also available with a
pinout compatible with that of the 2 Form A type (see drawing above) The
switch terminals are pins 1&6, the coil is Pins3&4 with pins 2&5 omitted, this
version has the prefix 113SP. It is sometimes desirable to have a PCB that can
be used for either 1 Form A or 2 Form A switching, this arrangement allows
the use of a common board fitted with the appropriate relay.

The Pickering Series 112 is a range of magnetically
screened single-in-line reed relays that require a board
area of only 0.15 inches (3.8mm.) by 0.4 inches (10mm.)
while retaining the 10 Watts, 0.5 Amps rating associated
with larger relays. This small footprint is achieved by
mounting the reed switch diagonally within the package.
These relays require around one third the board area of
the more usual 0.2 x 0.8 inch devices and the height of
only 0.43 inches (11mm.) is suitable for high density card
based systems such as VME, VXI, Compact PCI, and PXI.
The high quality, sputtered ruthenium switch contacts also
makes them ideal for Automatic Test Equipment.
The Series 112 is encapsulated in a plastic package
using a very high resistivity resin to achieve an insulation
resistance greater than 1012 ohms. The relay has an
internal mumetal screen which totally eliminates the risk
of magnetic interaction problems. An unscreened device
mounted on this pitch would have an interaction figure of
around 40 percent. Relays of this size without magnetic
screening would therefore be totally unsuitable for
applications where dense packing is required. Pickering
Series 112 have a typical interaction figure of 5 percent.
3, 5 and 12 Volt coils are standard, with the option of an
internal diode. 5 Volt coils have a resistance of 500 ohms
and may be driven directly from TTL logic.

The Pickering Series 111 is a range of magnetically screened
single-in-line reed relays that stack on 0.15 inches by 0.4
inches pitch. They have an identical footprint to the Series
110 and 112 but the height is reduced to only 0.26 inches
(6.6mm). The switch rating of 3 Watts is adequate for most
instrumentation applications. If a higher power rating is
required, please look at our Series 110 or 112 which have
a 10 Watts rating and an identical pin-out. The range also
includes the type 111RF, a 50 ohms coaxial device suitable
for use up to 1.5GHz.
These relays require around one third the board area of
the more usual 0.2 x 0.8 inch devices and are ideal for high
density applications.
Two package styles are available:
The type 111 is encapsulated in a mu-metal can. The
coaxial version, type 111RF, is also available in this
package style.

The type 111P is encapsulated in a plastic package and

an option in both types.
Magnetic screening is essential to avoid magnetic interaction
problems. Interaction is usually measured as a percentage
increase in the voltage required to operate a relay when
two additional relays, stacked one each side, are themselves
operated. An unscreened device mounted on this pitch would
have an interaction figure of around 40 %. Relays of this
size would therefore be totally unsuitable for applications
where dense packing is required. Pickering Series 111 have an
interaction figure of around 1 percent.

The Pickering Series 110 V-SIL (vertical single-in-line) is a
range of magnetically screened single-in-line reed relays that
stack on 0.15 inches by 0.4 inches pitch. The switches in this
range are mounted vertically within the package, this allows
the use of the same switch types as would normally be found
in relays requiring a very much larger board area. In this way,
a 10 Watt switch power rating is achieved. Two types of Form
A (energize to make) switches are available, a general purpose
version and a type suitable for low level or “cold” switching
applications.
These relays require around one third the board area of
the more usual 0.2 x 0.8 inch devices. These are your idea
choice for high density applications such as A.T.E. switching
matrices or where very little board area is available. If a lower
profile device is required, look at the Series 111, which has an
identical pin-out but a height of only 0.26 inches.
The Series 110 is encapsulated in a plastic package using a
very high resistivity resin. The relay has an internal mumetal
screen which totally eliminates the risk of magnetic interaction
problems. An unscreened device mounted on this pitch would
have an interaction figure of around 40 percent. Relays of this
size without magnetic screening would therefore be totally
unsuitable for applications where dense packing is required.
Pickering Series 110 have a typical interaction figure of 5
percent.
3, 5 and 12 Volt coils are standard, with the option of an
internal diode. 5 Volt coils have a resistance of 500 ohms and
may be driven directly from TTL logic.

The mu-metal packaged Series 109 and 109RF and the plastic
packaged Series 109P and Series 109PH, are magnetically
screened single-in-line reed relays that stack on 0.15 inches x
0.6 inches pitch. The adjacent column gives further details of the
device types available.
These relays require little more than half the board area of the
more usual 0.2 x 0.8 inch devices, this allows around 80 percent
more relays onto your board. These are the ideal choice for high
density applications such as A.T.E. switching matrices or where
very little board area is available.
Mu-metal, due to its high permeability and low magnetic
remanance is used to provide magnetic screening. This eliminates
problems that would otherwise occur due to magnetic interaction.
Interaction is usually measured as a percentage increase in the
voltage required to operate a relay when two additional relays,
stacked one each side, are themselves operated. An unscreened
device mounted on this pitch would have an interaction figure of
around 40 percent. Relays of this size without magnetic screening
would therefore be totally unsuitable for applications where
dense packing is required. Pickering Series 109 and 109RF have
a typical interaction figure of 1 percent. Series 109P and 109PH
have a typical figure of 3 percent.
Two types of Form A (energize to make) switches are available,
a general purpose switch (switch no.1) and a vacuum sputtered
ruthenium switch (switch no.2) which is ideal for low level
or “cold” switching applications. 5 volt coils normally have a
resistance of 500 ohms and 12 volt coils are 1000 ohms. A
sensitive single pole 5 volt device with a 1000 ohms coil is also
available. Internal back E.M.F. clamping diodes are an option for
all types. The small size of these relays often makes it possible to
increase the functionality of existing designs without increasing
the size of printed circuit boards.
Description of Device Types
See reverse side of data sheet for dimensional details.
Series 109 1 Form A, 2 Form A, 1 Form B, 1 Form C
Similar in construction to the Pickering Series 107 and
Series 108. These patented devices are encapsulated in
mu-metal cans using very high resistivity resins.
Series 109RF Coaxial 1 Form A
Coaxial relays in mu-metal cans. They are available with
a characteristic impedance of either 50 or 75 ohms. For
R.F. up to 2GHz, telecoms, video or high speed digital
switching up to 500 Mbits/sec. Contact technical sales
office for further data.
Series 109P 1 Form A, 1 Form C
The electrical specification and dimensions are identical
to the 1 Form A Series 109. They are encapsulated using
the same resins within a plastic package which features an
internal mumetal magnetic screen.
Series 109PH 1 Form A
The electrical specification is again identical but the mumetal screened plastic package is slightly different having
an increased stand-off from the printed circuit board.

The life of a reed relay will depend upon the switch load and the end of life
criteria. As an example, with an ‘end of life’ contact resistance specification
of 0.5 ohms, switching low loads (10 volts at 10mA resistive) or when ‘cold’
switching, typical life will be 1000 Million operations. At the maximum load
of 10 Watts (resistive), typical life will be 10 Million operations. In the event of
abusive conditions, for example high currents due to capacitive inrushes, this
figure will reduce considerably. Switch type number /1 is the prefered option
where higher currents are involved, switch type number /2 is prefered for low
level or ‘cold’ switching.
Pickering will be pleased to perform life testing with any particular load
condition, do not hesitate to contact our Engineering Department.

The device is encapsulated in a mu-metal can using a very high
resistivity resin. Mu-metal is used rather than steel because of
both its very high permeability and its low magnetic remanance.
This construction totally eliminates the risk of magnetic
interaction problems. Magnetic interaction is usually measured
as a percentage increase in the voltage required to operate a
relay when two additional relays, stacked one each side, are
themselves operated. An unscreened device mounted on this
pitch would have an interaction figure of around 40 percent,
it would therefore be totally unsuitable for applications where

Magnetic Interaction - An explanation
Magnetic interaction between relays is normally expressed as
a percentage increase in the voltage required to operate the
relay, due to the extraneous fields from adjacent relay coils.
An unscreened SIL relay of this size would have an interaction
figure of around 30 percent, i.e. the voltage required to
operate it will increase by this amount when relays alongside
are operated also. It may prove impossible to use such a relay
at its nominal coil voltage in high density applications.
A Pickering Series 107 reed relay has an interaction figure of
approximately 1 percent.

The Series 105 is a range of Single-in Line reed relays,
available with a wide variety of switching configurations and
switch types, including mercury wetted versions. They feature
internal mu-metal magnetic screens which allow high packing
density without the risk of magnetic interaction problems.
The Pickering Series 100, 101, 103, 106, 107 and 108 all have
the same pin locations as the Series 105. If a reduced coil
power is desired, please consider our Series 100 and 101
which may be driven directly from CMOS logic. If a higher
packing density is required, smaller devices are available in
other Pickering SIL ranges.
In addition to the relays shown on this brochure, many other
special types are manufactured to meet customers specific

A useful tip
If there is a chance that you might want to use mercury
wetted relays instead of dry relays at a later date, for example
to increase switch ratings, lay out the PCB initially as though
for the mercury wetted type with pin 1 uppermost. This allows
uprating later without PCB changes. The mercury versions
in the Series 105 have identical pin configurations to the dry
types.

Switch no.2 is particularly good for switching low currents and/or voltages. It is
the ideal switch for Automatic Test Equipment where cold switching techniques
are often used. Where higher power levels are involved, switch no.1 is a more
suitable choice.

The Series 104 is a range of Single-In-Line reed relays intended for
voltages that are beyond the capabilities of conventional SIL reed relays.
They are ideal for such applications as transformer or cable testing or any
other automatic test equipment where high voltages are involved.
Where mains voltages are switched, for example to control and isolate
S.C.R. or triac gates, they are an ideal choice.
One or two Form A (energize to make) or one Form B (energize to
break) configurations are available.
The range features an internal mu-metal screen to eliminate problems
that would otherwise be experienced due to magnetic interaction when
they are closely stacked.
Three types of dry switches are available, capable of standing-off 1,
1.5 or 3kV d.c. The 3kV version has an increased clearance between
the switch and coil pins to accomodate the higher voltage. Even higher
voltage ratings are available to special order, please contact our sales
office for further information.
Mercury wetted devices are also available for applications where bounce
free switching is required. These are rated at 1500 volts d.c. stand-off,
500 volts d.c. switching at up to 50 watts.

The Pickering Series 103 is a range of Single-in-Line reed
relays intended for such applications as wide bandwidth A.T.E.
switching matrices, attenuator switching or any other applications
where exceptionally low levels of inter-terminal capacitances
are required, for example, when carrying fast rise time pulses. A
version with an internal co-axial electrostatic screen is available
which is ideal for applications where capacitively coupled noise
from switch to coil connections is undesirable. The co-axial device
has a characteristic impedance of 50 ohms and is also suitable
for RF applications, HF performance is similar to the Series 102M.
The range consists of two basic types, the first achieves ultra low
capacitance levels of typically 0.1pf from each switch connection
to the coil and typically 0.08pf across the open switch contacts,
by virtue of an internal coaxial electrostatic screen or guard
connection. Where it is not possible to drive a guard, the second
type has inherently low capacitance figures of typically 0.4pf from
each switch connection to the coil and typically 0.1pf across the
open switch contacts. These figures for the unguarded version are
around one quarter of those for standard SIL devices. An internal
mu-metal magnetic screen is an option in both of these types.
The Series 103 may be stacked on 0.2 inches pitch and is
pin compatible with all other 0.2 inch SIL relays. They are
encapsulated in a plastic package using a very high resistivity
resins.
Two types of Form A (energize to make) switches are available,
a general purpose switch (switch no.1) and a vacuum sputtered
ruthenium switch (switch no.2) which is ideal for very low level or
“cold” switching applications.

In high density applications when more than one
relay may be operated at any time, for example, ATE
switching matrices, it is usually necessary to use a relay
that includes internal mu-metal magnetic screening.
Without this magnetic screening, the operate and
release voltages of the relays will be altered by the
extraneous fields from adjacent devices. This means
that when temperature effects are also considered, it
may not be possible to operate a relay at its nominal
coil voltage. A magnetic screen is therefore important
when relays are used in this way. The addition of this
screen does have the effect of slightly increasing the
capacitance figures of the relay, as illustrated in the
tables over.
When relays are not stacked closely or if adjacent relays
are never operated at the same time, it is often possible
to use a device without magnetic screening, thereby
achieving a slightly lower level of capacitance. In this
range therefore, magnetic screening is offered as an
option.

It is convenient to consider the internal capacitances as a delta network as
in the circuit diagram alongside. C1 is the capacitance between one end of
the switch and the coil, C2 is the capacitance between the other end of the
switch and the coil. These two figures will be approximately equal. C3 is the
capacitance across the open switch. When measuring the values of any one
of these capacitances, it is necessary to “guard” the unused relay connections
to avoid the parallel effects of the other capacitances, connection details
when performing these measurements on a capacitance bridge are shown
below. Relays with an internal electrostatic screen have the screen terminals
guarded in all cases.

The Series 102 is a range of subminiature coaxial reed relays for high
frequency applications up to 3 GHz, performance characteristics will be
found on reverse of this sheet. Two package types are available, both
displaying outstanding RF performance in terms of low insertion loss,
good isolation and excellent VSWR characteristics in 50 ohms systems.
These relays have good coil drive levels making them ideal for portable
applications or where space is at a premium. If an even smaller RF
relay is required, look at the Series 109RF or 111 RF.

The 102F package dispenses with the leadframe connections to the
switch and screen. These terminations are instead brought out axially
from the ends of the device where they are soldered directly to the
stripline. This technique allows very accurate matching to the 50 ohms
line and gives an excellent VSWR right up to 3 GHz.

Mounting method:
A small rectangular hole is punched into the printed circuit board or
notched into the board edge to accommodate the package. The switch
leads are then soldered directly to the 50 ohms stripline, the tin plated
copper foil from the screen is soldered directly to the ground plane on
the reverse side of the P.C.B. The coil connections are soldered directly

If your high frequency application does not require coaxial relays, Pickering
also manufacture devices featuring very low levels of capacitance between
the switch and coil, see our Series 103. These are especially useful for such
applications as the switching of ranges and attenuators in IEEE-488 controlled
instrumentation. Contact our sales office for further details.

The Series 101 have very high coil resistances. 5 Volt dry versions
may be driven directly from 74HC or 74HCT logic without the
need for additional drivers.
74HC logic will drive up to 4mA at 5 Volts, therefore a coil
resistance of 1600 ohms is desirable to avoid running the IC at
its maximum rating; 1600 ohms is the coil resistance of the single
pole dry Series 101. They may be stacked on 0.3 inches pitch
(7.6mm) and as they have an internal mu-metal magnetic screen,
there is no risk of magnetic interaction problems.
Both dry and mercury wetted switches are available in a range
of configurations and coil voltages. The switches in the 2 Form A
version are vertically stacked so the relay requires the same board
area as the 1 Form A type.
A special 1 Form A, 5 Volt version is available with an even
higher coil resistance of 3000 ohms. This is particularly suited to
applications such as battery powered portable equipment as it
requires a coil current of only 1.7 mA. This part, the 101-1-A-5/17
or 17D has the advantage of a lower level of thermal EMF of 3
microvolts or less.
Other special parts are also available that may be operated from
3 Volt logic.

Ve
Low thermal EMF relays
Direct drive from CMOS
FEATURES
l SoftCenter™ construction (see opposite)
l Highest quality instrumentation grade switches
l Thermal EMF about 1 microvolt or less
l Low power consumption, ideal for portable
equipment
l Encapsulated in a plastic package with internal
mu-metal magnetic screen
l Two pole relay requires the same board area as
the single pole type
l Insulation resistance greater than 1012 ohms for
dry Form A devices
l 3, 5, 12 and 24 volt coils are standard, with or
without internal diode
l 100% tested for dynamic contact resistance
The Pickering Series 100 is a complete range of Single-in- Line
(SIL) reed relays primarily intended for direct drive from 4000B
CMOS or NMOS logic or similar low current sources. The
mercury wetted relays in the range may be driven directly from
TTL logic.
They are also useful for applications where conservation of
current is important, for example, battery powered equipment.
The extremely low level of thermal EMF, about 1 microvolt or
less, of the dry versions make them ideally suited to applications
such as data acquisition or thermocouple switching.
An internal mu-metal magnetic screen is fitted to avoid the
effects of magnetic interaction between relays.
If you do not require quite such high coil resistances or if a
slightly smaller device is desired, please look also at our Series
101 which may be driven directly by 74HC or 74HCT logic.
Other special parts are also available that may be operated
from 3 Volt logic, please contact our Sales Office for further
information.

The Pickering Series 98 is a range of Dual-In-Line relays,
electrically equivalent to the Series 101 CMOS drive, Single-InLine types, but pin compatible with standard DIL relays. The
range features very high coil resistances, the 5 volt dry devices
may be driven directly from 74HC or 74HCT logic without the
need for additional drivers. Naturally, high resistance 12 and 24
volt coils are also available in this series.

74HC logic will drive up to 4mA at 5 volts which means that
a nominal coil resistance of 1600 ohms is required to avoid
running the IC at its maximum rating; 1600 ohms is the coil
resistance of the single pole dry Series 98. A special model with
an even higher coil resistance of 3000 ohms is also available, our
type number 98-1-A-5/17D (the D suffix indicates an internal
diode).
l )RUP$HQHUJL]HWRPDNHZDWWVDW9
It is often possible to replace TTL ICs with their equivalent CMOS
ones and replace standard DIL relays with Pickering Series 98, to
obtain the benefits of CMOS without any circuit or PCB redesign.
l )RUP$HQHUJL]HWRPDNHZDWWVDW9
The range like its SIL equivalent has an internal mu-metal
screen to enable high packing density with negligible interaction
between adjacent devices.

If there is a chance that you might want to use mercury wetted
relays instead of dry relays at a later date, for example to
increase switch ratings, lay out the PCB initially as though for the
mercury wetted type with pins 1 and 14 uppermost. This allows
uprating later without PCB changes. The mercury versions in the
Series 98 have identical pin configurations to the dry types.

PICKERING SERIES 97
Dual-In-Line DIL Reed Relays
FEATURES
l SoftCenter™ construction
l Encapsulated in a plastic package with internal
mu-metal magnetic screen
l Wide range of switch con¿gurations - 1 Form A,
1 Form B, 2 Form A, 1 Form C
l Dry and mercury wetted switches are available
with the same pin con¿guration and footprint
(see “A useful tip” below)
l 5, 12 and 24 volt coils are standard, with or
without internal diode
The Series 97 is a range of reed relays with pins in the popular
Dual-in-Line format.
Being encapsulated in a plastic package using a very high
resistivity epoxy resin gives the device several advantages over
the more usual moulded construction. The reed switches are
not subjected to the high temperatures and pressures of the
transfer moulding process with the inherent risk of damage to
the sensitive glass to metal seals. The construction incorporates
a mu-metal wrap around the operating coil to eliminate magnetic
interaction problems. Higher drive levels are achieved, allowing
a full range of switching configurations including 1 or 2 Form A
(energize to make), Form C (change-over) and Form B (energize
to break) in both dry and mercury wetted types.
If higher coil resistance levels are required, please look at our
Series 98 DIL relays which may be driven directly from 74HC or
74HCT CMOS logic.
A useful tip
If there is a chance that you might want to use mercury wetted
relays instead of dry relays at a later date, for example to
increase switch ratings, lay out the PCB initially as though for the
mercury wetted type with pins 1 and 14 uppermost. This allows
uprating later without PCB changes. The mercury versions in the
Series 97 have identical pin configurations to the dry types.

These ranges of reed relays are essentially the same as
the dry Series 80 and 85 and the mercury wetted Series
88 and 89 but with coil resistances between 2 and 3
times higher. This feature is particularly useful when
using large numbers of relays, to reduce overall current
requirements and heating effects, or when the available
coil drive power is restricted, for example, in battery
operated equipment.

away from the PCB
The Series 67 and 68 ranges of high voltage reed relays
have similar specifications to the established Series
60/65 and 62/63 but are constructed using a leadframe
in a Single-in-Line format and feature former-less coils
which enables a smaller package than is usual for this
type of device.
The unusual package style allows some interesting
stacking possibilities (see adjacent photo) when used to
construct high density multiplexers or matrices. The parts
feature an internal mu-metal magnetic screen.
They are available for up to 10kV stand-off, 7.5kV
switching at 50 Watts maximum. The tungsten plated
contacts ensure a long and reliable life.
5, 12, and 24 volt coils are available as standard
other voltages can be supplied to special order as can
variations in the lead length of the Series 68 type.

Notes
Note 1, Switching Voltage
This high voltage rating is for RESISTIVE loads only. At these high voltages,
circuit capacitance can generate very high current pulses which can damage the
contact plating. If there is capacitance in circuit, provision should be made to
limit the surge to within the current and power ratings of the relay. The product
of open circuit switch voltage and instantanious current at the point of switchon should not exceed the 50 Watts power rating of the contact. Exceeding this
level will reduce the operational life of the relay.
Note 2, Life expectancy
The life of a reed relay depends upon the switch load and the end of life
criteria. Typical life at low power levels or when ‘cold’ switching will be around
10 Million operations. At the maximum load (resistive), typical life will be
1 Million operations. In the event of abusive conditions, for example high
currents due to capacitive inrushes, this fi gure will reduce considerably.
Pickering will be pleased to perform life testing with any particular load
condition.
Note 3, Capacitance across open switch
This is measured with the coil connected to the guard terminal of the measuring
bridge.

PICKERING SERIES 62, 63
High Voltage Dry Reed Relays
for up to 15kV
FEATURES
l SoftCenter™ construction
l Up to 15 kV stand-off
l 12.5 kV switching
l Small size
l Easy mounting
l Long life
l Fully encapsulated
The Series 62 and 63 ranges of high voltage reed relays
feature push-on terminals and are supplied complete
with the appropriate connectors and insulating boots.
They are available for up to 15kV stand-off, 12.5kV
switching at 50 Watts maximum. Tungsten plated
contacts ensure a long and reliable life.
Both Form A (energize to make) and Form B (energize
to break) configurations are available and it is usually
possible to achieve a Form C (change-over) function by
using a Form A and a Form B type together.
These relays feature an internal mu-metal magnetic
screen which permits the Form A (energize to make)
versions to be mouted side by side. Special versions can
be manufactured with an electrostatic screen and/or
earth connection to the magnetic screen. This can often
be useful where EMC problems are encountered, please
contact our technical sales office.
Form B types are magnetically biased and should not
be mounted directly onto ferrous metal chassis or less
than 1 inch (25mm) away from other relays as the coil
operating voltage characteristics will be altered due to
magnetic interaction. The coils of Form B relays are
polarity sensitive, the positive connection is identified by
a red spot.
5, 12, and 24 volt coils are available as standard other
voltages can be supplied to special order.

Important. This is the maximum current rating at 50 Watts. If, for
example, you wish to switch 5000 volts, the maximum current
will be 10mA. Multiply your instantaneous switching current by
the voltage to be switched, to ensure that you do not exceed
this 50 Watts rating. Capacitive inrush currents can sometimes
be high due to the voltages involved, if possible insert a series
resistance into the circuit to limit this. Contact our Technical
Department for assistance if required.

current will be 10mA. Multiply your instantaneous switching
current by the voltage to be switched, to ensure that you do
not exceed this 50 Watts rating. Capacitive inrush currents can
sometimes be high due to the voltages involved, if possible
insert a series resistance into the circuit to limit this. Contact
our Technical Department for assistance if required.
