Reed Switches
The quality of our Reed Switches meets the very high
international standards.
The variety of the Reed Switch types and the stateof-the-art development enable us to cover almost all
industrial applications and specifications.
Our product range is complemented by the Reed
Switches of M/S OKI Sensor Device Corporation,
with whom we have an „International Distributor
Agreement“.
Our Reed Switches are available as normally-open,
normally-closed mounted with biasing magnet or
bistable versions.
The scope of implementing Reed Switches is farranging. Especially when developing new custom
applications, there may be the necessity to adapt the
Reed Switch geometry to special assembly situations.
By extending, cutting, bending or combinations
thereof we gain the ability to customize the Reed
Switch lead-outs to meet individual customer
requirements.
Since the use of SMT is intensifying especially
in industrial applications, our product range also
includes SMD and moulded Reed Switches with
common connectivity.
For use in automated mounting machines the SMD
Reed Switches are also available in Tape & Reel
packaging.

High Voltage Reed Relays
Our High Voltage Reed Relays have outstanding
performance characteristics in insulation resistance
and stand-off voltage and thus find application in
many electronic and electrotechnical areas.
Page 12 - 18
Reed Relays
A wide range of standard Reed Relays and our knowhow to develop customer specific Reed Relays allows
us to find a solution for almost every application
requirement.

SENSORS
Proximity Sensors
Proximity Sensors are based on Reed Switches which
are actuated without direct physical contact.
The switching operation is generally triggered by the
approach respectively by the removal of a magnetic
field.
Proximity Sensors are used in technical processes for
position detection of objects and tools, or as signal
source for security measures.
Proximity Sensors are implemented when mechanical
limit switches are unsuitable due to adverse operating
conditions, and when other non-contact switches such
as inductive and capacitive sensors are too expensive.
Aside the very good cost/performance ratio our
Proximity Sensors stand out due to their multi-purpose
applicability. This is obtained by the use of various
housing types in combination with diverse connectivity.
Individual solutions can be designed according to
customer specifications.
Page 24 - 25
Pendulum / Inclination Sensor
The Pendulum / Inclination Sensor for the
measurement of angles enables differential angles
above 2°. The Sensor’s repetitive accuracy allows its
use for very high precision requirements. The patented
Sensor replaces former mercury solutions and is used
in the automotive industry as well as in other fields of
industry and engineering.
Page 26 - 27
Automotive Sensor / ABS Sensor
The Automotive Sensor / ABS Sensor is designed
utilizing several Pendulum Sensors. When the preset
acceleration is exceeded the Pendulum with the fixed
magnet deflects and activates the Reed Switch.
The Sensor can be adjusted for accelerations above
0,1g. Other customer specific Automotive Sensors,
such as Door Lock Sensors and the like can also be
designed.
Acceleration Sensor / Crash Sensor
The Acceleration Sensor / Crash Sensor can detect
axial accelerations with an adjustable response value
beyond a prespecified g-force (multiple gravitational
acceleration). When the prescribed acceleration is
exceeded a flying magnet passes a Reed Switch
triggering contact.
Typical automotive applications include airbag and
seatbelt systems. The Acceleration Sensor can
be adjusted for accelerations above 2g to meet
preselected customer acceleration requirements as
well as other design/package specifications.

Indirect Actuation: Shielding
With the stationary arrangement of a Reed Switch and magnet, the
contact Reeds are closed. Should the magnetic field be diverted away
from the Reed Switch by a shield of ferro-magnetic material placed
between the switch and the magnet, the contacts will open. When the
shield is removed, the contact Reeds become magnetically actuated

cobalt alloy), a ceramic (barium ferrite or another metal oxide) or rare earth magnets.
Due to their specific magnetic characteristics, the types of magnets differ in shape:
ALNICO magnets are bar magnets with a length/diameter ratio of 3/1 to 5/1; oxide
magnets are generally disc or moulded magnets. Also important to note is the difference
in temperature coefficient: ALNICO: 0.02 %/K, oxide: 0.2 %/K

Life Expectancy:
The life expectancy of a Reed Switch is about 105...106 switching cycles with maximum power. With a low load the life expectancy can reach
5x108 operations. The mechanical life expectancy can reach at least 109 operations. Through the switching of inductive, capacitive
and lamp loads, the life expectancy is considerably reduced due to exceeding the specified maximum current.
In General:
For all Reed Switches the standard pull-in sensitivity is given
in the table. Other pull-in sensitivities are available on request.
Normally Closed and Bistable Reed Switches:
All Reed Switches are available in a normally closed or
bistable version.
Pull-In Sensitivity Tolerance:
The given pull-in sensitivity of the Reed Switch has a test
equipment tolerance of ± 2 AT.

HIGH VOLTAGE REED RELAYS
Introduction
GÜNTHER® High Voltage Reed Relay technology is based upon our extensive experience in the design and
manufacture of Reed Switches and Reed Relays.
GÜNTHER® High Voltage Reed Relays have outstanding performance characteristics in insulation resistance and
stand-off voltage. The high dielectric stand-off voltage between the open contacts as well as the high switching
voltage are achieved by using high vacuum Reed Switches. A proven assembly and potting technique assures
the following relay characteristics:
● Stand-off voltage across open contacts from 3 KV up to 14 KV max.
● Stand-off voltage between coil and contact from 10 KV up to 25 KV max.
● Switching voltage from 1.5 KV up to 10 KV max.
GÜNTHER® High Voltage Reed Relays are offered in a variety of contact configurations:
● 1 N.O., 2 N.O. or 4 N.O. contacts (normally open contacts)
● 1 N.C. (normally closed contact)
● 1 N.C. / 1 N.O. (1 normally closed contact/ 1 normally open contact)
GÜNTHER® High Voltage Reed Relays offer mounting flexibility enabling the customer to match different
application requirements:
● Coil and Reed Switch connecting pins in the base plate for PCB mounting.
● Coil connecting pins in the base plate for PCB mounting and Reed Switch connections with cable.
Cable length: standard 200 mm
● Coil connecting pins in the base plate for PCB mounting and Reed Switch connecting pins on top of the relay.
GÜNTHER® High Voltage Reed Relays have additional features:
● Immunity against harsh environmental conditions (eg. high humidity) by using hermetically
sealed switching contacts potted in a strong plastic case.
● High shock and vibration resistance.
● Low contact capacitance and high switching frequency in comparison with electro-mechanical, open relay
contacts.
● Washable and resistant to standard automatic cleaning methods.
GÜNTHER® High Voltage Reed Relays find application in many areas of the electrotechnical and electronic
industry:
● Electronic medical equipment
● Cable tester arrays and cable test equipment
● Copy machines
● Laser optical systems and infra-red equipment
● Test equipment

Switches with contact code 90-92 are tungsten-plated and should be used only for switching power above approx. 10 mW.
Dielectric Strength
Tested in a radiation (e.g. light, x-ray)
free environment by applying a DC
voltage across the open contacts,
between adjacent contacts and between
coil and contact. The trigger current
is 100 µA. The unused contacts should
not be connected during the test.
Switching Time

Switches with contact code 90-92 are tungsten-plated and should be used only for switching power above approx. 10 mW.
Life Expectancy
The life expectancy of a Reed Relay is at least
105...106 operations at nominal load. At minimum
load the life expectancy can endure up to 5 x 108
operations. The mechanical life expectancy is 109
operations (minimum).
Through the switching of higher loads, especially inductive or capacitive and lamp loads, life
expectancy can be considerably reduced due to
exceeding the permissible maximum current.
Shock and Vibration
During shock and vibration tests the relays must be
energized with nominal voltage. The contact should
not open or close longer than 10 µs.
Vibration stability: 20 g/50 … 500 Hz
Shock stability: 35 g/11 ms half sine wave.
Proper contact protection will reduce electromagnetic interference and rapid contact erosion. Suppressing diodes in connection with inductive loads
may cause extreme contact wear.

Switches with contact code 90-92 are tungsten-plated and should be used only for switching power above approx. 10 mW.
Through the switching of higher loads, especially
inductive or capacitive and lamp loads, life expectancy can be considerably reduced due to
exceeding the permissible maximum current.

General Parameters
Life Expectancy
The life expectancy of a Reed Relay is at least 105...106 operations at
nominal load. At minimum load the life expectancy can be up to 5 x 108
operations.
The mechanical life expectancy is 109 operations (minimum).
Through the switching of higher loads, especially inductive or capacitive
and lamp loads, life expectancy can be considerably reduced due to
exceeding the permissible maximum current.

REED RELAYS
Customer Specific DIL-REED RELAYS
Introduction
The customer specific Reed Relays are Dual-In-Line-Relays with standard housing height of 7,5
mm and a base area of 19 x 10 mm.These relays are potted with a permanent flexible plastic
material subject to no mechanical force.
The advantage of the customer specific DIL-Reed Relays is that a wide variation of special pin
configurations, contact arrangements and other applications can be realized. S.T.G. is thus able to
produce the relay to meet special customer requirements.
Due to the small housing these relays can replace standard housing relays mounted on a PCB.

Tilt Switch:
At a specific angle, the reed switch is activated. By changing
the position of the sensor on the object, the switching angle
can be changed.
Acceleration sensor:
Acceleration will activate the pendulum. The switching
activating point corresponds to a specific deflection ß and
thus to a specific acceleration. The acceleration can be
calculated according to the following formula:
27
a = tanß * g
If the switching angle at a specific
acceleration is needed, the following
formula is applicable:
ß
m*a

RELATION ACCELERATION / ANGLE
ß = arctan a * g
ß = Switching angle
a = Acceleration
g = Gravity acceleration (9,81 m/s2)
PLEASE NOTE:
The inclination of the object influences the acceleration!
The sensor is filled with silicon oil!
