Description
These rope operated safety switches are installed on machines or conveyor belts, to activate the simple stop of the machine on every
hand intervention on the rope, from any point.
Provided with self-control function, they constantly check their correct operation, signalling with the opening of the contacts an
eventual loosening or breaking of the rope.
Orientable heads
Removing the four fastening screws, in all switches, it is
possible to rotate the head in 90° steps.
Protection degree IP67
These devices are designed to be used in the
toughest environmental conditions and they pass
the IP67 immersion test acc. to IEC 60529.
They can therefore be used in all environments where the maximum
protection of the housing is required.
Adjustment point indicator of the rope
The switches (head 79 and
80) are provided with a green
ring that shows the area of
the correct tightening of the
rope. The installer has only to
tighten the rope until the black
indicator will be in the middle
of the green area. If a traction
(or loosening) of the rope it
Area of correct rope
is high enough to permit the
tightening
black indicator to go outside
the correct tension area, the safety contacts will open.
Tension indicator
Extended temperature range
This range of switches is also available in a
special version with an ambient operating
temperature range of -40ºC to +80ºC.
They can be used for applications in cold stores, sterilisers and other
devices with low temperature environments. Special materials that
have been used to realize these versions, maintain unchanged their
features also in these conditions, widening the installation possibilities.
Actuating forces
These switches can be supplied
with reduced hardness internal
springs on request. This makes
it possible to reduce the physical
effort required to actuate the
switch, whilst maintaining the
actuating stroke of the electrical
contacts unchanged. Particularly
suitable for spans of reduced
dimensions, they must always
be matched to the suspension
of the rope pulley.

In the rest position (with rope correctly
tightened) the two contacts of contact
block 8 are both closed and
are activated respectively
by tightening or loosening
the rope. In order to use
this contact block for
safety applications it is necessary to
connect the two contacts in series. For
this reason, in the wiring diagrams the
contact block 8 is indicated as 1NC,
whereas in travel diagrams both contacts
are indicated.

In
the
diagram,
the
suggested
max.
rope
lengths with regard to
changes of temperature
(thermal
differential)
to which the switch is
expected to be exposed
in the working area are
indicated. For instance,
for an installation acc. to
example C which expects a
thermal differential of 30°C,
a max. rope length of 10
meters is suggested.

Adjustment of the operating point
For switches with head 79 and 80: Tighten the rope
connected to the switch, until the end of the indicator (1) reaches about the middle of the green ring (2).
General Catalogue 2015-2016
For switches with head 74: Tighten the rope connected
to the switch until the thimble will be at about 4 mm from
the head.
