Description
These rope-operated safety switches are installed on machines or conveyor belts and facilitate the simple shut-down of the machine
from any point and with any pull on the rope.
Provided with self-control function, they allow the constant monitoring of correct functioning, signalling with the opening of the
contacts an eventual loosening or breaking of the rope.
Head with variable orientation
8
For all switches, the head can be adjusted in 90° steps after
removing the four fastening screws.
Protection degree IP67
These devices are designed to be used in the
toughest environmental conditions and they pass
the IP67 immersion test acc. to EN 60529. They
can therefore be used in all environments where maximum protection degree of the housing is required.
Indicator for rope adjustment
Tension
indicator
Area of correct rope
tightening
electrical safety contacts will open.
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 the tension (or loosening) on the rope
is so high that the black indicator exits the green area, the
Extended temperature range
These devices are also available in a special
version suitable for an ambient operating temperature range from -40ºC up to +80°C.
They can therefore be used for applications in cold stores, sterilisers
and other equipment with low temperature environments. The special materials used to produce these versions retain their characteristics even under these conditions, thereby expanding the installation
possibilities.
Actuating forces
These switches can be supplied
with reduced hardness internal
springs on request. The force
required to actuate the switch
can thereby be reduced without
changing the actuating path of
the electrical contacts. This is
particularly advantageous for
smaller spans, but must, however, always make use of rope
pulleys.

In the rest position (with rope correctly tightened) the
two contacts of con-
tact block 8 are both
closed and are acti-
8
8.51
vated 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.

The max. recommended
spans are indicated in the
diagram as a function of the
temperature fluctuations
(temperature differences)
to which the switch may be
exposed at the point of use.
For instance, with installation of type C and a temperature difference of 30°C,
the max. recommended
rope length is 10 metres.
