Description
These safety switches are ideal to control gates, sliding doors and other guards protecting dangerous parts of machine.
The stainless steel actuator is fastened to the moving part of the guard, so it is removed from the switch on every opening of the guard. The
switch mechanism guarantees that removing the actuator forces the positive opening of the electrical contacts. Easy to install, these switches
can be applied to any kind of protection (with hinge, sliding and removable ones). Besides, the possibility to actuate the switch only with its
actuator guarantees that the machine can be restarted only when the guard has been closed. Made of rugged materials and with oversized
thickness, these switches are designed for the use on heavy guards.
Rotating heads
Actuator regulation zone
Removing the two fastening
screws, in all switches, the
head can be rotated in 90°
steps.
Installation examples
0,5
...
5m
m
This switch has a wide backlash
of the actuator into the head (4,5
mm) for an easier installation.
With closed door, check that the
actuator doesn’t knock straight
against the head of the switch; it
must be in the adjustment zone
(0,5…5 mm)
Safety screws for actuators
These new screws have tamper-resistant Torx
buttonheads.
Devices fixed with this kind of screws cannot be
removed or tampered by common tools.
See Accessories page 6/5.
Limits of utilization
Do not use where dust and dirt may penetrate in any way into the
head and deposit there, in particular where metal dust, concrete or
chemicals are spread.
Do not use where explosive or inflammable gas is present.
Use Atex products in environments with explosion hazard (see page
2/137).

NC contact has to be considered with inserted actuator. In safety applications
it is necessary to activate the switch at least up to the positive opening point
indicated in the diagrams with the symbol . Operate the switch at least with the
positive opening force, indicated between brackets, below each article, next the
value of minimum force.
