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. All products (except FW series) are
equipped with a particular mechanical hooking that does not allow the separation of the head from the body during its positioning.
Description
Rotating heads
Removing the two
fastening screws, in all
switches, the head can be
rotated in 90° steps.
Actuator regulation zone
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)
Versions with 30 N actuator extraction force
Versions with 30 N actuator
holding force instead of
the standard 10 N are
available.
Not detachable head
The action head type “93” is completely
interchangeable and compatible with
previous head type “92”, but it has the
advantage to be not detachable from the
switch body even if it is always adjustable
in 90° steps (Pizzato Elettrica patent).
The new head is safer because it cannot
be ruined during installation. The head
xing screws have been reduced to only
two (instead of the previous four) and so
the rotation operation will be quicker and
cheaper.
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 inammable gas is present.
