Description
These safety switches are ideal for controlling gates, sliding doors and other guards which protect dangerous parts of machines
without inertia.
The stainless steel actuator is fastened to the moving part of the guard in such a way that it is separated from the switch each time
the guard is opened. A special mechanism ensures that removing the actuator forces the positive opening of the electrical contacts.
Easy to install, these switches can be used with all types of guards (with hinge as well as sliding and removable types). The possibility to actuate the switch only with a specific actuator guarantees that the machine can be restarted only after the guard has been
closed. These switches are made of robust materials with larger dimensions and are designed especially for heavy gates and harsh
environments.
2
Head with variable orientation
For all switches, the head can
be adjusted in 90° steps after
removing the two fastening
screws. In this way it is possible to actuate the switch
from 5 different directions.
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.
Wide-ranging actuator travel
The actuation head of this switch
0,5 ... 5 mm
features a wide range of travel.
In this way the guard can oscillate along the direction of insertion (4.5 mm) without causing
unwanted machine shutdowns.
This wide range of travel is available in all actuators in order
to ensure maximum device
reliability.
Safety screws for actuators
As required by EN ISO 14119, the actuator must
be fixed immovably to the door frame. Pan head
safety screws with one-way fitting are available
for this purpose. With this screw type, the actuators cannot be removed or tampered by using
common tools. See accessories on page 310.
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
Laser engraving
All devices are marked using a dedicated
indelible laser system. These engravings are
therefore suitable for extreme environments
too. Thanks to this system that does not use
labels, the loss of plate data is prevented and
a greater resistance of the marking is achieved over time.

IMPORTANT:
The state of the NC contact refers to the switch with inserted actuator. In safety
applications, actuate the switch at least up to the positive opening travel shown
in the travel diagrams with symbol . Actuate the switch at least with the positive
opening force, reported in brackets below each article, next to the actuating force
value.
Limits of use
Do not use where dust and dirt may penetrate in any way into the head and deposit there. Especially not where powder, shavings, concrete or
chemicals are sprayed. Adhere to the EN ISO 14119 requirements regarding low level of coding for interlocks. Do not use in environments with
presence of explosive or flammable gas. In these case use ATEX products (see dedicated Pizzato catalogue).
