2. Product description
The MC36CH safety sensor features one or more reed contacts that are activated without contact through the coded
magnetic field of the actuator MC36CM.
The MC36CH safety sensors are suited for gate/door monitoring applications and can reach PL e, safety category 4
according to EN ISO 13849-1.
The sensors are only a subset of the safety-related parts of the machine: the safety level of the entire system depends also
on all the other safety components and devices of the system set.
As application example, if a door is opened, the actuator moves away from the sensor which is positioned on the
stationary part of the guard.
If the new position of the actuator reaches the safe switch-off distance (Sar), the switching status can be communicated to
a connected safety relay.
The sensors have onboard N.O. and/or N.C. safety contacts, operated when the corresponding MC36CM actuator is
close to the sensor.
All the MC36CH/MC36CM pairs described in this manual make up a multiple flow redundant Type 4 coded system with
low-level coding, as defined in the standard EN ISO 14119. The design of the MC36CH sensors and of the MC36CM
actuators results in MC36CH/MC36CM pairs which cannot be easily operated by readily available instruments, increasing
the safety level of the application.
The user is responsible for the risks evaluation of the safety system; he decides with complete responsibility if the products
described in the user manual are suitable for his application.
The MC36CH/MC36CM sensors do not require internal maintenance: if they are tampered with, they lose their safety
functions and the guarantee is annulled.
Note:
the meanings of “Normally Open” and “Normally Closed” contact throughout this manual are the
following:
N.O.: contact is open and non-conductive when sensor is not operated with actuator magnet MC36CM
away from the sensor.
N.C.: contact is closed and conductive when sensor is not operated with actuator magnet MC36CM away
from the sensor.
