Product Overview
Structure and Function
The safety switch is an interlocking device with a locking device consisting of a
non-contact sensor with locking solenoid and a coded actuator. The actuator has
a low coding level.
If the protective device is closed, the actuator is led to the sensor. When the
actuation field is reached, the actuator code is read out and evaluated by RFID. If
the code is valid, the safe output signal switching device (OSSD) switches.
If the locking solenoid is supplied with power, the locking device is active.
