3 Product description
3.1 Structure and function
The safety switch is an interlocking device with a locking device consisting of a non-con‐
t
act 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. If 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.
