- Open-circuit current principle
- Unicode
- Monitoring output guard locking OUT
- Monitoring output door position OUT D
- Plug connector M12, 8-pin

Description
Guard locking principle
Open-circuit current (power on to lock): On a guard with guard locking based on the open-circuit current principle, the guard is locked until the power supply to the guard locking solenoid is interrupted. Unlocking is by spring force. The term electrical guard locking is also used.
Unicode evaluation
Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in.
Only the last actuator taught-in is detected.
Safety characteristics
Thanks to two redundant safety outputs (semiconductor outputs) with internal monitoring, the device is suitable for:
- Category 4 /PL e according to EN 13849-1
- SIL 3 according to EN IEC 62061 Table 4
The OSSD outputs used check their function for short circuits and short circuits with test pulses.
