- Guard lock monitoring output OL
- Plug connector M12, 8-pin

Description
Version ATEX
Suitable for use in zones 2 and 22 (gases and dusts).
Application area
II 3G D.
Guard locking principle
Power to unlock: On a guard with guard locking based on the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with power. Unlocking is by solenoid force. The term mechanical 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.
Terminal assignment
Accessories required
Actuator is not included.
The safety switch can only be actuated in conjunction with the actuators provided for this purpose.
