Specification
Approach direction
Horizontal
Can be adjusted in 90° steps
Safety switchThe device may be operated only in conjunction with the actuator CET-A-....
Important: The actuator must be ordered separately.
Each actuator is unique. The switch detects only taught-in actuators. Additional actuators can be taught in. Only the last actuator taught in is detected.

CET4 | Open-circuit current principle guard locking by solenoid force. Activation of the guard locking by applying voltage to the guard locking solenoid. The door position is also monitored. The door monitoring output OUT D is set to HIGH as soon as the actuator is above the extended plunger (state: door closed, guard locking not active). The output OUT D remains set also with guard locking active. |
