Non-contact safety switch CET-AP-…, M12

  • Safety switch with guard locking and integrated evaluation electronics
  • Locking force up to 6,500 N
  • Short circuit monitoring
  • 2 safety outputs (semiconductor outputs)
  • Category 4 / PL e according to EN ISO 13849-1
  • With 1 plug connector M12, 8-pin
  • Unicode
  • Door monitoring output
  • Indication of the door position by LED
  • Approach direction A (delivery state)

Approach direction


Can be adjusted in 90° steps

Safety switch

The device may be operated only in conjunction with the actuator CET-A-….

Important: The actuator must be ordered separately.

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.

Solenoid operating voltage

  • DC 24 V +10%, -15%

Guard locking type

CET3Closed-circuit current principle, guard locking by spring force. Release 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). OUT output D also remains set when guard locking is active.

Category according to EN ISO 13849-1

Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

  • Category 4 / PL e according to EN ISO 13849-1
  • The stated safety characteristics apply to any installation orientations of the safety switch.

Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.
