Non-contact safety switch CET-AR-…, M12, with escape release and lockout bar

  • Safety switch with guard locking and integrated evaluation electronics
  • Locking force up to 6,500 N
  • Up to 20 switches in series
  • Short circuit monitoring
  • 2 safety outputs (semiconductor outputs)
  • Category 4 / PL e according to EN ISO 13849-1
  • With 2 plug connectors M12
  • Multicode
  • Escape release, 75 mm long
  • Lockout mechanism
  • Multicode
  • Approach direction A (delivery state)

Approach direction


Can be adjusted in 90° steps

Escape release

This is used for manual release of guard locking from the danger zone without tools.

Lockout mechanism

The lockout bar can be used to prevent maintenance personnel from being unintentionally locked in the danger zone, for example.

Important: The lockout bar is not a safety function.

This device with lockout bar possesses no auxiliary release.

Safety switch

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

Important: The actuator must be ordered separately.

Multicode evaluation unit

Every suitable actuator is detected by the switch.

Solenoid operating voltage

  • DC 24 V +10%, -15%

Guard locking type

CET1Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

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.
