  • Safety switch with guard locking and integrated evaluation electronics
  • Locking force up to 6,500 N
  • Direct connection to decentralized peripheral systems (e.g. ET200pro)
  • Short circuit monitoring
  • Two safety outputs (semiconductor outputs)
  • Up to category 4/PL e according to EN ISO 13849-1
  • With two plug connectors M12
  • Unicode
  • Escape release, 105 mm long
  • Indication of the door position by LED
  • Approach direction A (delivery state)
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. Solenoid operating voltage
  • DC 24 V +10% -15%
Guard locking type
CET3Guard locking by spring force. The door position is also monitored. LED 2 illuminates as soon as the actuator is above the extended plunger (state: door closed, guard locking not active). LED 2 also remains on when guard locking is active.

Category according to EN ISO 13849-1Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
  • Category 4/PL e according to EN ISO 13849-1
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated. The category is dependent on the installation position of the safety switch: Escape releaseThis is used for manual release of guard locking from the danger zone without tools.
