  • Safety switch with guard locking and integrated evaluation electronics
  • Locking force up to 6500 N
  • Up to 20 switches in series
  • Short circuit monitoring
  • 2 safety outputs (semiconductor outputs)
  • Up to category 4/PL e according to EN ISO 13849-1
  • With plug connector M23 (RC18)
  • Unicode
  • Door monitoring output
  • Approach direction A (default setting on delivery)
Approach direction Horizontal 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. 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
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). The output OUT D remains set also with guard locking 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
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: Dimension drawing Block diagram CET: Transponder-coded safety switch with guard locking Dimension drawingBlock diagram Technical dataApprovals Mechanical values and environment
