Features CET4-AR-CRA-AH-50X-SH-110201 110201

  • 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
  • Teach-in input
  • Approach direction A (default setting on delivery)
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
CET4Open-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.
