CET4-AP-CRA-CH-50F-SA-161178 (Order no. 161178)

Description

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.

Multicode evaluation

Every suitable actuator is detected by the switch.

Solenoid operating voltage

  • DC 24 V +10%, -15%

Guard locking type

CET4

Open-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 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.

Escape release

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