CET3-AP-CRA-CH-50F-SA-C2312-157287 (Order no. 157287)

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

CET3

Closed-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 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.
