CET2-AR-CRA-CH-50F-SG-C2312-109941 (Order no. 109941)

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 unit

Every suitable actuator is detected by the switch.

Solenoid operating voltage

  • DC 24 V +10%, -15%

Guard locking type

CET2

Open-circuit current principle, guard locking by solenoid force. Activation of the guard locking by applying voltage to the guard locking solenoid.

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.

The category is dependent on the installation orientation of the safety switch:

Escape release

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