- Up to 20 switches in series
- Short circuit monitoring
- 2 safety outputs (semiconductor outputs)
- Category 4 / PL e according to EN ISO 13849-1
- With 2 plug connectors M12
- Multicode
- Escape release, 75 mm long
- Lockout mechanism
- Multicode

Approach direction
Horizontal
Can be adjusted in 90° steps
Escape release
This is used for manual release of guard locking from the danger zone without tools.
Lockout mechanism
The lockout bar can be used to prevent maintenance personnel from being unintentionally locked in the danger zone, for example.
Important: The lockout bar is not a safety function.
This device with lockout bar possesses no auxiliary release.
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.

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.
