Approach directionCan be adjusted in 90° steps
Each actuator is unique. The evaluation unit detects only the actuator that has been taught-in. Additional actuators can be taught in.
Category according to EN ISO 13849-1Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN ISO 13849-1

Attention:The operating distance may vary depending on the background material and installation situation.
(Only in combination with actuator CES-A-BBA, CES-A-BCA)
Typical operating distance
For a side approach direction for the actuator and safety switch, a minimum distance of s = 4 mm must be maintained so that the operating distance of the side lobes is not entered.
(Only in combination with actuator CES-A-BPA)
Typical operating distance
For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the operating distance of the side lobes is not entered.
