CES-A-C5H-01-EX (Order no. 097945)

Description

Approach direction

Can be adjusted in 90° steps

Protective plate

A protective plate included protects the safety switch against impacts on the housing and the ingress of an explosive atmosphere.

Unicode evaluation

Each actuator is highly coded (unicode). The evaluation unit detects only actuators that have been taught-in. Additional actuators can be taught-in.

Category according to EN ISO 13849-1

Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

  • CES-A-C5H-01, category 4/PL e according to EN ISO 13849-1
