CES-AH-C03-AE-LS-110370 (Rend. sz. 110370)


Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in.

Only the last actuator taught-in is detected.

Category according to EN ISO 13849-1

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

  • Category 3/PL d according to EN ISO 13849-1

Each safety path is independently safe.
