Permissible installation position

Fixcode evaluation

An actuator CES-A-BBN-C04-115271 is permanently allocated to the switch. The switch can be operated only with this actuator. The actuator is taught-in at EUCHNER prior to delivery. No additional actuators can be taught in.

Category according to EN 13849-1

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

  • Category 4/PL e according to EN 13849-1

Important: To achieve the stated category according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must be evaluated.
