Approach direction

Can be adjusted in 90° steps

Short circuit monitoring

The switch generates its own clock signal on the
output lines OA/OB.
Pay attention to this aspect when connecting to
control systems and relays.

Unicode evaluation

Each actuator is unique. The evaluation unit de­tects only the actuator that has been taught-in.
Additional actuators can be taught-in.
Only the last actuator taught-in is detected.

Multicode evaluation

Every actuator is detected by the evaluation
unit.

Fixcode evaluation

An actuator is permanently allocated to the evalu­ation unit. The evaluation unit 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 in accordance with EN ISO 13849-1

Due to two redundant design semiconductor
outputs (safety outputs) with internal monitoring
suitable for:

f

Category 4 / PL e in accordance
EN ISO 13849-1

Important: To achieve the stated category in
accordance with EN ISO 13849-1, both safety
outputs (OA and OB) must be evaluated.
