CTP-L1-AP-U-HA-AZE-SH-156056 (Rend. sz. 156056)


Approach direction


Can be adjusted in 90° steps

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.

Guard locking type


Guard locking actuated by spring force and power-ON released (closed-circuit current principle).

Lens set

The color of the pushbuttons can be selected using the lens set included (5 colors). Item no.: 120344 (see Accessories).
