Horizontal

Can be adjusted in 90° steps

Mounting plate

A mounting plate for supporting the escape release is included.

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

CTP‑L1Guard locking actuated by spring force applied and power-ON released (closed-circuit current principle)
