CTP-L1-AP-U-HA-AES-SA-157112 (Order no. 157112)

Description

Medium-resistant stainless-steel version

Robust, tough and largely media resistant. Critical components such as plugs, cover screws and guide bushes, etc., consist of high-quality inox steel.

Approach direction

Figure

Figure

Horizontal

Can be adjusted in 180° 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

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

Escape release

This is used for manual release of guard locking from the danger zone without tools.
