CTA-L1-BP-U-HA-AP-SA-166702 (Order no. 166702)

Description

Approach direction

Horizontal

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

CTA‑L1

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