CTP-L2-AP-U-HA-AZ-SA-EX-175620 (Order no. 175620)

Description

Version ATEX

Suitable for use in zones 2 and 22 (gases and dusts).
Areas of application:
II 3 G
II 3 D

Approach direction

Horizontal

Can be adjusted in 90° steps

Guard locking principle

Open-circuit current (power on to lock): On a guard with guard locking based on the open-circuit current principle, the guard is locked until the power supply to the guard locking solenoid is interrupted. Unlocking is by spring force. The term electrical guard locking is also used.

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.
