Euchner CTP-L1-AP-U-HA-AZ-SA-EX-129512 Transponder-coded safety switches according to ATEX directive

Approach direction Horizontal Can be adjusted in 90° steps Each actuator is unique. 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?L1

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