Euchner Euchner CTP-L1-AR-U-HA-AZ-SH-123362 

ORDER NO. 123362

Transponder-coded safety switch CTP-AR, M23

• Safety switch with guard locking and integrated evaluation electronics
• Up to 20 switches in series
• Short circuit monitoring
• 2 safety outputs (semiconductor outputs)
• Up to category 4/PL e according to EN ISO 13849-1
• With plug connector M23
• Unicode
• Door monitoring output
• Approach directions A, B and C (delivery state)

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

CTP-L1

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