CTM-I2-BR-U-AZ-SA-168250 (Order no. 168250)
Transponder-coded safety switch CTM-I2-BR, M12
- Guard locking only suitable for process protection: The safety outputs are switched on when the door is closed.
- Series connection possible
- Open-circuit current principle
- Category 4 / PL e according to EN ISO 13849-1
- Actuating/extraction/retention force: 20/18/5 N
- Plug connector M12, 8-pin
- Auxiliary release
- Unicode

Description
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
CTM‑I2 | Guard locking actuated by power-ON and released by spring force (open-circuit current principle). |
Series connection
Safety switches in the version CTM-...-BR can be integrated into a BR device chain. You will find further information about series connection in the operating instructions for the device.
