CTM-L2-BR-U-AZ-SA-168866 (Order no. 168866)

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‑L2

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

series connection

Safety switches in the CTM-...-BR version can be integrated into a BR device chain. Further information on series connection can be found in the operating instructions for the device.
