CTM-L2-BR-M-AZ-SA-166870 (Order no. 166870)

Description

Multicode evaluation

Every suitable actuator is detected by the switch.

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.
