Safety switch CTM-BR

Versatile in use

The CTM reliably secures smaller safety doors and flaps on machines and systems. Thanks to the integrated guard locking and guard lock monitoring, it can be used for both process and personal protection.
The compact design allows space-saving attachment to the safety guards. The very robust plastic housing and the high degree of protection IP 65 / IP 67 / IP 69 / IP 69K make the CTM an all-rounder for almost any industrial use.
With its smooth surfaces, rounded edges and materials that are resistant to cleaning agents, the CTM is particularly suitable for use in the food and packaging industries.

Mounting; assembly and function

The CTM consists of two components, a safety switch and a separate actuator. During mounting; assembly, the safety switch is attached to the fixed part and the actuator to the movable guards, while the small dimensions (120 mm x 36 mm x 25 mm) make it particularly easy to integrate into any machine design.
Thanks to the innovative ball actuator, the smallest door radii from 150 mm swivel radius can be realized. An integrated latching force (25 / 50 N) effectively prevents the door from opening unintentionally when it is not locked. When the guard is closed, the actuator inserts into the opening of the safety switch.
If the transponder chip built into the actuator is detected and the guard locking is actuated, the safety outputs are switched on. Thanks to the integrated prevention of inadvertent locking position (faulty closure protection), accidental activation of the safety outputs is prevented if the actuator is not fully inserted into the guard locking opening.

Series connection

Series connection in the control cabinet:
The wiring takes place in the control cabinet. All information about the status of the individual CTMs can be forwarded directly to the control system.
Series connection in the field:
For field wiring, EUCHNER offers the option of using M12 plugs and Y-distributors to connect several CTMs together.
A passive distribution module can also be used instead of the Y plug connector(s). With this device, all safety and status signals are collected in the field and passed on to the control system via a single cable.
