Euchner CEM-AR-C40 transponder-coded safety switch

Euchner has expanded its range of transponder-coded safety switches with the CEM-AR-C40, which features solenoid and integrated evaluation electronics. The safety switch is used in applications that require guard locking for process protection. The solenoid achieves a locking force of 600 N and prevents safety devices from being opened unintentionally when guard locking is not active.

The transponder signals are evaluated in the safety switch when the safety guard is closed, and if the signals match, the two safe semiconductor outputs are switched. When controlling the solenoid, the guard locking is activated and the locking force tested. If the force is greater than 400 N, a status signal is transmitted to the control system.

The safety switch also features adhesive force adjustment and can be adjusted in three levels from 0 to 50 N. It offers various diagnostic options as well as 2 x 4 LEDs in the housing. The LEDs display important information about the product’s status and are clearly visible from all directions. Electrical connection is simple via plug connectors.

For larger installations with several safety doors to be monitored, up to 20 CEM-AR-C40 devices or other Euchner AR products can be connected in a series.
