EUCHNER is expanding its range of transponder-coded safety switches by a version with solenoid and integrated evaluation electronics. The new CEM-C40 is used in applications requiring guard locking for process protection. The solenoid achieves a locking force of 600 N and effectively prevents safety devices from being opened unintentionally. When the safety guard is closed, the transponder signals are evaluated in the safety switch. If the signals match, the two safe semiconductor outputs are switched. When controlling the solenoid, the guard locking is activated and the locking force is tested. If the force is > 400 N, a status signal is transmitted to the control system.
The CEM-C40 features adhesive-force adjustment. It can be adjusted in 3 levels from 0 to 50 N and prevents a safety door from opening unintentionally when guard locking is not active. The CEM-C40 offers various diagnostic options. In addition to detailed evaluation via status signals on the control system, it features 2 x 4 LEDs in the housing. These LEDs are easily visible from all directions and display all important information about the device’s status. Electrical connection is realized simply 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 series.
