Transponder-coded safety systems CEM with guard locking for process protection More than safety.

Transponder-coded safety systems CEM CEM safety systems are modern interlocking devices for the protection of persons, machines and processes. Based on transponder technology, they combine a safety door monitor and a solenoid in a single system. CEM products are used in safeguarding movable guards for reliable detection of doors in closed position and guard locking for process protection. n Layout The CEM systems essentially consist of the following components: Actuator with coded transponder and movable anchor plate Guard locking solenoid Read coil Evaluation electronics n Simple function...

n Actuator The actuator’s spring-mounted anchor plate can be deflected up to an angle of ±4°. This allows the actuator to adjust itself independently to the surface of the CEM guard locking solenoid when the door is closed. n Simple compliance with standards Transponder coding ensures maximum safety. The requirements of relevant standards can be met with only a single CEM system. Irrespective of whether category 4 / PL e according to EN ISO 13849-1 must be achieved or whether the requirements in EN ISO 14119 must be met – you’re always on the safe side with the CEM. n Overview of features...

Transponder-coded safety systems CEM n Different coding levels U nicode: Each CEM actuator features transponder coding that significantly surpasses the requirement in the EN ISO 14119 standard for a type 4 switch with a high coding level. The actuator’s transponder code is unambiguously assigned to the safety switch by means of a teach-in operation. This effectively prevents the guard from being bypassed using an identical actuator. The requirement in the standard for effective protection against tampering is also met in this way. If necessary, a new actuator can be taught in at any time. M...

n EM-A: System with external evaluation C External evaluation of signals in the control cabinet The guard locking solenoid with the read coil is accommodated in a housing (read head). The actuator’s transponder signals are read by the read coil and forwarded to a CES evaluation unit in the control cabinet (external evaluation). Up to four CEM-A read heads can be connected to a CES evaluation unit. n EM-C60: Variable system with internal evaluation C Internal evaluation of signals in an individually selected switch The system consists only of an actuator and a guard locking solenoid. The...

CEM-A – Systems with external evaluation External evaluation of signals in the control cabinet With external evaluation of the transponder signals, the evaluation electronics are accommodated in a separate housing in the control cabinet. Up to four CEM-A devices or additional read heads from EUCHNER can be connected to the CES evaluation unit and evaluated. The wiring work is minimal, because each read head can be connected to the evaluation unit via only two flexible wires. n CES-AZ evaluation units CES evaluation units combine transponder evaluation with a safety relay in a single device....

CEM-C60 – Variable systems with internal Internal evaluation of signals in an individually selected switch This system offers guard locking for process protection in a modular design. It consists of a CEM actuator and a CEM-C60 guard locking solenoid that prevents safety doors from opening unintentionally. The guard locking solenoid is combined with a safety switch for reliable detection of the door position. The safety switch with integrated read coil and evaluation electronics can be selected as required and is mounted on the guard locking solenoid. The CEM-C60 can be combined with the...

CEM-C40 – Safety switch with internal Internal evaluation of signals in the safety switch With internal evaluation, the evaluation electronics and read coil are accommodated in the same housing (safety switch). The switches feature pulsed safety outputs (semiconductor, OSSD) to detect short circuits in the connecting cables. The outputs on the safety switch can be connected to decentral peripheral devices or directly to safe control systems. On the activation of the guard locking, the device checks whether the locking force is at least 400 N. If the locking force is greater than 400 N, the...
