Functional description The Coded Electronic Safety switch CES consists of two components: Coded actuator Evaluation unit / read head The evaluation unit described in this section is integrated with the read head in a standard housing according to IEC/EN 60947-5-2. Thanks to the high degree of protection IP67, this switch can be used directly on the safety guard in a very harsh environment. Semiconductor technology allows for a compact design of the evaluation unit and wear-free switching with a theoretically unlimited number of operating cycles. The information from the coded actuator is read by the evaluation unit and processed at the same point. The transfer of static signals (information on whether door open or closed) to the higher-level switchgear permits the use of connecting cables up to 300 m long with the system. Serial wiring, i.e. the cascading of several evaluation units, is possible. This feature makes it possible for you to implement decentralized wiring concepts with the safety switch CES. Specifically, the major advantage of the system is that the positioning of the evaluation unit directly at the safety guard saves space in the control cabinet. The system operator can read the current state of the safety switch on the two LED displays (one with double function). If the actuator is in the operating distance, the OUT LED illumin
