Manufacturer Part # : Safety-switch-CES-AH
Manufacturer : EUCHNER
Description : Read head and evaluation electronics integrated in one housing Semiconductor output Safety outputs for directly switching up to 4 A Connection of the safety circuit using M23 plug connector Reading and evaluating directly on site The compact safety switches in the system family CES-AÉ combine read head and evaluation unit in one housing. The switches have two safety outputs and one monitoring output. All outputs are semiconductor outputs. More information Non-contact safety switch CES-AH Functional description The Coded Electronic Safety switch CES consists of two components: Coded actuator Evaluation unit / read head In the case of the devices described in this section the read head and the evaluation electronics are integrated in one housing. 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. Devices in the system family CES-AH-... have special safety outputs that are suitable for the direct switching of large loads. In appropriate applications it is therefore not necessary to connect power relays or contactors in between. The information on 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 50 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 w
