Safety-switch-CES-AP Your advantages High protection against tampering Category 4 / PL e according to EN ISO 13849-1 Integrated short circuit monitoring Large operating distance Connection via plug connectors Diagnostics using LED The CES-AP makes transponder technology available to protect even very small guards and doors. The typical CES features such as large read distance and center offset are naturally also offered by the CES-AP. What is more, mounting on profile rails couldn't be easier. Design and functionality The safety switch CES-APÉ has two safety outputs. These outputs are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are therefore not required. More information Indication for actuator in the limit range If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this situation and indicates that the actuator is in the limit range. This allows the safety door to be readjusted in time. Connection to safe control systems or safety relays Do not use a control system or safety relay with pulsing for monitoring short circuits or switch off the pulsing function in these devices. The switch generates its own clock signals on the output lines OA/OB. A downstream device must tolerate these test pulses, which may have a length of up to 0.4 ms. The inputs on the downstream device must be suitable for positive-switching devices (pnp outputs), as the two outputs on the safety switch deliver a level of +24 V in the switched-on state. OUT output (depending on version) The semiconductor output OUT is switched if the safety guard is closed (actuator in the operating distance). It is not allowed to be used for safety functions. DIA output (depending on version) The semiconductor output DIA is switched in the fault state. It is not allowed to be used for safety functions. Reset input EUCHNER -
Safety-switch-CES-AR Your advantages Possible to connect up to 20 safety switches in series Integrated short circuit monitoring by pulsing Large operating distance High protection against tampering Adjustable actuating head with 5 approach directions (only housing C01) Compatible mounting with standard housing according to EN 60947-5-2 (only housing C01) Diagnostics using LED The non-contact safety switch CES-AR-É is designed for systems in which a large number of safety doors need to be monitored. It can also be used as a compact individual switch. The small design of the actuator and switch makes mounting on the safety guard easy. Design and functionality The safety switches are connected together using connectors. The CES-AR-... has two safety outputs. In a chain of switches, the signals from the safety outputs are connected to the next switch. The outputs on the last switch in the chain are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are not allowed (see next section). More information Indication for actuator in the limit range If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this and indicates that the actuator is in the limit range (function available from V 1.1.2 and higher). This allows the safety door to be readjusted in time. Connection to safe control systems or safety relays Do not use a control system or safety relay with pulsing for monitoring short circuits or switch off the pulsing function in these devices. The switch generates its own clock signals on the output lines OA/OB. A downstream device must tolerate these test pulses, which may have a length of up to 1 ms. The inputs on the downstream device must be suitable for positive-switching devices (pnp outputs), as the two outputs on the safety switch deliver a level of +24 V in the switched-on st EUCHNER -

Safety-switch-CES-A-C5-CES-A-W5 Safety switch with integrated evaluation electronics 2 safety outputs (semiconductor outputs) Possible to switch pulsed signals Unicode and multicode switches Connection using M12 plug connector Standard housing according to IEC/EN 60947-5-2, IP 67 Up to Category 4 / PL e according to EN ISO 13849-1 Reading and evaluating directly on site The compact safety switches in the system family CES-A... 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-A-C5.../CES-A-W5.../CES-A-S5... 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 EUCHNER -
