Safety-switch-CTP-AP Your advantages Safety switch with guard locking and safe guard lock monitoring Integrated CES-AP electronics A special evaluation unit is not required Safety category 4 and PL e according to EN ISO 13849-1 Compatible mounting with existing safety switches The safety switch CTP combines the proven principle of operation of electromechanical safety switches with guard locking and modern transponder coded safety engineering. Thanks to the transponder technology, even a single CTP achieves category 4 / PL e according to EN ISO 13849-1, without additional fault exclusion, and meets all the requirements of EN ISO 14119. It is ideally suited to applications in which a high Performance Level and a locking force of up to 2600 N are required. More information Versatile use The CTP reliably secures safety doors and flaps on machines and systems. Thanks to the integrated guard locking and guard lock monitoring it can be used both for process protection and the protection of personnel. Its slender design permits space-saving mounting on the safety guard. With a guard locking force of 2600 N the CTP effectively prevents the opening of safety doors. The very robust plastic housing with metal head as well as the high degree of protection IP 67 / IP 69 make the CTP the all-rounder for almost every industrial usage. The CTP is suitable even for harsh, dirty environments. Mounting and principle of operation The CTP consists of two components, a safety switch and a separate actuator. The safety switch is mounted on the fixed part of the safety guard, the actuator on the movable part. The CTP can be approached from four directions. For improved insertion of the actuator, the head is equipped with an integrated funnel. This feature is particularly advantageous on unstable door designs as well as if the door is incorrectly adjusted. When the safety guard is closed, the actuator moves into the head on the safety switch. The safety outputs are switched on if the integrated transponder chip EUCHNER -

Safety-switch-CTP-AS Your advantages Integrated AS-i connection Robust housing with degree of protection IP 67/IP 69 Narrow design Locking force 2,600ÊN Comprehensive, detailed diagnostics option Compatible mounting with existing electromechanical safety switches Design and functionality The CTP-AS can be operated directly on the AS-i bus and provides the control system with both the door position and information about the locking position. Information about a possible malfunction in the switch can also be diagnosed directly in the control system. Operation on all known AS-i safety monitors in the proven manner is a matter of course. It is possible to change from an electromechanical safety switch to the CTP in PL e without modifying the software on the monitor. EUCHNER -
Safety-switch-CET-AP Your advantages Safety switch with guard locking and safe guard lock monitoring Integrated CES-AP electronics A special evaluation unit is not required Safety Category 4 and PL e according to EN ISO 13849-1 in case of horizontal mounting, or head downward Two safe semiconductor outputs and monitoring output OUT Safety outputs with pulsing Input (optional) for the connection of feedback loop and start button Design and functionality The CET-AP-É forms a complete safety solution (PL e according to EN ISO 13849-1). Depending on the version a start button and feedback loop can be connected. As a result the CET-AP-É includes everything that is necessary to secure a safety guard. It could not be easier! More information 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 state. Connection to decentralized peripheral systems (e.g. ET200pro) Series CET-AP-...-SI-... switches (2x plug connectors M12) have a special pin assignment that makes possible direct connection to decentralized peripheral systems, e.g. Siemens ET200pro. OUT output 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. The OUT outputs on the individual switches can, however, not be polled if connected in series using a Y-distributor. Evaluation is only possible on parallel wiring to the control cabinet. RST input The switches in a chain in a fault state can be reset using the RST input. To do this, a voltage of 24 V is appli EUCHNER -

Safety-switches-CEM-AY-C40 Your advantages Safety switch with integrated solenoid for process protection (without guard locking monitoring) Integrated CES-AY electronics A special evaluation unit is not required Safety category 4 and PL e according to EN ISO 13849-1 for the door position monitoring Design and functionality The CEM safety switches have, in addition to the transponder, a solenoid for holding the safety guard in the locked position. It offers a series of functional and safety-related advantages, because the guard locking principle is realized by the direct action of electromagnetic force between the switch and actuator. With this type there are no longer any protruding parts and therefore no risk of injury. The devices have no insertion openings for actuators in which dust can collect. The anchor plate for the CEM actuator has spring mountings and can be tilted up to an angle of +/-4¡. Therefore, when a maladjusted safety door is closed, the CEM actuator automatically adjusts itself to the surface of the solenoid. Subsequent adjustment of the safety door is no longer necessary. Even with a center offset of 5 mm (anchor plate in relation to solenoid) the full locking force is achieved. EUCHNER -

AR-Evaluation-Unit Your advantages Quick overview of the status of each switch in the chain Safety relay already integrated Reduced wiring effort due to AR technology Easy to service due to plug-in connection terminals Design and functionality Using the AR evaluation unit AR switch chains with up to 12 devices can be evaluated. All relevant status information on the switches connected is routed to the evaluation unit using only two inputs. The four safety outputs are switched depending on these input signals. Connected parts of the safety circuit, e.g. contactors, can be monitored via a feedback loop. The system can be started either manually using a start button or automatically. With a total of 14 monitoring outputs, the CES-AR-AES supplies downstream control systems with information on the switching state, as well as any diagnostic messages present.
