Short circuit monitoring The switch generates its own clock signal on the output cables OA/OB. Pay attention to this aspect when connecting to control systems and relays. Multicode evaluation Every suitable actuator is detected by the switch. Category according to EN 13849-1 Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN 13849-1
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated. LED indicator

Approach directions Typical operating distance (Actuator CES-A-BLN... in conjunction with safety switch CES-AR-C.2-... in case of mounting on plastic) For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the operating distance of the side lobes is not entered. Attention: The operating distance may vary depending on the background material and installation situation. Connector assignment
