  • Safety switch with integrated evaluation electronics
  • No series connection
  • Short circuit monitoring
  • 2 safety outputs (semiconductor outputs)
  • Category 4/PL e according to EN ISO 13849-1
  • M12 plug connector 5-pin
  • Multicode
Approach direction Can be adjusted in 90° steps 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

Typical operating distances With actuator CES-A-BBA and CES-A-BCA For a side approach direction for the actuator and safety switch, a minimum distance of s = 4 mm must be maintained so that the operating distance of the side lobes is not entered. With actuator CES-A-BPA 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. With actuator CES-A-BRN 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.
