  • ATEX version
  • With protective plate
  • Suitable for use in zones 2 and 22 (gases and dusts)
  • Safety switches as interlocking device of type 4
  • Safety switch with integrated evaluation electronics
  • Possible to switch pulsed signals
  • Two safety outputs (semiconductor outputs)
  • Up to category 4/PL e according to EN ISO 13849-1
Approach directionCan be adjusted in 90° steps Protective plateA protective plate included protects the safety switch against impacts on the housing and the ingress of a potentially explosive atmosphere. Each actuator is unique. The evaluation unit detects only the actuator that has been taught-in. Additional actuators can be taught in. Category according to EN ISO 13849-1Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

Attention:The operating distance may vary depending on the background material and installation situation. (Only in combination with actuator CES-A-BBA, CES-A-BCA) Typical operating distance 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. (Only in combination with actuator CES-A-BPA) Typical operating distance 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.
