CES-BP safety switch

Benefits for you

  • Safety switches for separate operation
  • Direct connection to IP67 field modules for various decentralized peripheral systems
  • Two safe semiconductor outputs
  • Own pulsing for short circuit monitoring
  • High level of protection against tampering
  • Category 4 / PL e according to EN ISO 13849-1
  • Connection using M12 plug connector
  • Cable lengths up to 200 m possible
  • Diagnostics using LED
The CES-BP makes transponder technology available to protect even very small guards and doors. The small design of the actuator and switch makes mounting on the guard easy.

Design and functionality

The safety switch CES-BP 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.

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 actuating range. 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

The system family BP is intended to be used for separate operation. The devices are particularly suitable for the connection of safety evaluation units and safety control systems that require short test pulses. Some versions have been optimized for direct connection to decentralized peripheral systems, such as the ET200pro series from Siemens. The BP devices generate test pulses on the safety outputs for short circuit monitoring. Due to the little wiring work, BP devices represent a low-cost solution.
