Electro-mechanical safety switches

Your Benefits

  • High availability and safety due to the cone shaped alignment aid
  • High retaining force offers machine reliability, even when exposed to shock and vibration
  • Flexible electrical connectivity due to three cable entry glands
  • Flexi Loop now enables a safe series connection with enhanced diagnostics capabilities and minimal wiring effort.


Safety switches with a separate actuator are made up of two parts: a safety switch that is mounted on the fixed part and an actuator that is mounted on the mobile part of the guard. When the guard is closed, the actuator is moved into the safety switch. This achieves the safe status and the safety-relevant contacts are closed. These devices are ideal for protecting sliding and rotating doors, as well as removable protective covers. The i16S safety switch with a separate actuator has a high locking force that is resistant to shocks and vibrations, which increases machine availability.
