Electro-mechanical safety switches

Your Benefits

  • Standard device design provides quick and easy mounting
  • Rugged metal housing provides increased machine reliability, even when the guard has a mechanical offset
  • High availability and safety due to the cone shaped alignment aid
  • Improved diagnostics due to additional signaling contacts
  • 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 i110S safety switch with a separate actuator has a rugged housing that enables optimal protection against external influences, ensuring high machine reliability.
