Contactless safety switches

Non-contact switches with safety function are ideal for applications where precise guidance of the shield is difficult. Non-contact switches with safety function offer the solution with moving safety devices such as doors, flaps, fences or protective covers. When opening a safety device, dangerous machines and machine movements must be stopped. Non-contact switches must prevent the machines from restarting and must not be manipulated or circumvented.

Versions of contactless switches:

  • Electronic safety switches (unique frequency control)
  • Magnetic safety switches
  • Magnetically coded safety switches
  • Coded RFID safety switches

Contactless switch - Unique coded RFID

The non-contact safety switches from ReeR Safety operate on the basis of Magnus RFID sensors. RFID sensors transmit uniquely encoded radio waves, making the system very reliable. The uniquely coded radio waves are difficult to imitate and ensure that the communication transfer of the safety sensors is not sabotage, something that is possible with magnetic sensors. Magnus RFID enables a safety level up to PLe / SIL3. Even when the contactless safety switches are connected in series. This system is safe and reliable thanks to the unique codings. Read more about contactless safety switch with Magnus RFID.

Three coding types: 

  • Unique coding: transmitter and received are permanently linked to each other.
  • Individual coding: Once used and retouched, a coding can not be reused.
  • Encrypted actuator: The receiver is free and not specifically assigned to a transmitter.
