Safety Switches

Safety switches monitor doors, gates, and other movable physical guards that separate personnel from a hazard. They will send a signal to the machine control system if the guard has been opened, removed, or out of position.

  1. SI-RF Series safety switches utilize RFID technology to monitor doors, gates, and other mechanical safeguards. They will send a signal to the machine control system to prevent or stop hazardous situations when the guard is not in the proper position.

  2. SI-MAG Series non-contact magnetic switches are a cost-effective solution minimizing device wear and tear, even in applications with persistent use.

  3. Hinge style safety interlock switches have a built-in hinged lever actuator that mounts to a hinged door or flap to detect it is being opened.

  4. Guard locking safety switches prevent access to an area by remaining locked together until the hazardous motion has come to a complete stop.

  5. Small, compact safety interlock switches with metal housing are available in limit switch and trumpet styles, with a choice of actuators.

  6. Small, compact safety interlock switches with plastic housing are available in limit switch and trumpet styles, with a choice of actuators.

  7. Safety limit switches mount directly to a machine and are actuated by the presence or movement of a mechanical machine guard.
