Locking Style Safety Interlock Switches

SI-LS42 Series

Guard locking safety switches include a machine mounted switch and a guard mounted actuator that prevent access to an area by remaining locked together until the hazardous motion has come to a complete stop.

  • Mechanically coded actuators use two independent operating elements, making it difficult to bypass safety functions
  • Rotating head requires little or no tools to adjust to one of four positions
  • Can be used to prevent access to a hazard, ensure critical processes are not interrupted, or secure material and equipment from theft or tampering
  • Once locked, a machine guard door will not open, eliminating an opportunity for nuisance trips, even if exposed to frequent impact or prolonged vibration
  • IP67-rated safety devices that resist dust, dirt, and some exposure to water and similar environmental challenges
  • Design meets positive opening requirements for safety interlocks
  • Available in power-to-lock and power-to-unlock models with rigid and flexible in-line actuators and a wide range of solenoid voltages
