  • 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
