SI-LS & SI-QM100 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.

• Achieves Cat 4, PL e, or SIL CL 3 safety ratings with a single swicth deployed on a guard
• 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
