SI Series Plunger Style Safety Limit Switches are plunger actuated Type 1 interlocking devices used to monitor the position of a guard, gate, door, or other physical barrier separating an individual from a hazard.  
 
  • Mechanically coded actuators use two independent operating elements to minimize intentional tampering or defeat
  • Rotating head and top or side engagement allows for eight different actuator positions
  • Design meets positive opening requirements for safety interlocks
  • IEC IP65 switch housing rating increases to IEC IP67 with addition of a screw to the wiring chamber door
