Safety Limit Switches

SI Series

SI Series safety limit switches combine switch and actuator in one device that mounts directly to a machine. The switch is actuated by the presence or movement of a mechanical machine guard and triggers an output when the guard reaches a user-defined switching point.

  • Four actuator types are available—lever, spindle-mount lever, plunger, and roller
  • 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
  • One-piece switch eliminates need for alignment, engagement and risk of breakage of a separate actuator
  • Design meets positive opening requirements for safety interlocks
  • IEC IP65 rated housing
