Hinge Style Safety Interlock Switches

 
 

  • Three types are available—load-bearing hinge, hinged lever and rotating hinge.
  • Safety switching point can be set anywhere within 0-180° operating range on some styles.
  • One-piece switch eliminates need for alignment, engagement and risk of breakage of a separate actuator.
  • Design meets positive opening requirements for safety interlocks.
 

SI-HG63 Series Safety Interlock Switches Attached to a Load-Bearing Hinge

  • Repositionable safety switch is integrated into a highly robust PBT housing and screwed onto the fine-cast stainless steel or zinc die-cast hinge.
  • Stainless steel model can support an axial and radial load of 1800 N (180 Kg); Zinc die-cast can support 1200 N(120 Kg).
  • Right-hinge, left-hinge, and right-angle hinge models available; switches can also be converted to operate from the opposite side.
  • Switch components are protected from mechanical impact, for superior performance to actuator-activated safety switches; rated IEC IP67.
  • Hinge operates to a full 270° range of motion; safety switching point (guard-closed position) is adjustable over the full 0–270°operating range.
  • When properly interfaced or used with an appropriate controller, two SI-HG63 switches on an individual gate or guard can achieve safety category 4, per ISO 13849-1 (EN 954-1).
 

  • Encapsulated into a load-bearing hinge for a high degree of protection from intentional defeat
  • Concealed components for protection from mechanical impact
  • Constructed of zinc die-cast for resistance to corrosion
  • Set switch point anywhere within 180° operating range
  • Provide Single-Pull Double Throw (SPDT) contacts with one normally closed (NC) and one normally open (NO)
  • Designed to achieve safety category 4, per ISO 13849 when properly interfaced with a controller
 

  • Connects to doors or flaps which open 90° in one direction
  • Features actuator head with 90° increment rotation
  • Available in models with one of these safety output configurations:
    • One normally closed (NC) and one normally open (NO) contact
    • Two normally closed (NC) contacts
  • Provides choice of actuation properties: -90°, 0° or +90°
  • Constructed of rugged glass reinforced thermoplastic with a plated steel actuator
  • Includes hardware adapter for 1/2" - NPT conduit entry point
  • Designed to achieve safety category 4, per ISO 13849 when properly interfaced with a controller
 

  • Connects directly to door hinge with rotating actuator
  • Features actuator head with 90° increment rotation
  • Available in models with one of these safety output configurations:
    • One normally closed (NC) and one normally open (NO) contact
    • Two normally closed (NC) contacts
  • Constructed of rugged glass reinforced thermoplastic with a plated steel actuator
  • Includes hardware adapter for 1/2" - NPT conduit entry point
  • Designed to achieve safety category 4, per ISO 13849 when properly interfaced with a controller
