SI-HG63 Hinge Style Switches


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).
