Hinge Wing Safety Interlock Switches
SI-HG63 Series Safety Interlock Switches Attached to a Load-Bearing Hinge
Models
Features
• Safety switch is integrated into a highly robust PBT housing and screwed onto the
fine-cast stainless steel hinge.
• Safety switching point is repositionable.
• Right-hinge, left-hinge, and right-angle hinge models available; switches can also be
converted to operate from the opposite side.
• A non-switching blank hinge is also available (see page 7).
• 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.
• Hinge can support an axial and radial load of 1200 N (120 Kg).
• 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).
• Typical applications include:
– Hinged covers and guards to machines
– Hinged doors and gates in safety fencing systems
– Modular aluminum framing
*NOTE: Terminals 33 and 34 are non-safety.
