Banner Engineering SI-HG80DQD Hinge Safety Interlock Switch

SI-HG80DQD is Banner Engineering's hinge-style safety interlock switch with a zinc alloy die-cast housing and an inline M12 quick-disconnect. It provides a SPDT safety contact (1 NC/1 NO) through a 4-pin M12 QD and offers a 180-degree hinge range in a compact 97 x 72 x 19 mm enclosure, with an IP67 washdown rating and an operating temperature range of -25 to 70 C. Engineered for rugged machine guarding, it carries Safety Category 4 and SIL CL 3 ratings, with SISTEMA B10d = 2 million and a mechanical life of 1 million cycles. For proper Cat 4 safety, Banner recommends using two switches on a single interlock guard with a two-channel safety module, while its uncoded switch point positioning is set once at installation; typical applications include guarding access doors and gates on automated equipment where opening the guard must stop hazardous motion.
