Minneapolis, MN–Banner Engineering Corp. introduces SI-HG63 Series Hinge Safety Interlock Switches for safeguarding of hazards. SI-HG63 hinge switches are used in place of the standard hinges on swinging guards, gates or doors. They offer two normally closed safety contacts and one normally open auxiliary contact for greater application flexibility. When the SI-HG63 hinge switch is activated, these normally closed safety contacts are forced open by a non-resilient mechanical means (not reliant on springs), interrupting the electrical circuit and sending a stop signal to the machine control. SI-HG63 hinge switches are also repositionable, with a safety switching point that is easily adjustable (±1.5°) throughout the hinge’s full 0-270° range of motion.
Banner’s SI-HG63 hinge switches are built to withstand harsh plant environments, with each safety switch body integrated into a highly robust PBT housing and integrated on to a stainless steel hinge. They are rated IEC IP67 and deliver superior performance and improved protection against defeat over actuator-style safety switches. Each hinge can support an axial and radial load of 1200 N (approximately 120 kg). In addition to in-line QD and “out-the-back” right-angle QD models, right-side and left-side hinges are available, which can be converted to operate from the opposite side when needed. List price for SI-HG63 hinge switches start at $159 each.
Applications. Banner SI-HG63 Series Hinge Safety Interlock Switches offer durable construction and dependable mechanical operation to protect individuals in guard monitoring applications, including:
* Hinged covers and guards on machines
* Safeguarding modular aluminum framing applications
* Doors and gates in safety fencing systems
In addition, several features of the SI-HG63 hinge switch make it particularly easy to set up and use:
* Features two normally closed safety contacts and one normally open auxiliary contact rated
at 3A @ 230V ac 1.0A @ 24V dc
* Comes complete with repositionable safety switch integrated into a robust PBT housing and a rugged fine-cast stainless steel hinge
* Offers right-hinge QD, left-hinge QD, and right-angle QD models and can be converted to
mount from the opposite side
* Provides IP67 rating, with switch components protected from mechanical impact
* Operates to a full 270° range of motion, with safety switching point (guard-closed position)
adjustable over full operating range (±1.5°)
* Supports an axial and radial load of 1200 N (approximately 120 kg)
* Achieves safety category 4, per ISO 13849-1 (EN 954-1) when two SI-HG63 hinge switches
on an individual guard are properly interfaced or used with an appropriate controller
* Offers a non-switching blank hinge option
