WATT STOPPER HBL1 Lens high bay occupancy sensor white 60x20'

The High Bay (HB) Occupancy Sensor Modules (sold separately) require one of four available lenses to operate: the HBL1, HBL1M, HBL3 or HBL4. Each Fresnel lens is designed for a different application, allowing for use at different mounting heights and locations. Each HB sensor lens snapmounts to any module, and can be interchanged by simply un-snapping and re-snapping the ideal lens for the particular application. They can also be repositioned 90° on the sensor. The HBL1 Lens offers linear patterns best suited for high bay aisleway applications. The Fresnel lens is designed to detect walking motion when mounted at or around 40’. In optimal conditions, the lens has a 60’ linear detection range. Identical to the HBL1, the HBL1M comes with opaque adhesive tape applied to the interior of the lens, cutting off 1/2 of the coverage pattern. This customized coverage is ideal for the beginning of aisle ways where cross traffic could be an issue.
