WATT STOPPER HBL3 Lens high bay occupancy sensor white 24' dia

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 HBL3 Lens offers 360° coverage and is best suited for open area and aisleway coverage in high bay applications. The HBL3 is a multi-cell, multitier Fresnel lens offering a high density coverage pattern that spreads over a 24’ diameter area at a height of 20’.
