High Bay Occupancy Sensor Lenses
HB-L1 and HB-L1M:
Ideal for high ceiling aisleway applications
Both are multi-cell, multi-tier Fresnel lenses
60’ x 20’ HB-L1 coverage when mounted at 40’ height
30’ x 20’ HB-L1M coverage when mounted at 40’ height
The High Bay (HB) Occupancy Sensor Modules (sold separately) require one of four available lenses to operate: the HB-L1, HB-L1M, HB-L3 or HB-L4. 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.
HB-L1 and HB-L1M
The HB-L1 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 HB-L1, the HB-L1M 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.
HBL1 Coverage: 60' x 20' area at 40' height
HBL1M Coverage: 30' x 20' area at 40' height
