Sensor Switch HMR-50 Line Voltage Passive Infrared Warehouse Sensor

The HMR-50 Series sensor provides Bi-Directional High Bay Aisle Way sensing extending 70 to 110 feet when mounted at heights of 30 to 45 feet. HID Bi-Level or T-5 / T-8 Fluorescent systems can be switched directly using this sensor without the use of power packs. The HMR-50-SH controls Bi-Level HID with a Start-to-High timer, whereas the HMR-50 controls individual fluorescent fixtures. The sensors view pattern provides coverage of the lighting areas of three typically spaced High Bay fixtures. Therefore, when mounted at a fixture, the coverage area extends out to the area that is lighted by the neighboring fixtures. This effect is useful with some Program-Start ballasts that have a delay such that when traveling in a fork-lift truck, lighting needs to be initiated On ahead of the truck. Masking the sensor to cutoff at the end of an aisle is easily done with the enclosed kit. For freezer or high humidity applications, use the HMR-50-LT or HMR-50-SH-LT which allows for cold temperatures or condensing humidity. For total aisle way sensing consider the HMR-10 at each end, and HMR-50s in the center section.
