The OSFHU installs directly to an industrial fluorescent luminaire or an electrical junction box. It is a self-contained sensor and relay that turns individual light fixtures on or off based on occupancy in the detection zone. It comes with three interchangeable lenses for use in either a 360-degrees high-bay or 360-degrees low-bay general area or an aisle way. The OSFHU provides reliable coverage up to 40 ft. Mounting heights. The OSFHU is also available in a model for cold storage applications with temperatures as low as -40-degrees f. To improve the field-of-view for deep body fixtures, a separate offset adapter accessory (OSFOA-00W) can be used to position the sensor below the fixture body. The adapter simply snaps into a 1/2-inch knockout on the end of the industrial fixture to attach the sensor.
