The HB300, HB330, HB340, HB350, HB340B, and HB350B sensors control lighting in high mount areas. The sensors turn lights on and off basedon occupancy, and install directly to industrial T5 or T8 fixtures via surface mount, a snap in connector which mounts through a half inch knockout with 18 inches leads to the back box, or optional Extender Module. The modular lenses required to operate ordered separately are specially designed to provide reliable coverage from a wide range of mounting heights.
