Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The HOA1882 series employs an IR transmissive housing which features smooth optical faces without external aperture openings; this feature is desirable when aperture blockage from airborne contaminants is a possibility. The HOA1882 series employs plastic molded components. For additional component information see SEP8506/8706, SDP8406, and SDP8106. .150(3.81) Housing material is IR transmissive polysulfone. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol. .050(1.27) .050(1.27) .100(2.54) .300(7.62) MIN DIM_053.cdr 318 h Honeywell reserves the right to make changes in order to improve design and supply the best products possible.
