The HOA1883 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1883-011, -012)or photodarlington (HOA1883-013)encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The HOA1883 series employs plastic molded components. For additional component information see SEP8506, SDP8406, and SDP8106.
Housing material is IR transmissive polysulfone. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
