HOA1874 Series Transmissive Sensor, Darlington Output, Plastic Package The HOA1874 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1874-001, -002, -011, -012) or photodarlington (HOA1874-003, -013) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The HOA1874-001, -002 and -003 have a 0.050 in (1.27 mm) dia. detector aperture and employ metal can packaged components while the HOA1874-011, -012, and -013 have a 0.060 in (1.52 mm) dia. detector aperture and contain plastic molded components. For additional component information see SE1450, SD1440, SD1410, SEP8506, SDP8406, and SDP8106. HOA1874-001, 002, 003 housing material is acetal copolymer. HOA1874-011, 012, 013 housing material is polyester. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
