HOA1874 Transmissive Sensor FEATURES • Choice of phototransistor or photodarlington output • Three sensitivity ranges • Choice of metal can package or plastic molded components • 0.120 in.(3.05 mm) slot width INFRA-15.TIF DESCRIPTION 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. OUTLINE DIMENSIONS in inches (mm) Tolerance 3 plc decimals ±0.010(0.25) 2 plc decimals ±0.020(0.51) 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.
