HOA1875 Transmissive Sensor FEATURES • Choice of phototransistor or photodarlington output • Low profile package • Wide operating temperature range (- 55¡C to +100¡C) • 0.200 in.(5.08 mm) slot width INFRA-12.TIF DESCRIPTION The HOA1875 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1875- 001, - 002) or photodarlington (HOA1875- 003) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The HOA1875 series has a 0.050 in.(1.27 mm) dia. detector aperture and employs metal can packaged components. For additional component information see SE1450, SD1440, and SD1410. OUTLINE DIMENSIONS in inches (mm) Tolerance 3 plc decimals ±0.010(0.25) 2 plc decimals ±0.020(0.51) Housing material is opaque polysulfone. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
