HOA1887 Transmissive Sensor FEATURES  Choice of phototransistor or photodarlington output  Side mount package  Ambient light and dust protective filter  Accurate position sensing  0.010 in.(0.25mm) aperture windows  0.125 in.(3.18 mm) slot width  24.0 in.(610 mm) min. 26 AWG UL 1429 wire leads INFRA-89.TIF DESCRIPTION OUTLINE DIMENSIONSin inches (mm) The HOA1887 series consists of an infrared emitting Tolerance 3 plc decimals ±0.010(0.25) diode facing an NPN silicon phototransistor 2 plc decimals ±0.020(0.51) (HOA1887-011, -012) or photodarlington (HOA1887-013) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The side mounting package is useful in applications in which the interruptive element is parallel to the mounting plane. Both emitter and detector have a 0.010 in.(0.25 mm) x 0.60 in(1.52 mm) vertical aperture. This feature is ideal for use in applications in which maximum position resolution is desired. All devices employ a built-in strain relief for maximum wire attachment strength. The sensor housing contains IR transmissive optical windows. This arrangement provides excellent protection against ambient light while eliminating aperture openings which could be clogged by airborne contaminants. The HOA1887 series contains plastic molded components. For additional component information see SEP8506, SDP8406, and SDP8106. Housing material is polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol. dim_107.CDR Wire color and functions are: Red - IRED Anode Black - IRED Cathode White - Detector Collector h Honeywell reserves the right to make 338 changes in order to improve design and supply the best products possible.
