transmissive sensor hoa088x/089x description features phototransistor output four mounting configurations accurate position sensing 0.125 in.(3.18 mm) slot width choice of detector aperture 24.0 in.(610 mm) min. 26 awg ul 1429 wire leads choice of opaque or ir transmissive housings the hoa088x/089x series consists of an infrared emitting diode facing an npn silicon phototransistor encased in a black thermoplastic housing. phototransistor switching takes place whenever an opaque object passes through the slot between emitter and detector. this series allows the user to choose from available options: (1) mounting tab configuration, (2) detector aperture size, (3) electro-optical characteristics, and (4) housing materials. all devices employ a built-in strain relief for maximum wire attachment strength. the hoa088x series utilizes an ir transmissive polysulfone housing which features smooth optical faces without external aperture openings; this feature is desirable when aperture blockage from airborne contaminants is a possibility. the HOA089X series employs an opaque polysulfone housing with aperture openings for use in applications in which maximum rejection of ambient light is important and in situations where maximum position resolution is desired. the hoa088x/089x series employs plastic molded components. for additional component information see sep8506 and sdp8406. housing material is polysulfone. housings are soluble in chlorinated hydrocarbons and ketones. recommended cleaning agents are methanol and isopropanol. the detector to emitter lead spacing is 0.32 in.(8.13 mm) for all versions. wire color code and functions are: red - ired anode white - detector collector black - ired cathode green - detector emitter to specify the complete product characteristics, see part number guide. infra-66.tif outline dimensions in inches (mm) 3 plc decimals 0.010(0.25) tolerance 2 plc decimals 0.020(0.51) dim_042.cdr package t .495(12.57) .475(12.07) .435(11.05) .415(10.54) .435(11.05) .415(10.54) .435(11.05) .415(10.54) .737(18.72) .717(18.21) package n package p package l .737(18.72) .717(18.21) dim_067.ds4 packages n/p/l honeywell reserves the right to make changes in order to improve design and supply the best products possible. h 278
