| transmissive sensor hoa0825 description features phototransistor output four mounting configurations 0.165 in.(4.2 mm) slot width the hoa0825 series consists of an infrared emitting diode facing an npn silicon phototransistor encased in a black thermoplastic housing. a slot in the housing between emitter and detector provides the means for mechanically interrupting the emitter beam. the phototransistor switching takes place whenever an opaque object passes through the slot between emitter and detector. the hoa0825 series employs plastic molded components. for additional component information see sep8506 and sdp8406. housing material is polycarbonate. housings are soluble in chlorinated hydrocarbons and ketones. recommended cleaning agents are methanol and isopropanol. infra-52.tif outline dimensions in inches (mm) 3 plc decimals 0.010(0.25) tolerance 2 plc decimals 0.020(0.51) .125(3.2) dia typ. a k e c tab #1 { notch indicates collector .406(10.29) .406(10.31) .680(17.27) .690(17.53) .105(2.67) .115(2.92) .250(6.35) .125(3.18) .120(3.06) .095(2.41) .105(2.67) .900(22.86) .300(7.62) .160(4.06) .170(4.32) .125(3.18) ~ ~ ~ ~ tab #2 } optical c l .415(10.54) .425(10.80) dim_040.ds4 hoa0825-003 .415(10.54) .425(10.80) .450(11.43) .450(11.43) .450(11.43) HOA0825-001 hoa0825-002 hoa0825-004 .660(16.76) .660(16.76) dim_40b.ds4 ? honeywell reserves the right to make changes in order to improve design and supply the best products possible. h 270
