HOA1870 Transmissive Sensor FEATURES • Choice of phototransistor or photodarlington output • Accurate position sensing • 0.070 in.(1.78 mm) slot width • 18.0 in.(457 mm) min. 22 AWG UL 1007 wire leads INFRA--7.TIF DESCRIPTION OUTLINE DIMENSIONSin inches (mm) The HOA1870 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) (HOA1870 031) or photodarlington (HOA1870 033) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object .285(7.24) .052(1.32) passes through the slot between emitter and detector. A .265(6.73) (2 PLCS) .155(3.94) minimum of 18.0 in.(457 mm) lead wires provides .145(3.68) 45¡ (2 PLCS) .125(3.17) alternate electrical connection when PC board mounting .062(1.58)R OPTICALCL .140(3.56) (2 PLCS) applications in which maximum position resolution is .395(10.03) .130(3.30) desired. Both emitter and detector have a 0.006 .375(9.63) in.(0.152 mm) x 0.040 in.(1.02 mm) vertical aperture. The HOA1870 series employs plastic molded WHT BLU components.
