HOA1884 Transmissive Sensor FEATURES • Choice of phototransistor or photodarlington output • Side mount package • Accurate position sensing • 0.125 in.(3.18 mm) slot width INFRA-75.TIF DESCRIPTION The HOA1884 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1884- 011, - 012) or photodarlington (HOA1884- 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 0.020 in.(.508 mm) x 0.040 in.(1.02 mm) vertical aperture. The HOA1884 series employs plastic molded components. For additional component information see SEP8506, SDP8406, and SDP8106.
