HOA2003-001

HOA2003 Transmissive Optoschmitt Sensor FEATURES • Direct TTL interface • Buffer logic • 0.010 in.(2.54 mm) offset detector leads • 0.125 in.(3.18 mm) slot width • Accurate position sensing • Dust protective housing INFRA-42.TIF DESCRIPTION The HOA2003 consists of an infrared emitting diode facing an Optoschmitt detector encased in a black thermoplastic housing. The photodetector consists of a photodiode, amplifier, voltage regulator, Schmitt trigger and an NPN output transistor with 10 kì (nominal) pullup resistor. The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted. The HOA2003 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 detector has a 0.010 in.(.254 mm) x 0.040 in.(1.02 mm) vertical aperture which is ideal for use in applications in which maximum position resolution is desired. The HOA2003 employs plastic molded components. For additional component information see SEP8506 and SDP8600.
