HOA2003-001

The HOA2003 series Optoschmitt Sensor 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 10kR (nominal) pull-up 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 0.01-inch (0.254mm) x 0.04-inch (1.02mm) vertical aperture which is ideal for use in applications in which maximum position resolution is desired. The series employs plastic molded components. Housing material is polysulfone. Housings are soluble in chlorinated hydrocarbons and ketones.
