HOA2001 Transmissive Optoschmitt Sensor FEATURES • Direct TTL interface • Buffer logic • 0.060 in.(1.52 mm) dia. detector aperture • 0.120 in.(3.05 mm) slot width • 0.050 in.(1.27) offset pin circle detector eads INFRA-45.TIF DESCRIPTION The HOA2001 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 HOA2001 employs plastic molded components. For additional component information see SEP8506 and SDP8600. OUTLINE DIMENSIONS in inches (mm) Tolerance 3 plc decimals ±0.010(0.25) 2 plc decimals ±0.020(0.51) Housing material is polyester. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
