HOA7720/7730 Series Connectorized Transmissive Optoschmitt Sensor DESCRIPTION The HOA7720/7730 Series consists of an infrared emitting The infrared emitting diode is biased internally, eliminating the diode facing an Optoschmitt detector encased in a black need for any external circuitry. Interconnection is simplified thermoplastic housing. The photodetector consists of a through the use of the integral Tyco three-pin connector. photodiode, amplifier, voltage regulator and Schmitt trigger with either of two output configurations: Both the emitter and detector have a 0.508 mm x 1,78 mm Totem pole (HOA7720-M11) [0.020 in x 0,070 in] vertical aperture. The narrow aperture is Open collector (HOA7730-M11) ideal for use in applications in which the maximum rejection of ambient light is important, and the maximum position resolution The totem pole output is well-suited for applications which is desired. require fast transition times. The open collector allows the output of the sensor to interface with circuit elements driven by The HOA7220/7330 series employ plastic molded supply voltages other than Vcc supply. components. Housing material is opaque polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. The inverting logic provides a high output when the optical path Recommended cleaning agents are methanol and isopropanol. is interrupted, and a low output when the path is clear.
