HOA7720/7730 Connectorized Transmissive Optoschmitt Sensor FEATURES • Direct TTL interface • No interface circuits required • Inverting logic • Two device output options • High resolution • 0.118 in.(3.00 mm) slot width DESCRIPTION The HOA7720/7730 Series 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 and Schmitt trigger with two output configurations. The user can choose from available options of totem pole (HOA7720-M22) or open collector (HOA7730-M22) output. The totem pole output is well suited for applications which require fast transition times. The open collector allows the output of the sensor to interface with circuit elements driven by supply voltages other than Vcc supply. The inverting logic provides a high output when the optical path is interrupted, and a low output when the path is clear. The infrared emitting diode is biased internally eliminating the need for any external circuitry. Interconnection is simplified through the use of an integral Molex three pin connector. Both emitter and detector have a 0.020 in.(.508 mm) x 0.070 in.(1.78 mm) vertical aperture. The narrow aperture is ideal for use in applications in which maximum rejection of ambient light is important, and maximum position resolution is desired. The HOA7720/7730 series employ plastic molded components. For additional component information see SEP8506, SDP8014 and SDP8314. Housing material is opaque polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
