The HOA2007 series consists of two infrared emitting diodes facing two Optoschmitt detectors encased in a black thermoplastic housing. The photodetector consists of a photodiode, amplifier, voltage regulator, schmitt trigger, and an NPN phototransistor with a 10 kOhm (nominal) pull-up resistor. Detector switching takes place whenever an opaque object passes through the slot between the emitter and the detector. The buffer logic provides a high output when the optical path is clear. The dual channels allow both the speed and the direction of the interrupter to be sensed. Emitters and detectors have a 0.020 in (0.5 mm) vertical aperture. This feature is ideal for use in applications in which high position resolution is desired.

The sensor housing is an opaque thermoplastic with aperture openings for use in applications in which maximum rejection of ambient light is important and maximum position resolution is desired. The HOA2007 series contains plastic molded components. For additional component information see SEP8506 and SDP8601.

Housing material is Valox®. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
