The HOA1888 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1888-011)or photodarlington (HOA1888-013)encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. Both emitter and detector have 0.060 in (1.52 mm) x 0.060 in (1.52 mm) vertical apertures.
The sensor housing contains IR (Infrared) transmissive optical windows. This arrangement provides excellent protection against visible ambient light while eliminating aperture openings which could be clogged by airborne contaminants.
Housing material is polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
