The HOA1872 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1872-001, -002, -011, -012) or photodarlington
(HOA1872-003, -013) encased in a black thermoplastic
housing. Detector switching takes place wherever an
opaque object passes through the slot between emitter
and detector. The HOA1872-001, -002 and -003 have
a 0.050 in.(1.27 mm)dia. detector aperture and employ
metal can packaged components, while the
HOA1872-011, -012, and -013 have a 0.060 in.(1.52
mm) dia. detector aperture and contain plastic molded
components. For additional component information see
SE1450, SD1440, SD1410, SEP8506, SDP8406, and
SDP8106.
Housing material is polyester. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended
cleaning agents are methanol and isopropanol.
