The HOA1873 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1873-001, -002, -011, -012) or photodarlington
(HOA1873-003, -013) encased in a black thermoplastic
housing. Detector switching takes place whenever an
opaque object passes through the slot between emitter
and detector. The HOA1873-001, -002, and -003 have
a 0.050 in.(1.27 mm) dia. detector aperture and employ
metal can packaged components, while the
HOA1873-011, -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.
HOA1873-001, 002, 003 housing material is acetal
copolymer. HOA1873-011, 012, 013 housing material is
polyester. Housings are soluble in chlorinated
hydrocarbons and ketones. Recommended cleaning
agents are methanol and isopropanol.
