DESCRIPTION
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.
