DESCRIPTION
The HOA1886 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1886- 011, - 012) or photodarlington
(HOA1886- 013) encased in a black thermoplastic
housing with IR transmissive inserts which form the
optical windows. This arrangement provides excellent
protection against ambient light while eliminating
aperture openings which could be clogged by airborne
contaminants. Detector switching takes place whenever
an opaque object passes through the slot between
emitter and detector. The HOA1886 series employs
plastic molded components and has a 0.050 in.(1.27
mm) x 0.060 in.(1.52 mm) vertical aperture in front of
the detector. For additional component information see
SEP8506/8706, SDP8406, and SDP8106.
Housing material is polycarbonate. Housings are
soluble in chlorinated hydrocarbons and ketones.
Recommended cleaning agents are methanol and
isopropanol.
