DESCRIPTION
The HOA1885 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1885- 011, - 012) or photodarlington
(HOA1885- 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. The high profile package raises the
optical centerline to a nominal height of 0.063 in.(16.0
mm) from the mounting plane. This is a significant
feature for applications in which surrounding
components might interfere with the interrupting
element if the optical centerline were lower. Detector
switching takes place whenever an opaque object
passes through the slot between emitter and detector.
The HOA1885 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.
