The HOA1882 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1882-011, -012) or photodarlington
(HOA1882-013) encased in a black IR transmissive
thermoplastic housing. Detector switching takes place
whenever an opaque object passes through the slot
between emitter and detector. The HOA1882 series
employs an IR transmissive housing which features
smooth optical faces without external aperture
openings; this feature is desirable when aperture
blockage from airborne contaminants is a possibility.
The HOA1882 series employs plastic molded
components. For additional component information see
SEP8506/8706, SDP8406, and SDP8106.
Housing material is IR transmissive polysulfone.
Housings are soluble in chlorinated hydrocarbons and
ketones. Recommended cleaning agents are methanol
and isopropanol.
