DESCRIPTION
The HOA088X/089X series consists of an infrared
emitting diode facing an NPN silicon phototransistor
encased in a black thermoplastic housing.
Phototransistor switching takes place whenever an
opaque object passes through the slot between emitter
and detector. This series allows the user to choose from
available options: (1) mounting tab configuration, (2)
detector aperture size, (3) electro-optical
characteristics, and (4) housing materials.
All devices employ a built-in strain relief for maximum
wire attachment strength. The HOA088X series utilizes
an IR transmissive polysulfone housing which features
smooth optical faces without external aperture
openings; this feature is desirable when aperture
blockage from airborne contaminants is a possibility.
The HOA089X series employs an opaque polysulfone
housing with aperture openings for use in applications
in which maximum rejection of ambient light is important
and in situations where maximum position resolution is
desired. The HOA088X/089X series employs plastic
molded components. For additional component
information see SEP8506 and SDP8406.
Housing material is polysulfone. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended
cleaning agents are methanol and isopropanol.
The detector to emitter lead spacing is 0.32 in.(8.13
mm) for all versions. Wire color code and functions are:
Red - IRED Anode
Black - IRED Cathode
White - Detector Collector
Green - Detector Emitter
