DESCRIPTION
The HOA1870 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1870- 031) or photodarlington (HOA1870- 033)
encased in a black thermoplastic housing. Detector
switching takes place whenever an opaque object
passes through the slot between emitter and detector. A
minimum of 18.0 in.(457 mm) lead wires provides
alternate electrical connection when PC board mounting
is not possible. This device is ideal for use in
applications in which maximum position resolution is
desired. Both emitter and detector have a 0.006
in.(0.152 mm) x 0.040 in.(1.02 mm) vertical aperture.
The HOA1870 series employs plastic molded
components. For additional component information see
SEP8506, SDP8406 and SDP8106.
Housing material is polycarbonate. Housings are
soluble in chlorinated hydrocarbons and ketones.
Recommended cleaning agents are methanol and
isopropanol.
Wire color code and functions are:
Orange - IRED Anode
White - Detector Collector
Green - IRED Cathode
Blue - Detector Emitter
