FEATURES
Choice of phototransistor or
photodarlington output
Visible ambient light and dust
protective filter
12 mm (0.47 in.) slot width
Snap-in housing
The HOA1888 Series consists of an infrared emitting diode facing an
NPN silicon phototransistor (HOA1888-011) or photodarlington
(HOA1888-013) encased in a black thermoplastic housing. Detector
switching takes place whenever an opaque object passes through the
slot between emitter and detector. Both emitter and detector have 1,52
mm (0.060 in.) x 1,52 mm (0.060 in.) vertical apertures.
The sensor housing contains IR (Infrared) transmissive optical
windows. This arrangement provides excellent protection against visible
ambient light while eliminating aperture openings which could be
clogged by airborne contaminants.
Housing material is polycarbonate. Housings are soluble in
chlorinated hydrocarbons and ketones. Recommended cleaning agents
are methanol and isopropanol.
