The HOA1406 series consists of an infrared emitting
diode facing an NPN silicon phototransistor
(HOA1406-001) or photodarlington (HOA1406-003)
encased side-by-side on converging optical axes, in a
black thermoplastic housing. The detector responds to
radiation from the IRED only when a reflective object
passes within its field of view. This low profile sensor is
ideally suited for applications where space is limited, or
stacking of sensors is required. The HOA1406 series
employs hermetically sealed metal can packaged
components. For additional component information see
SE2460, SD2440, SD2410.
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:
IRED anode - red
IRED cathode - black
Collector - white
Emitter - green
