Wide irradiance pattern
Selected to specific on-line intensity
ranges
Low cost, miniature plastic side-
looking package
Mechanically and spectrally matched
to the OP550 series of
phototransistors and the OP560 series
of photodarlingtons
De scrip ion
The OP140 series devices are 935nm
high intensity gallium arsenide infrared
emitting diodes molded in IR
transmissive plastic side-looking
packages. The side looking packages
are for use in PC board mounted slotted
switches or as an easy mount PC board
interrupter.

is a measurement of the average apertured radiant incidence upon a sensing area
0.180" (4.57 mm) in diameter perpendicular to and centered on the mechanical axis of the
lens and 0.653" (16.6 mm) from the lens tip. E
e(APT)
is not necessarily uniform within the
measured area.
