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

Description
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.
