Theory of Operation
The AEDA-3200 translates rotary motion of a shaft into a
three channel digital output. The AEDA-3200 series has
five key parts: a single light emitting diode (LED) light
source, a photodetector IC with a set of uniquely config-
ured photodiodes, an interpolator IC, a line driver IC and
a pair of lenses.
This light is used to produce internal signals A and A
and B and B

As part of the “push-pull” detector system, these signals
are fed through comparators and line driver that are part
of the signal processing circuitry to produce the final
outputs for channels A.
The AEDA-3200 is available for cycles per revolution (CPR)
of 2500 to 7500. This translates to a maximum resolution
of 30000 counts after quadrature decode (4X).
