Description
Features
The AEDR-8320 encoder is an analog output encoder
that employs optical reflective technology for rotary and
linear movement control.
With the introduction of reflective technology, encoder
packages can now be made smaller and weigh signifi-
cantly lighter. This statement is better reflected in the
ability of the AEDR-8320 encoder which can easily fit into
many space and weight constraint applications, e.g., CD
or DVD writer laser head’s linear movement.
The AEDR-8320 comes in a 180 LPI (Lines Per Inch) or
7.09 mm lines per mm. In addition its 2-channel analog
outputs can obtain higher resolution through interpola-
tion of 2x, 4x, 8x or more. For example, with 8x interpola-
tion, the final resolution of the encoder will yield 1,440
lines per inch, which is approximately 20 µm accuracy.
AEDR-8320 encoder enhances design flexibility and pro-
vides an easy-to-assemble solution to a wide variety of
applications, while continuously ensuring reliability in
performance.
