Description
The HEDS-9040 and HEDS-9140
series are three channel optical
incremental encoder modules.
When used with a codewheel,
these low cost modules detect
rotary position. Each module
consists of a lensed LED source
and a detector IC enclosed in a
small plastic package. Due to a
highly collimated light source and
a unique photodetector array,
these modules provide the same
high performance found in the
HEDS-9000/9100 two channel
encoder family.
