Data Sheet
Description
The HEDS-65xx/HEDL-65xx are high performance
two and three channel optical incremental encoders.
These encoders emphasize high reliability, high
resolution, and easy assembly. Each encoder contains a
lensed LED source (emitter), an integrated circuit with
detectors and output circuitry, and a codewheel which
rotates between the emitter and detector integrated
circuit. The outputs of the HEDS-6500 are two single
ended square waves in quadrature. The HEDL-65xx
outputs are differential.
The HEDS-6540 / HEDL-6540 also have a third channel
index output in addition to the two quadrature outputs.
This index is an active high pulse that occurs once ev-
ery full rotation of the codewheel. Resolutions up to 1024
Counts Per Revolution are available in the two and three
channel versions.
The line driver option offers enhanced performance
when the encoder is used in noisy environments, or
when it is required to drive long distances.
The line driver option utilizes an industry standard line
driver IC AM26C31Q which provides complementary
outputs for each encoder channel. Thus the outputs
of the line driver encoder are A and
are 26C32 and 26C33.
The quadrature signals are accessed through a cable
and 10-pin female connector. Please refer to the or-
dering information at the end of this data sheet for a
selection matrix.

Features
• Two channel quadrature output with optional
• TTL compatible single ended outputs on HEDS Series
• 100ºC operating temperature for metal code wheel
• 70°C operating temperature for mylar code wheel
• Industry standard AM26C31Q CMOS line driver IC on
• Easy assembly, no signal adjustment necessary
• Resolutions up to 2048 counts per revolution
Applications
The HEDS-65xx / HEDL-65xx provide motion de-
tection to a very high resolution and accept a
variety of shaft sizes up to a maximum of 5/8 inches.
Typical applications include printers, plotters, tape
drives, positioning tables, and automatic handlers.
Note: Avago Technologies encoders are not recommend-
ed for use in safety critical applications. Eg. ABS braking
systems, power steering, life support systems and critical
care medical equipment. Please contact sales represen-
tative if more clarification is needed.
