HEDS-5500 Overview

Quick Assembly Two and Three Channel Optical Encoders

HEDM-55xx/560x & HEDS-55xx/56xx
Quick Assembly Two and Three Channel Optical Encoders
Data Sheet
HEDM-55xx/560x HEDS-550x/554x, HEDS-560x/564x
Description
The HEDS-5500/5540, HEDS-5600/5640, HEDM-5500/5540
and HEDM-5600 are high performance, low cost, two
and three channel optical incremental encoders. These
encoders emphasize high reliability, high resolution, and
easy assembly.
Each encoder contains a lensed LED source, an integrated
circuit with detectors and output circuitry, and a codewheel
which rotates between the emitter and detector IC. The
outputs of the HEDS-5500/5600 and HEDM-5500/ 5600
are two square waves in quadrature. The HEDS-5540/5640
and HEDM-5540 also have a third channel index output in
addition to the two channel quadrature. This index output
is a 90 electrical degree, high true index pulse which is
generated once for each full rotation of the codewheel.
The HEDS series utilizes metal codewheels, while the
HEDM series utilizes a film codewheel allowing for resolu-
tions to 1024 CPR.
These encoders may be quickly and easily mounted to a
motor. For larger diameter motors, the HEDM-5600, and
HEDS-5600/5640 feature external mounting ears.
The quadrature signals and the index pulse are accessed
through five 0.025 inch square pins located on 0.1 inch
centers.
Standard resolutions between 96 and 1024 counts per
revolution are presently available. Consult local Avago
sales representatives for other resolutions.

Applications
The HEDS-5500, 5540, 5600, 5640, and the HEDM-5500,
5540,5600 provide motion detection at a low cost, making
them ideal for high volume applications. Typical applica-
tions 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 representa-
tive if more clarification is needed.
