Description
The HEDS-5500/5540, HEDS-
5600/5640, and HEDM-5500/
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
and 5640 also have a third chan-
nel 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 resolutions to 1024
CPR. The HEDM series is nont
available with a third channel
index.
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 Agilent sales representatives
for other resolutions.
Applications
The HEDS-5500, 5540, 5600,
5640, and the HEDM-5500, 5600
provide motion detection at a low
cost, making them ideal for high
volume applications. Typical
applications include printers,
plotters, tape drives, positioning
tables, and automatic handlers.
ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC DISCHARGE.
