Output
The HEDS-9000 and the HEDS-
9100 series are high performance,
low cost, optical incremental
encoder modules. When used with
a codewheel, these modules
detect rotary position. The
modules consist of a lensed (LED)
source and a detector IC enclosed
in a small C-shaped plastic
package. Due to a highly col-
limated light source and unique
photodetector array, these
inch square pins located on 0.1
inch centers.
modules are extremely tolerant to
mounting misalignment.
• TTL Compatible
• Single 5 V Supply
Standard resolutions for the
HEDS-9000 are 500 CPR and
1000 CPR for use with a HEDS-
6100 codewheel or equivalent.
The two channel digital outputs
and the single 5 V supply input
are accessed through five 0.025

Block Diagram
Applications
The HEDS-9000 and 9100
provide sophisticated motion
detection at a low cost, making
them ideal for high volume
applications. Typical applications
include printers, plotters, tape
drives, and factory automation
equipment.
Note: Agilent Technologies
encoders are not recommended
for use in safety critical
applications. Eg. ABS braking
systems, power steering, life
support systems and critical care
medical equipment. Please
contact sales representative if
more clarification is needed.
Output Waveforms
Theory of Operation
The HEDS-9000 and 9100 are C-
shaped emitter/detector modules.
Coupled with a codewheel, they
translate the rotary motion of a
shaft into a two-channel digital
output.
As seen in the block diagram,
each module contains a single
Light Emitting Diode (LED) as its
light source. The light is
collimated into a parallel beam by
means of a single polycarbonate
lens located directly over the
LED. Opposite the emitter is the
integrated detector circuit. This
IC consists of multiple sets of
photodetectors and the signal
processing circuitry necessary to
product the digital waveforms.
by the pattern of spaces and bars
on the codewheel. The
outputs are then fed through the
signal processing circuitry
photodiodes which detect these
interruptions are arranged in a
pattern that corresponds to the
radius and design of the ode-
wheel. These detectors are also
spaced such that a light period on
one pair of detectors corresponds
to a dark period on the adjacent
pair of detectors. The photodiode
resulting in A, A, B, and B. Two
comparators receive these signals
and produce the final outputs for
channels A and B. Due to this
integrated phasing technique, the
digital output of channel A is in
quadrature with that of channel B
(90 degrees out of phase).
The codewheel rotates between
the emitter and detector, causing
the light beam to be interrupted

Direction of Rotation: When the
codewheel rotates in the direction

channel B will lead channel A.

is nominally 180°e or 1/2 cycle.
State Width Error (∆S): The

Pulse Width Error (∆P): The

Derating Curves over Extended Operating Frequencies (HEDS-9000/9100)
Below are the derating curves for state, duty, phase and VOH over extended operating frequencies of up to
240 kHz (recommended maximum frequency is 100 kHz). The curves were derived using standard TTL load.
–40°C operation is not feasible above 160 kHz because VOH will drop below 2.4 V (the minmum TTL for logic
state high) beyond that frequency.
