HEDx-9xx1 Option
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 detec-
tor 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.

Theory of Operation
The HEDS-9040 and 9140 are emitter/detector modules.
Coupled with a codewheel, these modules translate the
rotary motion of a shaft into a three-channel digital out-
put.
As seen in the block diagram, the modules contain a
single Light Emitting Diode (LED) as its light source. The
light is collimated into a parallel beam by means of a
single poly car bon ate lens located directly over the LED.
Opposite the emitter is the integrated detector circuit.
This IC consists of multiple sets of photodetec tors and
the signal processing circuitry necessary to produce the
digital waveforms.
The codewheel rotates between the emitter and detector,
causing the light beam to be interrupted by the pattern
of spaces and bars on the code wheel. The photo diodes
which detect these interrup tions are arranged in a pat-
tern that corresponds to the radius and design of the
code 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 photo-
diode outputs are then fed through the signal process-
ing circuitry resulting in A, A, B, B, I and I. Comparators
receive these signals and produce the nal outputs for
channels A and B. Due to this integrated phasing tech-
nique, the digital output of channel A is in quadrature
with that of channel B (90 degrees out of phase).
The output of the comparator for I and I is sent to the in-
dex processing circuitry along with the outputs of chan-
nels A and B. The nal output of channel I is an index
pulse PO which is generated once for each full rotation of
the codewheel. This output PO is a one state width (nomi-
nally 90 electrical degrees), high true index pulse which
is coincident with the low states of channels A and B.
The HEDS-9040 and 9140 have two channel quadrature
outputs plus a third channel index output. 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-9040 is designed for use with a HEDX-614X
code wheel which has an optical radius of 23.36 mm
(0.920 inch). The HEDS-9140 is designed for use with a
HEDx-5x4x code wheel which has an optical radius of
11.00 mm (0.433 inch).
The quadrature signals and the index pulse are accessed
through ve 0.025 inch square pins located on 0.1 inch
centers.
Standard resolutions between 256 and 2000 counts per
revolu tion are available. Consult local Avago sales repre-
sentatives for other resolutions.
Applications
The HEDS-9040 and 9140 provide sophisticated motion
control detection at a low cost, making them ideal for
high volume applications. Typical applica tions include
printers, plotters, tape drives, and industrial and factory
automation equipment.
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 clarication is needed.

Electrical Interface
To insure reliable encoding performance, the HEDS-9040
and 9140 three channel encoder modules require 2.7
kΩ (±10%) pull-up resistors on output pins 2, 3, and 5
(Channels I, A and B) as shown in Figure 1. These pull-up
resistors should be located as close to the encoder mod-
ule as possible (within 4 feet). Each of the three encoder
module outputs can drive a single TTL load in this con-
guration.
Figure 1. Pull-up Resistors on HEDS-9X40 Encoder Module Outputs.
Mounting Considerations
Figure 2 shows a mounting tolerance requirement for
proper operation of the HEDS-9040 and HEDS-9140. The
Aligning Recess Centers must be located within a toler-
ance circle of 0.005 in. radius from the nominal locations.
This tolerance must be maintained whether the module
is mounted with side A as the mounting plane using
aligning pins (see Figure 5), or mounted with Side B as
the mounting plane using an alignment tool (see Figures
3 and 4).
Figure 2. HEDS-9X40 Mounting Tolerance.

Mounting with an Alignment Tool
The HEDS-8905 and HEDS-8906 alignment tools are rec-
ommended for mounting the modules with Side B as the
mounting plane. The HEDS-8905 is used to mount the
HEDS-9140, and the HEDS-8906 is used to mount the
HEDS-9040. These tools x the module position using
the codewheel hub as a reference. They will not work if
Side A is used as the mounting plane.
The following assembly procedure uses the HEDS-
8905/8906 alignment tool to mount a HEDS-9140/9040
module and a HEDS-5140/6140 codewheel:
Instructions:
1. Place codewheel on shaft.
2. Set codewheel height by placing alignment tool
on motor base (pins facing up) ush up against the
codewheel as shown in Figure 3. Tighten codewheel
setscrew and remove alignment tool.
3. Insert mounting screws through module and thread
into the motor base. Do not tighten screws.
4. Slide alignment tool over codewheel hub and onto
module as shown in Figure 4. The pins of the alignment
tool should t snugly inside the alignment recesses of
the module.
5. While holding alignment tool in place, tighten screws
down to secure module.
6. Remove alignment tool.
Mounting with Aligning Pins
The HEDS-9040 and HEDS-9140 can also be mounted us-
ing aligning pins on the motor base. (Hewlett-Packard
does not provide aligning pins.) For this conguration,
Side A must be used as the mounting plane. The align-
ing recess centers must be located within the 0.005 in. R
Tolerance Circle as explained above. Figure 5 shows the
necessary dimensions.

Mounting with Aligning Pins
The HEDS-9040 and HEDS-9140 can also be mounted
using aligning pins on the motor base. (Avago does not
provide aligning pins.) For this conguration, Side A
must be used as the mounting plane. The aligning recess
centers must be located within the 0.005 in. Radius Tol-
erance Circle as explained in “Mounting Considerations.”

(1000CPR, 11.00mm Rop)
*Please note that the image side of the codewheel must always be facing the module Side A.
The Index area on the HEDS- 9040 Option T00, 2000 CPR
and HEDS-9140 Option B00, 1000 CPR Encoder Module
has a nonsymmetrical pattern as does the mating Code-
wheel. In order for the Index to operate, the “Rightread-
ing” side of the Codewheel disk (the “Artwork Side”) must
point toward “Side A” of the Module (the side with the
connecting pins).
Because the Encoder Module may be used with either
“Side A” or with “Side B” toward the
Mounting Surface, Avago supplies two versions of Film
Codewheels for use with the Option T00 3-channel
Module and Option B00 3-Channel Module: Codewheel
HEDM-6140 Option TXX and HEDM-5040 Option Bxx has
the Artwork Side on the “Hub Side” of the Codewheel/
hub assembly and works with “Side B” of the Module on
the user’s mounting surface. Codewheel HEDM-6141
Option TXX and HEDM-5041-Bxx has the Artwork Side
opposite the “Hub Side” and works with “Side A” of the
Module on the mounting surface. For the Index to oper-
ate, these parts must be oriented as shown in Figure 7a
and 7b.
