Technical Data
HEDS-51X0/61X0 Series
HEDG-512X/612X Series
HEDM-512X/61XX Series
Features:
• Codewheels Available in
Glass, Film, and Metal
• Available in Two Standard
Diameters
• Cost Effective
• Resolutions from 96 CPR to
2048 CPR
• For Use with HEDS-90XX/
91XX Series Two and Three
Channel Encoders
Each of the three codewheel
materials offers a certain
advantage. Metal codewheels are
the most versatile, with a tem-
perature rating up to 100°C,
resolution to 512 CPR (28 mm
diameter), as well as 2 and 3
channel outputs. Film codewheels
offer higher resolution (up to
1024 CPR on a 28 mm diameter)
with an operating temperature of
70°C. Glass codewheels combine
the best of film and metal, offer-
ing a temperature rating of 100°C
and resolutions to 1024 CPR on a
28 mm diameter.

Description
Hewlett-Packard offers a wide
variety of codewheels for use
with Hewlett-Packard’s HEDS-
9000, HEDS-9100, HEDS-9040,
and HEDS-9140 series Encoder
Modules. Designed for many
environments, applications, and
budgets, HP codewheels are
available in Glass, Film, and
Metal. These codewheels are
available in resolutions from 96
Counts Per Revolution (CPR) to
1024 CPR on an 11 mm optical
radius and 500 to 2048 CPR on a
23.36 mm optical radius.
In addition, each material offers a
specific reliability rating. It is
important to consider the specific
application operating environ-
ment, long term operating
conditions, and temperature
ranges when choosing a code-
wheel material.

Absolute Maximum
Ratings
It is important to consider the
environment in which the
codewheels will be used when
selecting a codewheel material. In
brief, metal codewheels are
rugged, but do not offer higher
resolution capabilities. Film
codewheels allow higher
resolution, but cannot endure the
same temperatures and high
humidity as metal. Glass
codewheels offer both high
temperature and higher
resolution, but are also more
expensive. Consider the following
rating table when choosing a
codewheel material.

consistent, large temperature
swings over the life of the product
will affect the codewheel
depending on the material. The

Mounting Rotary
Encoders with
Codewheels
There are two orientations for
mounting the HP encoder module
and HP codewheel. Figure 1a
shows mounting the module with
side A as the mounting plane.
Figure 1b shows mounting the
module with side B as the mount-
ing plane. When assembling the
encoder and codewheel, it is
important to maintain the
tolerances of Side A of the
module, and the image side of the
codewheel. See module Data
Sheets for these tolerances.

Figure 1a.
*Please note that the image side of the codewheel must always be facing the module Side A.
Mounting with Module
Side B as the Mounting
Plane, using HP Assembly
Tools
Hewlett-Packard offers centering
tools and gap setting tools only
for the case when the module is
mounted with Side B down.
Please refer to the Ordering
Information Table to choose the
correct assembly tools.
Mounting with Module
Side A as the Mounting
Plane
Mounting a high resolution or
three channel encoder with
Module Side A as the mounting
plane requires alignment pins in
the motor base. These alignment
pins provide the necessary
centering of the module with
respect to the center of the motor
shaft. In addition to centering, the
codewheel gap is also important.
Please refer to the respective
encoder data sheet for necessary
mounting information.

Assembly Instructions
Using HP Assembly Tools
Instructions
1. Place codewheel on shaft.
2. Set codewheel height:
4. Slide the HEDS-8905 or HEDS-
8906 centering tool over
codewheel hub and onto
module as shown in Figure 3.
The pins of the alignment tool
should fit snugly inside the
alignment recesses of the
module.
shim should not contact the
codewheel boss.
(b) Push codewheel down
against gap setting shim. The
codewheel is now at the proper
height.
(a) Place the correct gap
setting tool (per Ordering
Information Table) on motor
base, flush up against the
motor shaft as shown in Figure
2. The shim has two different
size steps. Choose the one that
most closely matches the width
of the codewheel boss. The
(c) Tighten codewheel
setscrew.
5. While holding alignment tool in
place, tighten screws down to
secure module.
3. Insert mounting screws
through module and thread
into the motor base. Do not
tighten screws.
6. Remove alignment tools.
