• Manufacturer Part Number: HEDS-5120-A01
• Description: Two and Three Channel Codewheels for Use with Agilent Optical Encoder Modules
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Mounting Rotary
Encoders with
Codewheels
There are two orientations for
mounting the Agilent encoder
module and Agilent codewheel.
Figure 1a shows mounting the
module with side A as the
mounting plane. Figure 1b shows
Figure 1a.
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.
IMAGE SIDE
OF CODEWHEEL
*Please note that the image side of the codewheel must always be facing the module Side A.
mounting the module with side B
as the mounting 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.
Mounting with Module
Side B as the Mounting
Plane, using Agilent
Assembly Tools
Agilent 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.
