Mounting Rotary Encoders with
Codewheels
There are two orientations for
mounting the Avago encoder
module and Avago codewheel.
Figure 1a shows mounting the
module with side A as the
mounting plane. Figure 1b shows
mounting the module with side B
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.

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 Avago
Assembly Tools
Avago 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.
