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

IMAGE SIDE
OF CODEWHEEL
*Please note that the image side of the codewheel must always be facing the module Side A.

MODULE SIDE A
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.
Mounting with Module Side B as the Mounting Plane,
using Avago Technologies Assembly Tools
Avago Technologies offers centering tools and gap set-
ting tools only for the case when the module is mount-
ed with Side B down. Please refer to the Ordering Infor-
mation Table to choose the correct assembly tools.
