Note:
These dimensions include shaft endplay and codewheel warp. All dimension for mounting the module and codewheel
should be measured with respect to two mounting boss, as shown above.

Notes
Recommend to mount the codewheel closer to the detector side
(upper side) for optimum encoder performance.

Note: The customization of codewheel method is valid from theoretical
standpoint. However Avago Technologies strongly recommends a full
characterization to be done to determine the actual performance of
the encoder with customized codewheel.
Characterization means validating the encoding per-
formance (consist of cycle error, pulse width error, logic
state width error, phase error, position error & index pulse
width , index channel rise and fall time) over the recom-
mended operating conditions and recommended mount-
ing tolerances.
