Mounting Considerations
The HEDS-654x/HEDL-654x must be aligned with respect to the optical center (codewheel shaft) as indicated in the
following figure.
If neither locating pins nor locating boss are available, then a centering tool supplied by Avago can be used (HEDS-
6510).
The following figure shows how the main encoder components are organized.
