Shafted: Uses a coupling method to connect the incremental motor encoder shaft to the motor shaft. The coupling provides mechanical and electrical isolation from the motor shaft but can add cost via the coupling and the longer shaft length required to mount the motor encoder.

Hub/Hollow shaft: Direct mount to the motor shaft via a spring loaded tether. This method is easy to install and required no shaft alignment, but proper care must be taken to provide electrical isolation;

Bearningless: Also known as Ring mount, this mounting option is comprised of a sensor assembly in the form of a ring that is mounted on the motor face, and a magnetic wheel which is mounted on the motor shaft. This type of incremental motor encoder mounting configuration is mostly found in heavy duty applications like paper, steel and cranes.
