The mechanical interface consists in all those components that allow the coupling of the encoder to the machine or device of application, which are:

1. An axle, connected to the shaft of the machine in rotation, designed in accordance to the type of fixing:
   solid shaft, blind and through hollow shaft;
2. A flange, which fixes and adjusts the encoder to its support;
3. A case (or body), which contains and protects the disc and the electronic components.

Elastic couplings can also be employed to adapt the fixing between the motor shaft and the encoder.
