37D Metal Gearmotor Encoder Shaft Dimension

Hello. Can you provide me the dimensions of the rear shaft that the magnetic encoder is attached to? Specifically, I would like to know the how far out the shaft extends from the motor body and the diameter of the shaft.

Thanks in advance.


I moved your post to the motor controllers/drivers and motors support category since it is more appropriate here.

Measured from where the metal motor body meets the base of the plastic case, the back shaft extends around 11.5 mm (though there can be some axial play). The diameter of the back shaft is 2mm.

By the way, I am not sure what you need these dimensions for, but please keep in mind we do not expect the back shaft of these motors to be practical to use. The magnetic disc for the encoder is press fit onto the shaft making it difficult to remove without damaging the disc and the shaft.
