Please note:

The greater the installation depth or the more the drive shaft is located in the hollow shaft of the encoder, the better the performance of the encoder and the fewer electrical and mechanical problems will occur.

As a recommendation please always make for encoders with a blind hollow shaft sure that the maximum drive shaft length is reached.
