INDUcoder, a British/German company, has plenty of Hollow Shaft Encoders to offer. If you are looking for an optical incremental encoder with hollow shaft or through hollow shaft, then shaft encoder EDH75/ EDH751 would be the perfect choice.

Technical specifications of EDH75 / EDH751 shaft encoder can be found here.

Selection of a smaller shaft encoder is also available, namely the EDH26.

Resolutions of 1 - 2500 pulses per revolution, every number of pulses available
3 or 6 output channels - push-pull outputs or RS422 line driver
Rotational speed of 10.000 rpm
High shaft loading 20 N radial and 10 N axial, high shock resistance 1000 m/s²

The EDH26 is definitely an economic buy for smaller scaled projects. Read more about EDH26 specifications.

Absolute Shaft Encoders from J Darbyshire and Son Limited

Absolute shaft encoders, sometimes named as shaft-angle encoders, are not only used to detect angular positions, but also suitable for linear movements that can be converted into rotary movements by a toothed belt, drive pinion, or wire winch.

The special feature of absolute shaft encoders is that they assign
a unique, digitally encoded signal to each individual measured
increment.

The method of transducing prevents the incorrect readings, even by a power cut, or a momentary malfunction. After the encoder is still connected, or the power is reconstituted, the position is able to provide readings. It is not necessary to move with a position of reference, because it is for encoders center type by incremental.
