Heidenhain also sells absolute encoders that output SSI.
I've used them before. They are expensive. As I recall $800-$900 for
a rotary one.
If they are wired wrong they can easily be destroyed... An electrician
kept changing the wiring and destroyed two of them before I could
intervene.

Possibly not enough resolution for a rotary table.
Something like the Heidenhain angle encoders might be better, they
turn up on eBay occasionally.

Hi Andy,
My definition of absolute encoder for this exercise is as follows:
Given a rotary table of infinite rotations I want the encoder to count to
359.( depending on resolution) and the next position to be 0.000.
The axis position of 90 degrees is always the same place.
The sign +/- tel

What sort of absolute encoder? What do you want to do with it?

If you can't fix it, you don't own it.
