My controls engineer may have to clarify, but I don't recall any dead band. They simply rollover at the zero point.
They do have a deadband at the rollover point, the rollover isn't a perfect "sawtooth". We've used Vishay 357s which after the rollover remain zero for 10-20 degrees. These appear to have similar specs.

If you can live with the deadband, we very much like them. Continuous pots have been much more robust then any encoder we've used.
