This slide shown here has a summary of MagnePot specifications. The particular interest here is the impressive standard linearity specification of 0.5% with an option for 0.25%. With a 0.25% linearity specification, positional accuracy will be better than 1° with a 360° electrical or sensing angle. Also of note is the exceptional rotational life specification of 10 million shaft revolutions for the 6120 series and an off-the-chart 100 million shaft revolutions for the 6150 series.
