The AB output has a hysteresis of 1 bit built in to every move. Sounds like you would have to have computer comensation to resolve the lost bit.

"I rather think it's worth playing with. Get some definitive results.

The main issue is that a pickup head won't read anything when stationery.

You'd have to use hall effect devices."





One of my e-mail newsletters directed me to a site that has a "new" linear magnetic encoder. There I found the datasheet at http://www.austriamicrosystems.com/eng/Products/Magnetic-Encoders/Linear-Encoders/AS5311/AS5311_Datasheet_v1_00 and an evaluation board at http://www.austriamicrosystems.com/eng/content/view/full/15431. I believe the evaluation board was listed as $59.00 on their "buy now" site and the encoders were listed at $6.?? in 1000 pc quantities. It seems like this stuff was designed just for your application although I didn't get a chance to more than glance at the two .pdf files mentioned.
