Linear/rotatory encoder

Ran across demo recently of magnetically encoded strips that can be stuck to flat surface and red by sensor with resolution down to 0.01mm. Product mfg'r is Siko...found at www.siko.de. According to the sales rep. one can purchase mag. tape and sensors without all of the other trimmings (readouts, etc.). Strips are available in lengths up to 90 meters and can be cut to desired length. Strips can be stuck to curved surface for rotatory readout. Also they have an absolute position sensing strip so that if power is turned off and then back on the absolute position is still known from the strip. This post is for general interest....rfs/wa8fsf.
