Non contact magnetic incremental rotary encoder
RENISHAW
For embedded motion control applications, RoLin™ is a component level non-contact magnetic encoder designed for use as a position control loop feedback element. The system consists of a readhead and magnetic scale or ring, with electronics inside the readhead allowing high interpolation rates up to 13 bits and fault monitoring. A wide range of resolutions is available from 0.244 µm to 125 µm, with speeds up to 40 metres/sec dependent on chosen resolution. Radial or axial reading of the ring is possible, and applications are expected to be for high volume, miniature axes in a wide range of industry sectors.
