The RoLinTM component level encoder system consists of an RLM readhead and a magnetised ring. The actuator is a periodically magnetised ring with a pole length of 2 mm. Radial or axial reading of the ring is possible. The readhead can ride at up to 0.4 mm from the ring's surface.
State of the art position sensing assures highly repeatable position measurement under wide installation tolerances and temperature range.
The electronics inside the readhead enable high interpolation rates up to 13 bits and fault monitoring. The incremental outputs are re-timed to the chosen minimal edge separation time (from 0.12 µs). The position information is output in incremental quadrature format with the option of a unique or periodic reference mark (every pole).
A wide range of resolutions to 753,664 cpr is available.The maximum speed depends on the chosen resolution and minimum edge separation time, to 4 m/s at 1 µm and to 40 m/s at 10 µm.
