Renishaw Encoders Designed for Miniature Embedded Motion Control ApplicationsJuly 1, 2012
Renishaw's RoLin non-contact magnetic encoder system is designed for embedded miniature motion control in high-volume applications in a wide range of industry sectors including semiconductor, science/medical, military/aerospace, and industrial automation.
Designed for both linear and rotary incremental position feedback, the system consists of an RLM readhead and either a magnetic scale (MS) or magnetic ring (MR) with a pole length of 2 mm, for axial or radial readings.
According to the company, the RoLin provides state-of-the-art sensing technology with highly repeatable position measurement under wide installation tolerances and temperature ranges of -4 degrees to 185 degrees F (-20 degrees to +85 degrees C). Reference marks are bi-directional and position information is output in incremental quadrature format, with optional periodic reference marks (every pole) or unique reference marks available as well.
The electronics inside RoLin's readhead provide interpolation rates up to 13-bit, as well as fault monitoring. The RoHS-compliant encoder is available in eight resolutions ranging from 0.244m to 125m for linear, and 608 to 753,664 CPR for rotary, with speeds up to 40 meters/sec, depending on resolution. Sub divisional error is 3.5 m.
