Renishaw: RESOLUTE™ absolute encoder system with RESA30 rotary (angle) ring RESA30USA255B

RESA is a one-piece stain less steel ring with a single track, true absolute scale marked directly onto the periphery. Read by Renishaw’s revolutionary new absolute fine pitch encoder system,

RESOLUTE it has high tolerance to dirt, scratches and greasy fingerprints that can cause other encoder systems to miscount. The RESA offers impressive accuracy with resolution to 0.00030 arc second, suiting the most demanding precision applications. The low-profile RSA, with large internal diameter, is easy to design into most installations. Equally important, its low mass, low inertia design does not compromise system performance. RESA is available in a wide range of sizes and line counts, providing compatibility with industry standard controllers.
