The RESM is a one‑piece stainless steel ring with 20 or 40 µm scale marked directly onto the periphery, featuring the IN‑TRAC ™ auto‑phase optical reference mark. The RESM offers impressive accuracy with resolution to 0.00075 arc second, suiting the most demanding precision applications. Read by Renishaw’s VIONiC™, TONiC™ and QUANTiC™ encoder systems, it has high tolerance to dirt, scratches and greasy fingerprints that can cause other encoder systems to miscount. The low profile RESM, with large internal diameter, is easy to design into most installations. Equally important, its low mass, low inertia design does not compromise system performance. Available in a wide range of sizes and line counts, providing compatibility with industry standard controllers.
