The RESR is a one-piece stainless steel ring with graduations marked directly onto the periphery. The RESR offers impressive accuracy with resolution to 0.008 arc second, suiting the most demanding precision applications. Read by Renishaw's filtering optics readheads, including the RGH20, RGH34, RGH35 and RGH40, the system has a high tolerance to dirt, scratches and greasy fingerprints that can cause other encoder systems to miscount. The low profile RESR, with a large internal diameter, is easy to design into most installations. More importantly, its low mass, low inertia design will not compromise system performance. A repeatable reference mark is available to provide a home (datum) position, while Renishaw's RGH40 readhead with filtering optics offers dual limit sensors.	System features • High speed, non-contact, optical performance • Graduation accuracy to ± 0.5 arc second • Angular resolution to 0.008 arc second • System repeatability to 0.008 arc second • Wide range of sizes and line counts provide compatibility with industry standard controllers (052 mm to 0550 mm with line counts from 4,096 to 86,400) • Patented taper mount simplifies integration and minimises installation errors • Filtering optics provide excellent dirt immunity	• UHV compatible • Low magnetic permeability as standard • Compact size for easy integration • Low mass and low inertia • Compatible with RGH20, RGH34, RGH35 or RGH40 readheads to offer industry standard analogue or digital incremental outputs with reference mark option • Integral set-up LED on all Renishaw encoders for quick set-up and instant "health check" at any time • Ultra-low inertia versions also available in 75 mm 100 mm, 150 mm and 200 mm sizes
