RESR angle encoder system

The RESR is a one-piece System features

High speed, non-contact, stainless steel ring with

optical performancegraduations marked directly

Graduation accuracy to 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.

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

± 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 (Ø52 mm to Ø550 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

RESR angle encoder system

Resolution

The RESR offers a range of standard ring diameters, as well as sizes that offer line counts that provide 2n counts per revolution or resolutions that are precise sub-divisions of degrees or arc seconds.

Note: 1 arc second resolution = 1.296 x 106 counts per revolution = 2.778 x 10-4 degree resolution.

Graduation error is the maximum difference between the angle measured by a single readhead and the true rotation of the encoder as graduated. Application disturbances such as eccentricity are not included.System error is graduation error plus SDE.

Effects such as eccentricity influence installed performance; for application advice please contact your local representative.
