RESA is a one-piece stain l ess steel ring with a single track, true absolute scale marked di r ect l y onto the periphery.
Read by Renishaw’s revolutionary new absolute fi ne pitch encoder sys t em,
, it has high tol e r a nce to dirt,
scratch e s and greasy fi n g erprints that can cause other en c od e r sys t ems to mis c ount.The RESA offers impressive accuracy with resolution to 0.00030 arc second, suiting the most demanding precision applications. The low profi le RESA, with large internal di a m e t er, is easy to design into most in s tal l a t ions. Equally important, its low mass, low inertia design does not compromise system per f or m ance. RESA is available in a wide range of sizes and line counts, providing compatibility with industry standard controllers.
