Description

What is VIONiC? The VIONiC readhead combines Renishaw's market proven filtering optics and advanced interpolation into one digital incremental encoder with ultra-high accuracy. The VIONiC encoder system offers a wide variety of speed and resolution configurations, and an expansive range of linear or rotary scale options. This makes it one of the most versatile encoder for high precision feedback. Designed with intuitive auto-calibration mode, VIONiC readheads are also easy to install. What is new? *The VIONiC encoder system is now available in resolutions down to 2.5 nm with enhanced SDE across the product range. What is RESM20 ring? RESM20 is a one-piece stainless steel ring with 20 µm pitch incremental graduations marked directly on the periphery, featuring the IN-TRAC™ optical reference marks. Two versions are available in a wide range of sizes (Ø52 mm to Ø550 mm): ‘A' section rings, which offer an impressive installed accuracy and feature a taper mount system which reduces the need for highly toleranced machined parts and eliminates eccentricity; ‘B' section thin rings, which have low inertia and mass, are also available. Both 'A' and 'B' section rings have a large internal diameter for flexible integration. The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
