Incremental rotary encoder VIONiC™ REXM20

opticalnon-contactdigital output

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 REXM20 ring? REXM20 is a one-piece stainless steel ring with 20 µm pitch incremental graduations marked directly onto the periphery, featuring the IN-TRAC™ optical reference marks. Its larger cross-section allows for the reduction of all installation errors apart from eccentricity, which is easily corrected using a DSi (Dual Signal Interface) and two readheads. It features total installed accuracy up to ±1 arc second, zero coupling losses, and exceptional repeatability. REXM20 is available in a range of sizes (Ø52 mm to Ø417 mm) and line counts, all of which 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.
