Incremental linear encoder VIONiC™ RSLM20

opticaldigital outputIP40

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 RSLM20 scale? RSLM20 is a stainless steel spar scale featuring 20 µm pitch incremental graduations and a variety of IN-TRAC optical reference mark options, including regularly spaced for customer selection or single reference at the centre or the end of the scale. It is comparable to fine pitch glass scales and offers a total accuracy (including slope and linearity) better than ±4 µm over a 5 m length. It can also be coiled for simple storage and handling yet once uncoiled behaves as a spar scale. System designers can choose between specially formulated adhesive tape or mechanical clips to suit mounting requirements. Both mounting methods allow for independent thermal expansion to that of the substrate.
