TONiC™ RESM20 rotary (angle) ring

Renishaw:
RESM rotary scale.

The RESM is a one‑piece stainless steel ring with 20 or 40 µm scale marked directly onto the periphery, featuring the IN‑TRAC ™ auto‑phase optical reference mark. The RESM offers impressive accuracy with resolution to 0.00075 arc second, suiting the most demanding precision applications. Read by Renishaw’s VIONiC™, TONiC™ and QUANTiC™ encoder systems, it has high tolerance to dirt, scratches and greasy fingerprints that can cause other encoder systems to miscount. The low profile RESM, with large internal diameter, is easy to design into most installations. Equally important, its low mass, low inertia design does not compromise system performance. Available in a wide range of sizes and line counts, providing compatibility with industry standard controllers.


Features

  • Compatible with the VIONiC, TONiC and QUANTiC encoder systems offering industry standard analogue or digital incremental outputs
  • IN-TRAC bi-directional optical reference mark
  • Graduation accuracy to ±0.38 arc second (550 mm ring)
  • Patented taper mount simplifies integration and minimizes installation errors
  • Large internal diameter for ease of integration
  • Available in sizes from Ø52 mm to Ø550 mm with line counts from 4 096 to 86 400
  • Custom sizes also available
  • Low mass and low inertia
  • Ultra-low inertia versions also available
  • REST20 is a RESM20 with two reference marks, for use on dual readhead systems in partial arc applications
