About the QUANTiC series of super-compact encoders:

  • QUANTiC readheads ensure excellent motion control performance in a wide range of applications
  • A new detector design provides an additional layer of signal filtering which gives superior signal purity and contamination immunity, and ensures low sub-divisional error (SDE)
  • QUANTiC digital encoders include Renishaw’s high-performance integrated interpolation technology, removing the need for additional adaptors or separate interfaces
  • Easy-to-use built-in installation and calibration functions can be enhanced with the optional ADTi-100 Advanced Diagnostic Tool (A-6195-0100), providing real time encoder data feedback during installation or for in-field diagnostics
  • CAD model of the QUANTiC readhead is available from the Renishaw website
