About ATOM DX readheads

  • ATOM DX is Renishaw’s smallest incremental optical encoder with digital output direct from the readhead.
  • ATOM DX readheads combine Renishaw's market proven filtering optics, dynamic signal control and advanced interpolation technology. This provides low SDE, excellent dirt immunity, and eliminates the need for separate interfaces
  • Integral set-up LED for simple installation and calibration
  • Available in two variants; cabled and top exit, for the most demanding space constrained installations
