ATOM DX is Renishaw’s smallest incremental optical encoder with digital output direct from the readhead.

A4A0H15A20F is a miniature incremental encoder readhead, compatible with RTLF40-S, RTLF40H-S, RKLF40-S and RKLF40H-S encoder tape scales. RKLF40 scale is suitable for both partial arc and linear applications and is used in substrate mastered applications where the scale adopts the thermal expansion behaviour of the substrate for enhanced stability.

Cabled A4A0H15A20F features an integral 1.5 m hi-flex cable with a D-type connector, providing positional feedback, onboard interpolation, and filtering optics all in a miniature package.

About the ATOM DX series of miniature digital encoders:

  • Miniature, all-in-one, digital output optical encoder with resolutions down to 2.5 nm

  • 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

  • An optional Advanced Diagnostic Tool ADTi-100 (A-6195-0100) is available for real‑time encoder data feedback during installation or for in-field diagnostics

  • Available in two variants; cabled and top exit, for the most demanding space constrained installations

  • A CAD model of the ATOM DX readhead is available from the Renishaw website 

 

Compatible scales:

RTLF40-S, RTLF40H-S, RKLF40-S or RKLF40H-S (all self-adhesive mounting)
