ATOM™ encoder series

What is ATOM?

ATOM is Renishaw's miniature non-contact optical incremental linear and rotary encoder system. Its innovative design combines miniaturisation with leading-edge signal stability, dirt immunity and reliability. This combination is unique in the market place and represents a significant advance in the performance and reliability of miniature encoders.

ATOM systems are simple to install with integrated LED for signal integrity indication.

A range of interfaces is available including high-performance Ti, Ri and the compact PCB ACi interface.

Scale options

  • Linear scales are used where straight-line position information is needed - usually X, Y or Z axes.
  • Rotary scales are used for angular position information and the motion control of rotating elements.
