Renishaw: ATOM™ incremental encoder system linear scale A-9405-4050
ATOM™ encoder series

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.

ATOM DX™ incremental encoder system with RCDM rotary (angle) disc

RCDM is a one-piece glass disc featuring graduations marked directly onto its face and a single reference mark position and optical alignment band. The optical alignment band can be used to minimise alignment errors and improve installed accuracy.

Two versions are available, with either 20 µm pitch or 40 µm pitch incremental graduations, in a range of sizes (20 µm: Ø30 mm to Ø108 mm, 40 µm: Ø17 mm to Ø108 mm).

The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
