Description

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 is supplied in hi-flex cable and Flexible-Printed Circuit (FPC) variants with either 20 µm or 40 µm scale options. A range of interfaces is available including the standard Ri, a high-performance Ti and the compact open ACi interface. What is RCDM disc? RCDM is a one-piece glass disc featuring graduations marked directly onto its face and a single reference mark position and optical alignment ring. The optical alignment ring can be used to minimise angular alignment errors and improve installed accuracy. Two versions are available, either 20 µm pitch or 40 µm pitch, 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.
