Renishaw: ATOM scales ( RCDM)
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.
