Renishaw launches ATOM, a non-contact optical linear and rotary incremental encoder system that uniquely combines miniaturisation with leading-edge dirt immunity, signal stability and reliability. The new encoder achieves unmatched performance as a consequence of a design which avoids the many compromises traditionally associated with miniaturised encoders.
The encoder, which is available in sizes as small as 6.8 mm x 12.7 mm x 20.5 mm, is the world's first miniature encoder to use filtering optics with Auto Gain Control (AGC) and Auto Offset Control (AOC). This advanced technology is found in Renishaw's proven TONiC incremental encoder range and provides excellent signal stability and exceptional dirt immunity.
The readhead is available in a range of formats and delivers unrivalled metrology performance, offering class-leading accuracy with low Sub-Divisional Error (SDE), low jitter, high signal stability and long-term reliability. ATOM offers speeds to 20 m/s (29,000 RPM on a 17 mm disc) and resolutions to 1 nm (0.004 arc second on a 108 mm disc) with a range of linear and rotary (angle) scales available in stainless steel and glass. The readhead also includes a set-up LED to allow quick and easy installation and an auto-calibration routine to enable faster optimisation.
