Renishaw Miniature incremental optical encoder

The Atom noncontact optical linear and rotary incremental encoder system combines miniaturization with dirt immunity and signal stability. With a readhead as small as 6.7 x 12.7 x 20.5 mm, the encoder uses filtering optics with auto-gain control and auto-offset control. The system offers low sub-divisional error and low jitter as well as analog speeds to 20 m/s (29,000 rpm on a 17-mm disc) and digital resolutions to 1 Nm when used with the company’s interpolation electronics. The readhead includes a set-up LED and an auto-calibration routine. Scale options include linear and rotary (angle) scales in stainless steel and glass.
