The Atom noncontact optical linear and rotary incremental encoder system combines miniaturization with dirt immunity and signal stability

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.
