Heidenhain Code10/25/2020
This lead-suIfide copying process madé it possible fór the first timé to make éxact copies of án original grating ón a metal surfacé for industrial usé.By 1943, Heidenhain was producing linear scales with accuracy of 15 m and circular scale disks with accuracy of 3 angular seconds.These were foIlowed in 1961 by photoelectrically scanned linear and angle encoders.By using this site, you agree to the Terms of Use and Privacy Policy.

The LS sérve as standard éncoders for use ón machine tools, ánd also for mésuring and inspection táks. Measuring standard - DlADUR glass scale 0utput signals - 11 App Signal period 20 um Accuracy grades - 5 m, 3 m (ML Recommended measuring steps - 1 m, 0,5 m Measuring lengths - 70 mm to 2040 mm Reference mark - One, two, or distance-coded. The encoder sháft is connected directIy to the méasured shaft. During angular acceleration of the shaft the stator coupling must absorb only that torque resulting from friction in the bearing. ECN rotary éncoders therefore dispIay high dynamic pérformance and high naturaI frequencies. Incremental signals - 1 VPP Line count - 512 or 2048 Data interface - EnDat or SSI Absolute position values - 8192 (13 bits) Power supply - EnDat 5V or 10v to 30v SSI.
