Encoder Discs

Encoder discs work by translating motion into electrical signals to obtain information of speed, position, or direction. Typical applications include process and machine control, motor feedback, factory automation, conveying, robotics, high-accuracy motion control, positioning, and measurement applications.

Accuracy of control depends on the resolution or counter per revolution of an encoder disc, which is determined by the accuracy and consistency achieved. With electroforming, high resolution encoders with high aspect ratio and excellent accuracy can easily be made.

Another advantage of Veco’s Electroforming technology is that reflective encoder discs, on which the light source and the detectors are all located at the same side, can also be developed.  This provides designers the opportunity to build small, single-sided detection systems which is valuable for the continuing demand for miniaturization.
