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.
