US Digital began in 1980 in Los Alamitos, California, when founder David Madore could not find an encoder that would meet his design criteria. As a design engineer for a medical ultrasound company, he became aware of the obvious need for optical encoders that were practical, simple, reliable, and available off-the-shelf. US Digital created its first incremental encoder and revolutionized the motion control industry with its user-friendliness and pricing. Today's US Digital products are based on these founding principles.Our mission is to make our customers successful by inventing, manufacturing, and quickly delivering the most practical motion control components worldwide.
