What are encoders
In many manufacturing and production processes, in mobile machines and in the area of renewable energies encoders have become established as reliable instruments. To precisely determine the speed, position, angle or direction of rotation of objects, they convert rotary movements into digital signals. Encoders use wear-free magnetic or photoelectric detection. A pulse disc firmly attached to the shaft or a movable magnet carrier ensures this recognition.
