External rotary encoders Internal rotary encoders

External rotary encoders

External rotary encoders excel at measuring rotational motion, angular velocity, and even linear motion when combined with mechanical elements. Areas of application include electric motors, machine tools, printing machines, textile machines, robots, handling equipment, measuring devices, and inspection equipment. The high signal quality of their scanning signals enables nearly perfect speed and motion control within the control loop.
