LASER ROTARY ENCODER
Canon's Technology Has Changed the World of Rotary Encoders: 81,000 Pulses with 36mm Diameter

Canon laser rotary encoders use the light-diffraction interference method, with a semiconductor laser as the light-emitter element. The result is an ultra-compact size encoder that combined was impossible with traditional rotary encoders. This product is a compact, high-precision rotary-angle sensor that is certain to play a major role in the development of high-technology products that will lead the market in the 21st century in a wide variety of fields such as robotics, manufacturing machinery, and measuring equipment.
