The rotary encoder in the Chinese mainland are mainly used in machine tools, elevators, electrical package, textile / packaging / printing machinery, lifting machinery and other OEM industries, including elevators, machine tools and motor supporting a key application areas, accounting for 53% market share in the overall market.

Field of textile machinery, packaging machinery and printing machinery and other smaller market share, mainly due to the overall level of automation of these areas have not yet reached the stage of a large number of rotary encoder, rotary encoder applications scattered, and mostly supporting the servo motor, the rotary encoder is generally not directly into these three sectors, the rotary encoder manufacturers, competition is mainly concentrated in the motor servo motor manufacturing plant to machinery industry sectors. Lifting machinery market share is also smaller, only 4-5%, the industry is characterized by the rotary encoder product performance requirements of high non-standard products more particularity, the trade monopoly strong, is still the development and application of primary stage. Project-oriented industries of metallurgy, and electronics industries, the rotary encoder is the amount of application of the ratio is low, only 14% of market share, which is determined by the product application characteristics of the rotary encoder (usually installed in the machinery with the motor using the ), project-oriented industries, direct procurement of the encoder is less than the OEM industry. In addition, the rotary encoder in the field of medical equipment, wind power, automotive production line, hybrid cars, water, rail transportation and other certain applications, is currently in the application development stage, application of a lower proportion.

It is worth mentioning that, in 2009, the wind power industry trend growth, the growth in demand of automation products to more than 50%, while the main fields of application of the elevators, servo motors and machine tools encoder growth is more obvious, so bring the encoder industry to achieve positive growth in the overall market size, growth rate of 5.8%, 15.3% increase in the number, a dash of color in the discrete sensor market.
