With the rapid development of economy, the incremental encoder has made rapid progress in the industry. It is a speed and displacement sensor integrating light, machinery and electricity. It has a variety of rituals and a wide range of applications. It has a broad prospect in the market. The market demand is growing rapidly, and will occupy a larger market in the future.

According to China's 12th Five Year Plan for instruments, 500 billion yuan will be invested during the 12th Five Year Plan period, mainly in the R & D and industrialization of incremental encoders. The plan clearly lists the key products and technologies to be developed in the next five years, including new chip, miniaturized, integrated and highly reliable electronic components to meet the development needs of a new generation of incremental encoders; High quality and key electronic components to meet the supporting needs of China's new transportation equipment manufacturing industry; Incremental encoder supporting energy-saving and environmental protection equipment; Incremental encoder supporting the new generation of communication technology.

China's incremental encoder enterprises urgently need to understand the latest changes in the market, develop relevant incremental encoder products according to the progress of the incremental encoder industry, seize the market, and broaden the space for their industry, so as to facilitate their healthy progress in the future. At present, the progress level of China's incremental encoder needs to be increased. We should strive to implement international standards, so as to make China's incremental encoder industry achieve more rapid and sustainable progress.
