Photoelectric encoder is a new product of the development of modern science and technology, which belongs to the sensor with strong precision, often used in aerospace, industrial control and automatic detection and other fields. Especially with the development of intelligent industry in our country more and more fast, industrial automation system has been widely used, and photoelectric encoder is a very important part, market demand is gradually increasing, followed by the industrial requirements of photoelectric encoder accuracy and efficiency, in order to meet the demand of increasingly diversified industrial manufacturing, photoelectric encoder application technology is constantly optimization and innovation. In this paper, the research focuses on the level of incremental and absolute encoder, on the basis of its application principle and signal output, the paper further clarifies the advantages and characteristics of incremental encoder and absolute encoder, and analyzes the application trend of photoelectric encoder in industrial automation system.
