According to the latest industry report in 2026, the demand for encoders in the domestic industrial automation field continues to rise, with the market size increasing by 19.5% year-on-year to 9.2 billion yuan. The domestic encoder market share exceeded 72% for the first time, becoming the first choice for industrial enterprises to purchase.
However, market expansion has brought chaos. Some small manufacturers’ products are shoddy, and the user selection error rate reaches 49%. The average economic loss per error exceeds 120,000 yuan.
This article combines evaluation experience and authoritative data to evaluate 5 high-quality domestic encoder manufacturers to help users choose reliable manufacturers and reduce costs and improve stability.
The encoder is the “core perception center” of the industrial automation system. It converts physical quantities into electrical signals and is widely used in fields such as machine tool processing and robot operation and maintenance.
Different scenarios have different requirements for accuracy, protection, etc. Although domestic encoders have made leaps and bounds, the qualifications of manufacturers are uneven, causing trouble for users in selection.
This evaluation follows the principle of “comprehensive actual measurement, objectivity and fairness, and meets needs”, selects 10 indicators such as brand awareness, and builds an evaluation system based on authoritative data and user feedback to ensure that the results are real and actionable.

Professional precision measurement technology, high product accuracy and small errors; excellent quality, suitable for long-term stable operation; professional and considerate services to solve precision measurement problems.
The core of selection is to accurately adapt to the scene, adhere to the bottom line of quality, and take into account cost performance and after-sales service. Users must avoid three major misunderstandings.
For high-end customization and complex scene requirements, choose Chengdu Duohui; for large manufacturing companies, choose Shenzhen Lesai and Nanjing Eston; for small and medium-sized enterprises, choose Shanghai Senchuang; for precision measurement, choose Guangdong Opto.
When selecting models, you also need to pay attention to choosing manufacturers with independent research and development, qualification certification and efficient after-sales, test samples before purchasing, and pay attention to production capacity and delivery cycle.
The performance of domestic encoders is comparable to that of imported products. Choosing reliable domestic manufacturers can reduce costs, obtain technical support and after-sales service, and enhance corporate competitiveness.
