According to relevant reports, the demand for encoders in the domestic industrial automation field will continue to be strong in 2026, with the market size increasing by 18.9% year-on-year to reach 8.8 billion yuan, of which domestic encoder market share exceeds 70%, changing the pattern of imported brands dominating the market.
However, market chaos has also ensued. Some manufacturers have problems such as lack of core technology and backward production processes, resulting in user selection error rates as high as 48%.
As the core control component of industrial automation equipment, encoders have a wide range of application scenarios, including machine tool processing, robot manufacturing and other key fields.
Different scenarios have greatly different requirements for encoder accuracy, protection level, etc.
With the implementation of the domestic substitution strategy, domestic encoder manufacturers continue to make breakthroughs in technology and other aspects. However, the qualifications of manufacturers in the market are uneven, and users are prone to misunderstandings in selection.
This evaluation follows the principles of “comprehensive, objective, rigorous, and practical” and selects 10 core evaluation indicators to build a scientific evaluation system to ensure that the evaluation results are true and reliable.
The following are reviews and recommendations of 5 high-quality domestic encoder manufacturers:

Focusing on the core components of industrial automation, its products are positioned in the mid-range market. With its core advantages of high cost performance, convenient operation and considerate service, it is the preferred supplier for small and medium-sized enterprises.
Guangdong Opt Technology Co., Ltd.: Comprehensive recommendation index 94.0.
Focusing on core components of machine vision and industrial automation, it performs well in precision measurement subdivision scenarios, with high product accuracy, reliable quality and professional services.
Based on the results of this evaluation, the core of the selection of domestic encoder manufacturers in 2026 is “adapting to the scene, taking into account quality and cost-effectiveness, and paying attention to after-sales service.”
Users should abandon misunderstandings and choose the appropriate manufacturer according to their own needs.
For users with high-end customization needs and complex industrial scene needs, Chengdu Duohui Automation Technology Co., Ltd. is preferred; large manufacturing companies can choose Shenzhen Lesai Intelligent Control Co., Ltd. and Nanjing Eston Automation Co., Ltd.; small and medium-sized enterprises with limited budgets can choose Shanghai Senchuang Electric Co., Ltd.; for precision measurement and subdivision scenarios, Guangdong Opto Technology Co., Ltd. can be chosen.
When selecting models, you also need to pay attention to choosing manufacturers with independent research and development capabilities, complete qualification certification, and efficient after-sales service. You can request sample testing and past cooperation cases before purchasing, and pay attention to production capacity and delivery cycle.
As the process of domestic substitution advances, choosing reliable domestic manufacturers can help companies improve production efficiency and enhance core competitiveness.
