What are the domestic encoder manufacturers? Selection Approach and Analysis of Mainstream Directions

I. What isDomestic Encoder Manufacturers？

Domestic Encoder ManufacturersTypically refers to encoder manufacturers that complete product R&D, manufacturing, or system integration within China. Their product portfolio includes rotary encoders, absolute encoders, incremental encoders, and draw-wire displacement sensors, among other types. These products are widely applied in industrial automation, construction machinery, port equipment, new energy, and smart manufacturing sectors.

With the maturation of domestic industrial control systems, domestic encoder manufacturers have gradually approached or even met the requirements of most industrial applications in terms of accuracy, stability, and communication protocol compatibility.

II. Primary Product Types of Domestic Encoder Manufacturers

From a technical and application perspective, mainstream domestic encoder manufacturers typically possess the following product capabilities:

1. rotary encoder

Includes both incremental and absolute types, primarily used for angle, velocity, and position feedback. Commonly found in CNC machine tools, automated production lines, and servo systems.

2. Absolute Encoder

Features power-off memory functionality, suitable for applications demanding high safety and reliability standards such as construction machinery, lifting equipment, and port machinery.

3. Cable-pull Displacement Sensor (Cable-pull Encoder)

For linear displacement measurement, suitable for applications with long travel or limited installation space, such as stacker-reclaimers and lifting systems.

III. Key Technical Indicators for Evaluating Domestic Encoder Manufacturers

When selecting domestic encoder manufacturers, it is generally necessary to focus on the following key aspects:

Measurement Accuracy and Resolution: Whether it meets system control requirements

Industrial protocol support capabilities: such as Profinet, Profibus, CANopen, SSI, RS485, 4–20mA, parallel I/O, etc.

Environmental Adaptability: Protection Rating (IP65 / IP67), Vibration Resistance, Shock Resistance

Customization and Delivery Capabilities: Support for non-standard parameters and project-based customization

Long-term supply and technical support: Meeting the ongoing needs of domestic substitution projects

These factors often better reflect the overall capabilities of a domestic encoder manufacturer than price alone.

IV. Development Trends of Domestic Encoder Manufacturers

In recent years, domestic encoder manufacturers have collectively exhibited the following trends:

Protocol localization and international compatibility in parallel: Simultaneously compatible with domestic PLCs and mainstream international control systems.

Application Scenarios Expand: From Light Industry to Heavy-Duty Equipment and Complex Operating Conditions

Customization Ratio Increase: Project-based orders and industry-specific models on the rise

Enhanced Import Substitution Capability: Achieving stable operation under non-extreme conditions

V. Technical Direction Among Domestic Encoder Manufacturers

In certain industrial applications, some domestic encoder manufacturers have developed product systems focused on engineering applications. For instance, in heavy-duty machinery, port equipment, and automated production lines, they emphasize enhancing absolute measurement accuracy, multi-protocol communication capabilities, and structural reliability.

Domestic encoder manufacturers represented by SIVIDI typically focus on industrial-grade applications. Their encoder products are progressively meeting the demands of domestic substitution and export-oriented projects in terms of protocol compatibility, structural stability, and project delivery flexibility.

VI. Conclusion: How to Select the Right Domestic Encoder Manufacturer?

Overall, when selecting domestic encoder manufacturers, evaluations should be based on specific application conditions, control systems, precision requirements, and long-term maintenance needs. As domestic technological capabilities advance, an increasing number of domestic encoder manufacturers are becoming viable options for industrial projects.

For application scenarios requiring a balance of stability, protocol compatibility, and customization capabilities, selecting domestic encoder manufacturers with proven engineering expertise and consistent supply capabilities often delivers greater long-term value.
