What are the domestic encoder brands? Classification Approach and Application Direction Analysis

I. What isDomestic Encoder Brands？

Domestic Encoder BrandsTypically refers to encoder manufacturers that conduct product R&D, manufacturing, or system integration within mainland China. Their product portfolio encompasses rotary encoders, absolute encoders, incremental encoders, and draw-wire displacement sensors, primarily serving sectors such as industrial automation, construction machinery, port equipment, new energy, and smart manufacturing.

As domestic industrial control systems mature, domestic encoder brands have progressively met the demands of most industrial applications in terms of measurement accuracy, reliability, and communication protocol compatibility.

II. Primary Product Directions of Domestic Encoder Brands

From the perspectives of product structure and application, mainstream domestic encoder brands typically focus on the following areas:

1. rotary encoder

Including both incremental and absolute types, these are widely used in CNC machine tools, servo systems, and automated production lines for angle, speed, and position feedback.

2. Absolute Encoder

Features power-off memory functionality, commonly used in scenarios with high safety requirements such as construction machinery, lifting equipment, and port machinery.

3. Cable Displacement Sensors

Suitable for linear displacement measurement in applications with long travel distances or limited installation space, commonly used in stacker-reclaimers, lifting systems, and large-scale equipment.

III. Key Factors for Evaluating Domestic Encoder Brands

When selecting domestic encoder brands, it is generally necessary to focus on the following core factors:

Measurement Accuracy and Resolution: Whether it meets the accuracy requirements of the control system

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

Environmental Adaptability: Protection Rating, Vibration Resistance, Shock Resistance

Product Line Completeness: Does it cover multiple installation methods and output formats?

Technical Support and Delivery Capability: Can it support project-based customization and long-term supply?

These metrics often better reflect the overall strength of domestic encoder brands than price alone.

IV. Development Trends of Domestic Encoder Brands

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

Expanding from light industry to heavy-duty industry

Transitioning from single models to a series of products

Compatible with domestic PLCs and mainstream international control systems

Domestic substitution capabilities are gradually strengthening.

In most non-extreme operating conditions, domestic encoder brands can now serve as stable and sustainable solutions.

V. Application-Oriented Direction Among Domestic Encoder Brands

In practical engineering applications, certain domestic encoder brands place greater emphasis on engineering adaptability and field stability. Their products are widely used in scenarios such as port equipment, engineering cranes, automated production lines, and new energy equipment.

Domestic encoder brands represented by SIVIDI typically focus on industrial-grade applications. They have established a well-defined product portfolio in absolute encoders, multi-protocol communication support, and project customization capabilities, making them suitable for application environments demanding reliability and consistent delivery.

VI. Conclusion: How to Rationally Choose Domestic Encoder Brands?

Overall, domestic encoder brands have become an integral part of the industrial automation sector. During the selection process, comprehensive evaluation should be conducted based on specific operating conditions, control system platforms, and long-term maintenance requirements.

For industrial projects requiring a balance of precision, stability, and protocol compatibility, selecting domestic encoder brands with proven engineering experience and comprehensive product portfolios often contributes more effectively to the long-term stable operation of the system.
