Which domestic manufacturers produce absolute encoders? An analysis of technical capabilities and application dimensions

In the fields of industrial automation, construction machinery, and new energy equipment, absolute encoders are widely used in critical control systems due to their features such as power-off position memory and high positioning reliability. With the continuous advancement of domestic production,“Domestic Absolute EncoderManufacturers have become the primary focus of equipment manufacturers and system integrators.

So, how should we understandDomestic Absolute EncoderManufacturer? How should one evaluate its technical capabilities?

I. What is an absolute encoder manufacturer?

An absolute encoder manufacturer refers to an enterprise capable of independently developing and producing absolute encoder products. These products output unique and definitive position data regardless of whether they are powered on or off.

Compared to incremental encoders, absolute encoders offer manufacturers:

Encoding Algorithm

Signal Stability

Interference resistance

Engineering Validation Experience

This places higher demands on manufacturers, thereby better reflecting their technical depth.

II. Current Development Status of Domestic Absolute Encoder Manufacturers

In recent years, domestic absolute encoder manufacturers have made significant progress in the following areas:

Multi-turn absolute value encoding technology is gradually maturing.

Industrial protocol support capabilities have been significantly enhanced.

Forming practical applications in fields such as construction machinery and new energy

Enhanced Adaptability of Domestic Control Systems

Domestic manufacturers have gradually transitioned from the early stage of “functional viability” to “engineering reliability.”

III. Primary Product Types of Domestic Absolute Encoder Manufacturers

1. Singleturn absolute encoders

Suitable for equipment with clearly defined angular ranges and relatively simple structures, such as rotary platforms and valve actuators.

2. Multi-turn absolute encoders

Widely used in scenarios requiring multi-turn position recording, such as construction machinery, lifting systems, and wind power equipment.

3. Rotary Absolute Encoder

Used for angle, direction, and position feedback, it is a core sensing component in industrial automation systems.

4. Linear/Draw-Wire Absolute Encoder

Used for linear displacement measurement, commonly found in telescopic mechanisms and stroke control systems.

IV. Key Evaluation Criteria for Domestic Absolute Encoder Manufacturers

1. Protocol and Interface Support Capabilities

Mature domestic absolute encoder manufacturers typically support multiple industrial communication protocols, such as:

SSI, CANopen, Profinet, Profibus, RS485, 4–20mA, Parallel IO

Multi-protocol support means greater system compatibility.

2. Engineering Applications and Industry Coverage

Whether stable applications have been established in the following fields serves as a key indicator of a manufacturer's capabilities:

construction machinery

Automated production line

Port and Lifting Equipment

New Energy (Wind Power, Photovoltaic)

Metallurgical and Mining Equipment

3. Domestic Substitution and Customization Capabilities

During the replacement process of absolute encoders, the following aspects are often involved:

Installation dimensions match one-to-one

Electrical Interface and Signal Logic Adjustment

Environmental Rating Adaptation (Vibration, Temperature, Protection)

Manufacturers with customization capabilities are better suited for complex project requirements.

V. Industry Practice Examples of Domestic Absolute Encoder Manufacturers

From an industry application perspective, some domestic absolute encoder manufacturers have gained practical validation in mid-to-high-end equipment. For example,SIVIDIIn the field of absolute rotary encoders and draw-wire absolute encoders, we have established a product portfolio covering multiple protocols and mounting configurations. We have also participated in domestic substitution applications within construction machinery and automation projects.

Domestic manufacturers that grow through project-oriented development are better positioned to demonstrate their technological stability in real-world applications.

VI. Comparison Between Domestic Absolute Encoder Manufacturers and Imported Brands

Dimension	Domestic Absolute Encoder Manufacturers	Imported Brands
Cost	More cost-effective	Higher costs
Delivery time	Stable and controllable	Vulnerable to supply chain disruptions
Customization Capabilities	flexible	Longer cycle
Local Technical Support	Quick response	heavily reliant on agents
Adaptation for domestic systems	more user-friendly	Additional debugging is required.

In most industrial applications, domestically produced absolute encoders have already demonstrated strong replacement capabilities.

VII. Conclusion

“Domestic absolute encoder manufacturers” is not merely a brand concept, but ratherA comprehensive demonstration of technical capabilities, engineering expertise, and service systemsThe
During the selection process, it is recommended to focus on:

• Protocol and System Compatibility
• Actual Engineering Application Cases
• Customization and Domestic Substitution Experience
• Long-term supply and technical support capabilities

With the continuous accumulation of domestic technology, domestically produced absolute encoders are gradually becoming a reliable choice.
