Recommended Domestic Encoders: Selecting Systems Based on Application Scenarios and Technical Specifications

With the advancement of domestic automation equipment and intelligent machinery, the application of domestically produced encoders has gradually expanded across numerous sectors including construction machinery, automated production lines, and new energy equipment. Compared to focusing solely on brand,“Recommended Domestic Encoder”It is even more important to start fromApplication Scenarios, Technical Specifications, and System Compatibilityto determine.

This article will systematically outline for you, based on practical engineering requirements.Recommended Domestic EncodersThe logic and selection criteria.

I. Why Choose Domestic Encoders?

For a long time, the encoder market was dominated by imported brands. However, as domestic control systems and industrial field complexity continue to advance, domestically produced encoders now offer the following advantages:

✅ Supply chain controllability and stable delivery times
✅ Localized technical support with rapid response
✅ Domestic control systems offer superior adaptability.
✅ offers relatively better value for money
✅ The domestic substitution rate continues to increase in engineering projects.

Therefore, when a user asks, “Recommended Domestic Encoders”The core is not merelyWhich brand is good?, and should pay more attention toWhich model/solution is best suited for the current application scenario?The

II. Recommendation Logic for Domestic Encoders (Technology-Oriented)

Before recommending encoders, first clarify the following key selection criteria:

Encoder Type

Different applications have fundamentally different requirements for encoder types:

Type	Typical Applications
Incremental encoder	General speed feedback, relative positioning
Absolute Encoder	Power-off memory, precise positioning
Draw-Wire Displacement Encoder	Long stroke, linear displacement feedback
Ethernet / SSI / RS485 Encoder	Industrial Buses and Networked Control

Communication Protocol Support

When recommending domestic encoders, pay special attention to protocol compatibility, such as:

• SSI
• RS485
• CANopen
• Profinet
• Profibus
• Ethernet (EtherCAT / Profinet / EtherNet/IP)
• 4–20mA / Parallel IO

The degree of protocol compatibility determines the ease and stability of integrating the encoder with the host system.

Environmental Adaptability

Select different structural grades based on site conditions:

• Waterproof and dustproof (IP65/IP67/IP68)
• Vibration-resistant and shock-resistant
• High and Low Temperature Adaptation
• Explosion-proof rating (e.g., Ex d / Ex i / dust explosion-proof, etc.)
