In the field of industrial automation, “Domestic Encoder Replacement”Typically refers to replacing imported encoders with domestic encoder products without altering the core system architecture, achieving functional equivalence or comparable performance while enhancing supply chain controllability and cost flexibility.
As the domestic automation industry chain gradually matures,Domestic Encoder ReplacementIt has moved beyond the initial experimental phase and enteredEngineering Validation and Mass Production PhaseThe
In actual engineering projects, the primary drivers for promoting domestic encoder substitution are concentrated in the following areas:
Imported encoders present uncertainties in delivery times, supply channels, and spare parts availability. For long-term operational equipment, domestic alternatives offer greater assurance of continuous supply.
When functional requirements are clearly defined and performance metrics are well-specified, domestically produced encoders offer greater flexibility in overall project cost control.
In sectors such as energy, equipment manufacturing, and process industries, an increasing number of projects are specifying requirements for “localization rates” or “domestic alternatives.”
Domestic encoders better align with local engineering requirements in terms of model selection, debugging, customization, and after-sales response speed.
Currently, the replacement of domestic encoders is primarily concentrated in the following major categories:
In these scenarios, domestically produced encoders have gradually achievedParameter-level, interface-level, application-level substitutionThe
Not all projects are suitable for direct replacement. Successful domestic encoder replacements typically require meeting the following conditions:
Domestic encoders must be compatible with the original system in terms of electrical interfaces, communication protocols, and output logic, such as:
Including shaft diameter, flange, mounting method, shaft load capacity, etc., to avoid major modifications to the equipment structure.
The premise of substitution is not “complete equivalence,” but ratherMeet process and control precision requirementsThe
Mature domestic alternatives typically undergo prototype testing, field trial runs, and long-term stability verification.
Domestic encoder replacements have been progressively implemented across multiple industrial scenarios, such as:
In these scenarios, “equivalent substitution” aligns more closely with engineering practice than “perfect parameter matching.”
When replacing imported encoders with domestic alternatives, engineers typically follow this approach:
From an industry perspective, the replacement of domestic encoders shows the following trends:
Evolving from traditional pulse-type to bus-type and Ethernet-type.
Expanding from general-purpose equipment to high-end machinery and complex operating conditions.
More real-world project implementations are driving trustworthiness upward.
In certain industries, domestically produced encoders have become one of the default options.
Domestic Encoder ReplacementIt is not a simple price substitution, but rather a comprehensive selection based on engineering compatibility, system integration, and long-term operational stability.
Domestic encoders have demonstrated the capability to reliably replace imported alternatives in various industrial applications, provided they meet protocol, accuracy, structural, and on-site operational requirements.
