SSI Absolute Encoder: The Core Component for High-Precision Digital Position Measurement and Control

In industrial automation, construction machinery, robotics, and precision equipment,SSI Absolute EncoderIt is a critical rotary or linear position measurement and control sensor. By outputting absolute position data via **SSI (Synchronous Serial Interface)**, it delivers high-precision, reliable, real-time angular and displacement feedback, providing core support for servo control, multi-axis coordination, and automation systems.

I. Overview of SSI Absolute Encoder

SSI absolute encoders convert mechanical position into digital signals using optical, magnetic, or inductive principles, and transmit them via a synchronous serial interface. Their key features include:

• Absolute Position OutputAfter power loss, the current position can be obtained without requiring a reset.
• High-precision measurementResolution can reach thousands to tens of thousands of counts, meeting high-precision control requirements.
• Digital Signal TransmissionStrong anti-interference capability, stable and reliable data
• Multiple axis types availableSolid shafts, hollow shafts, multiple mounting flanges
• Wide range of applicationsIndustrial automation, robotics, multi-axis machinery, and precision instruments

The digital output of the SSI interface ensures stable signal transmission over long distances, during high-speed motion, or in environments with electromagnetic interference, thereby maintaining system measurement and control accuracy.
