Here you’ll find answers to the most common questions about Absolute Magnetics Technology:
An absolute magnetic encoder is a sensor that measures angular or linear position using magnetic fields. Unlike incremental encoders, it assigns a unique digital code to each position, allowing it to retain accurate position data even after power loss. This makes it ideal for robotics, automation, and motor control systems requiring reliable, repeatable performance.
An absolute magnetic encoder works by detecting the orientation of a magnet relative to a sensing chip. The sensor measures magnetic field components and converts them into digital angle or position data. This data is transmitted through interfaces such as SSI, BiSS, or CANopen, ensuring precise, absolute feedback to your control system — even after shutdowns.
Absolute Magnetics AG has developed a multi-periodic magnetization technology that integrates several magnetic tracks into a single measurement pattern. This patented approach delivers accuracy, excellent tolerance to misalignment, and resistance to stray magnetic fields — all without needing complex calibration. The result is a compact, robust, and cost-efficient encoder suitable for demanding industrial applications.
Absolute Magnetics AG encoders deliver accuracy better than 0.5° in standard configurations and can achieve below 0.1° with calibration. Resolutions up to 16 or more bits per revolution are available, depending on the model. This combination of accuracy and robustness makes them ideal for high-precision motion control and industrial automation.
