High-Performance TMR Magnetic Encoder Chip TMR3111D

Supporting both on-axis and off-axis magnetic circuit designs, the TMR3111D delivers a compact magnetic encoder solution for humanoid robots, quadruped robots, servo motor systems, and high-precision motion control. According to MEMS Consulting, MultiDimension Technology, a global leader in magnetic sensors and a pioneer in tunnel magnetoresistance (TMR) technology, recently launched the high-performance TMR3111D magnetic encoder chip. This product provides high-speed, high-accuracy rotational position detection solutions for robotics, servo drives, and industrial motion control. MultiDimension Technology will showcase this product alongside its latest TMR and AMR magnetic sensor series at the 2026 Munich Shanghai Electronica exhibition.

The TMR3111D integrates MultiDimension Technology’s high-sensitivity TMR magnetic sensing technology with advanced digital signal processing to achieve high-speed, high-precision, non-contact rotational position detection within an ultra-compact package. The chip supports both on-axis and off-axis magnetic circuit configurations, offering system designers greater mechanical flexibility while maintaining excellent angular accuracy, repeatability, and long-term stability.

Compared to traditional Hall-effect encoder solutions, MultiDimension Technology’s TMR technology delivers higher magnetic sensitivity, a superior signal-to-noise ratio, and greater tolerance to magnetic field variations and mechanical installation errors. This enables more stable and precise position detection in complex motion control environments, simplifies system integration, and further enhances the overall performance and reliability of next-generation motion control systems. The TMR3111D supports multiple industrial-standard output interfaces, including SPI, ABZ, PWM, and UVW, simultaneously meeting the requirements for both absolute and incremental encoder applications. The chip features built-in automatic gain compensation and non-linearity calibration, which automatically compensates for magnetic field errors caused by installation, improves production consistency, and streamlines assembly processes. Supporting rotational speeds of up to 40,000 rpm, the device is particularly well-suited for high-dynamic motion control applications such as high-speed servo systems and robotic joint actuators.

The TMR3111D is specifically optimized for joint position detection in humanoid and quadruped robots, servo motor systems, collaborative robots, industrial robot joints, precision motion control systems, and other applications requiring high-speed, high-accuracy rotational position feedback.
