At Sensors Converge 2026, MultiDimension Technology, a leading manufacturer of magnetic sensors specialising in Tunnelling Magnetoresistance (TMR) technology, founded in 2010 in Zhangjiagang, Jiangsu Province, China, announced the production supply of its ultra-compact TMR linear sensor series, TMR2531 and TMR2539, developed for high-precision smartphone optical image stabilisation (OIS) applications.
Engineered to meet the accuracy demands of next-generation smartphone cameras, the TMR2531 and TMR2539 enable micron-level displacement measurement in voice coil motor (VCM) modules, allowing VCM driver ICs to precisely correct camera shake in real time during photo and video capture. Both models measure the Z-axis perpendicular magnetic field amplitude via a Wheatstone full-bridge configuration with four high-SNR (signal-to-noise-ratio) TMR elements.
Key features of the TMR2531/TMR2539 series include the following: Micron-level positioning accuracy for OIS, TMR2531: ±1000 Gauss linear range, TMR2539: Extended ±1500 gauss linear range.
The rise of periscope-style telephoto lenses has pushed OIS precision requirements into the micron scale to control prism positioning over extended motion ranges. MDT’s TMR sensor technology delivers superior SNR, broad linear measurement ranges, and robust immunity to magnetic interference, making it a powerful upgrade for advanced camera autofocus (AF) and OIS solutions in flagship smartphones.
The TMR2531 and TMR2539 join MDT’s AF TMR sensor series TMR4101 and TMR301X, forming a complete TMR-based solution suite for micron-precision smartphone AF and OIS. They are designed, fabricated, packaged, and tested in MDT’s vertically integrated TMR sensor fab in Zhangjiagang, Suzhou, China, supporting an annual production capacity of multi-billion units to meet the volume demands of the global consumer electronics market.
At Sensors Converge 2026, MDT is also showcasing the latest gaming controllers and gaming keyboards adopting MDT’s linear and angular TMR sensors, along with the recently announced TMR8105 picoTesla weak magnetic field detector, the HF2905 1.6MHz wide-band TMR current probe, and TMR rotary encoder solutions for humanoid robotics applications.
