Based on a TMR sensor mass production platform with an annual output of billions of chips, MultiDimension Technology’s full series of products for camera autofocus and optical image stabilization are now shipping in volume to the smartphone market
Santa Clara, California and Zhangjiagang, ChinaMay 6, 2026 /PRNewswire/ — At the Sensors Converge 2026 exhibition, MultiDimension Technology Co., Ltd. (MDT), a leading professional manufacturer of tunneling magnetoresistance (TMR) magnetic sensors, today announced that the ultra-small TMR linear sensor chips TMR2531 and TMR2539, designed for high-precision optical image stabilization (OIS) in smartphone cameras, are now shipping in volume to the smartphone market.
The TMR2531 and TMR2539 are specifically designed for OIS in smartphone cameras, enabling micron-level displacement detection within voice coil motor (VCM) modules, supporting VCM driver chips in precisely compensating for camera shake to enhance image capture stability. Both sensor chips integrate four high signal-to-noise ratio TMR sensing elements into a single Wheatstone full-bridge structure, enabling measurement of vertical magnetic field strength in the Z direction.
Key features of the TMR2531 and TMR2539 series products:
- Micron-level OIS positioning accuracy
- TMR2531: ±1000 Gauss linear measurement range
- TMR2539: ±1500 Gauss linear measurement range
- Resistance to horizontal magnetic field interference: Effectively shields against ±3000 Gauss horizontal interference magnetic fields, ensuring stable operation in VCM environments with strong magnetic interference
- Wide operating voltage range: 1.0 V ~ 5.5 V
- Ultra-small DFN4L package: 0.8 × 0.5 × 0.25mm, supporting space-constrained VCM designs
Although Hall effect sensors have been widely used in smartphone camera modules, with the increasing prevalence of periscope telephoto lenses in today’s smartphones, the accuracy requirements for OIS systems have significantly risen to the micron level, ensuring precise positioning of prisms over a larger anti-shake travel range. MDT’s TMR sensor technology offers superior signal-to-noise ratio, an extended linear measurement range, and strong resistance to magnetic field interference, providing a robust and powerful technology upgrade solution for high-end smartphone camera autofocus (AF) and OIS.
The TMR2531 and TMR2539 join MDT’s existing TMR sensor chip series for autofocus, including the TMR4101 and TMR301X, forming a complete TMR-based solution that achieves micron-level high-precision positioning for smartphone camera AF and OIS. This product series is designed, manufactured, packaged, and tested at MDT’s vertically integrated TMR sensor production base in Zhangjiagang, Suzhou, China. This production line is independently owned by MDT and has an annual capacity of billions of TMR sensor chips, meeting the volume production supply demands of the global consumer electronics market.
At the Sensors Converge 2026 exhibition, MDT will also showcase product cases featuring its TMR linear and angle sensors in the latest gaming controllers and gaming keyboards, as well as the recently released TMR8105 weak magnetic field detector achieving picoTesla-level resolution, the HF2905 wide-spectrum TMR current probe with 1.6MHz bandwidth, and TMR rotary encoder solutions for humanoid robots.
