What MultiDimension Technology does

MultiDimension Technology Co., Ltd. (MDT) is a privately-held semiconductor company founded in 2010 and headquartered in Zhangjiagang, Jiangsu Province, China, that designs, manufactures, and sells magnetic sensor integrated circuits based on proprietary Tunneling Magnetoresistance (TMR), Giant Magnetoresistance (GMR), and Anisotropic Magnetoresistance (AMR) technologies combined with CMOS signal processing. The company operates its own automobile-certified fabrication facility capable of producing billions of sensor ICs annually, providing vertically integrated manufacturing control over quality and supply chain.

MDT's product portfolio spans ultra-low-power magnetic switch ICs (e.g., TMR1370 at 50nA for CGM wearables, TMR1228D dual-axis for metering), high-performance magnetic rotary encoder ICs (TMR3111D at 40,000 RPM for robotics), precision angle sensors (3111TMR at 0.05-degree precision for humanoid robots), and high-frequency magnetic field probes (HFM2905, DC to 1.6MHz for electronics R&D). The company serves diverse end markets including medical wearables (continuous glucose monitoring), robotics (humanoid, quadruped, industrial servo systems), smart utility metering, automotive electronics, consumer electronics, and EMI/EMC test and measurement.

MDT generates revenue primarily through direct hardware sales of its magnetic sensor ICs via its official online store and through global distribution partner DigiKey, with volume pricing negotiated through its global sales team. The company maintains international offices in Singapore, Tokyo, and San Jose to support regional customer engagement, and it actively markets through industry trade shows such as Electronica Shanghai and press release distribution targeting engineering audiences. No parent company, venture capital backing, or public listing is disclosed in available source material, suggesting founder-led, privately-financed operations.
