SAN JOSE, Calif. and ZHANGJIAGANG, Jiangsu, China, April 27, 2015 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT) announced the TMR29xx and TMR27xx series, a new lineup of high-performance Tunneling Magnetoresistance (TMR) linear magnetic field sensors with ultra-high sensitivity exceeding 200mV/V/Oe, along with low power consumption and low noise. They are best suited for high-precision or battery-powered high-end industrial sensor applications including weak magnetic field measurement, current sensing, metal object detection, and non-destructive testing (NDT).

"MDT's new high-performance TMR magnetic sensors set the industry's sensitivity record for all semiconductor-based magnetic sensor technologies, including Hall Effect, AMR (Anisotropic Magnetoresistance) and GMR (Giant Magnetoresistance). This leading-edge technical advancement is only made possible with MDT's patented and unique TMR magnetic sensor design and fabrication know-how. Our TMR29xx series will offer new alternatives for high performance sensors to users of performance-critical applications, with good signal-to-noise, reduced complexity and cost of the analog front-end circuit, lower power consumption, smaller size, and enhanced durability, compared to Hall Effect, AMR, GMR, and GMI (Giant Magnetoimpedance) sensors," said Dr. James G. Deak, Co-Founder and CTO of MultiDimension Technology. "With our comprehensive product and service options, including standard packaged devices, wafers or bare-dice, custom designs, foundry service, and IP licensing, we are fully committed to offer the best suitable products or services for our customers."

The TMR29xx/TMR27xx series are in-plane TMR linear magnetic field sensors with most advanced performance metrics. Along with the existing TMR21xx series (prior MMLPxx series) and TMR25xx series (Z-axis linear magnetic field sensors), MDT offers a wide-ranging product portfolio for a variety of industrial and commercial sensor applications including current sensing, position and speed sensing, security monitoring, vehicle detection, e-compass, NDT, motor and fan control, and etc.
