MDT Reveals Z-Axis TMR Sensors for eCompass and Current Sensors

- MDT's Unique TMR Technology Creates New Z-Axis TMR Sensors as Alternatives to Hall Effect Sensors with Superior Performance and Ultra-Low Power

SAN JOSE, California and ZHANGJIAGANG, Jiangsu, China, Nov. 19, 2013 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, has introduced advanced Z-axis TMR sensors. The new Z-axis TMR sensors are compatible with Hall Effect sensors in the sensing direction as they measure the perpendicular magnetic field penetrating the sensor surface. They offer new options that are well suited for multi-axis eCompass, current sensors, and general-purpose linear magnetic field sensing, with the advantages of TMR sensors including high sensitivity, low noise, ultra-low power, and excellent thermal stability, which Hall Effect sensors cannot provide.

"The invention of MDT's Z-axis TMR sensors is a significant breakthrough in the advancement of magnetic sensor technology. We have overcome the difficult process and design challenges necessary to develop the Z-axis TMR sensors, while maintaining the outstanding features of our present in-plane TMR sensors. Our customers will be able to adopt the Z-axis TMR sensors with the same mechanical structure or magnets designed for present Hall Effect solutions, while enjoying the benefits of TMR technology that are not offered by Hall Effect sensors." said Dr. Song Xue, Chairman and CEO of MultiDimension Technology. "Z-axis TMR sensors can be integrated into multi-axis eCompass, custom designs such as current sensors, or delivered as standalone devices for general-purpose linear magnetic field sensing. We expect that they will bring the benefits of MDT's TMR technology, with better performance, lower power, and enhanced usability to a wider segment of the magnetic field sensing market that is now dominated by Hall Effect sensors."

Unique Features of MDT's Z-Axis TMR Sensors That Are Not Available in Hall Effect Sensors:

• High sensitivity customizable over 1mV/V/Oe
• Resistance easily tunable over a wide range up to several Mega Ohms to match diverse application requirements from high-speed to ultra-low power
• Low noise spectral density and wide bandwidth
• Excellent thermal stability between -40~125 degree Celsius

MDT is the first volume supplier of TMR sensors with multiple product portfolios, including TMR magnetic switches, TMR linear magnetic field sensors, TMR angle sensors, TMR gear tooth sensors, and TMR magnetic pattern recognition sensors. The Z-axis TMR sensors are expected to join MDT's product family in Q1 2014.
