MDT Launches TMR2105 Magnetic Field Sensor

MultiDimension Technology (MDT) introduced a new Tunneling Magnetoresistance (TMR) sensor TMR2105 at Sensors Midwest 2017. The TMR2105 is a general-purpose linear magnetic field sensor with a large dynamic range at 1000 Oe and an ultra-compact 2x1.5 mm LGA package. It is built for a wide diversity of applications, including proximity switches, linear and rotary position measurement, and current sensors.

“MDT’s TMR2105 overcomes a key limitation of Magnetoresistance devices including AMR (Anisotropic Magnetoresistance), GMR (Giant Magnetoresistance) and TMR sensors by extending the operating dynamic range to 1000 Oe. This important breakthrough makes TMR sensors suitable for applications that had favored Hall Effect sensors due to strong magnetic field exposure. With MDT’s patented TMR technology, we have achieved the industry’s best records on highest sensitivity, lowest noise, lowest active-mode power consumption, and largest dynamic range. Our unique expertise can realize a comprehensive range of design options, therefore being competent in satisfying the most demanding requirements by delivering the most suitable products to our customers,” said Dr. Song Xue, founder and CEO of MultiDimension Technology.

MDT is one of the top suppliers of TMR sensors with modern manufacturing facilities and a robust IP portfolio. MDT’s TMR sensors feature a number of exceptional performance benefits, including ultra-low power, ultra-low noise, ultra-high sensitivity, large dynamic range and excellent thermal stability, which compliment limitations of current magnetic sensor technologies including AMR, Hall Effect and GMR. They are suitable choices for a number of consumer, industrial and medical sensor applications.

Features of MDT’s TMR Sensors

  • TMR switch sensors: 1 microampere ultra-low power in high-speed, industry’s maximum switching sensitivity (TMR1309), suitable for battery-powered flow meters and portable devices;
  • TMR magnetic image sensors: High-sensitivity 1/2/3/6/9/12/18-channel magnetic banknote readers for financial anti-counterfeit applications
  • TMR linear sensors: from the industry’s maximum sensitivity and picoTesla noise (TMR9001) to 1000 Oe dynamic range (TMR2105), for current sensing, non-destructive testing (NDT), magnetic field measurement and medical applications;
  • TMR angle sensors: 360° measurement with high-amplitude output in 1000 Oe operating range, for rotary position sensing;
  • TMR gear tooth sensors: Small pitch detection with multiple pitch configurations, for linear or rotary position/speed sensing
