MDT Announces Three-Axis High-Performance TMR Linear Magnetic Field Sensors


TMR Sensor Technology Achieves 3D Magnetic Field Measurement with Ultra-low Noise, Ultra-high Sensitivity in a C ompact Form Factor for High-precision Industrial or Biomedical Sensor Applications

multi_dimension_logoMultiDimension Technology (MDT) announced TMR23xx series, a new lineup of three-axis high-performance Tunneling Magnetoresistance (TMR) linear magnetic field sensors. They are designed for a variety of application requirements, ranging from large dynamic range at +/-500 Oe, to ultra-high sensitivity at 100mV/V/Oe, along with excellent noise performance as low as 150pT /rtHz at 1Hz, in a compact LGA package as small as 4x4x2.5mm. They are best suited for high-end industrial sensor applications, biomedical sensor applications, precision measurement of magnetic field, high-precision speed and position sensing, geomagnetic sensing, metal object detection, non-destructive testing (NDT), magnetic communication, 3D magnetic imaging, etc.

“MDT’s new three-axis high-performance TMR magnetic sensors offer great versatility to many high-end applications that have already benefited from MDT’s TMR sensor technology, with outstanding low-noise, low-power and high-sensitivity performance that cannot be matched by any other semiconductor-based magnetic sensors, including Hall Effect, AMR (Anisotropic Magnetoresistance) and GMR (Giant Magnetoresistance). The new TMR23xx sensors integrate three high-performance TMR sensing devices for the X/Y/Z three-dimensional magnetic field measurement in a compact package or module. They provide the best option for our customers’ return-of-investment with small size, precise positioning of the X/Y/Z directions, reduced circuit complexity, and improved cost-effectiveness. Based on MDT’s in-depth expertise in design and manufacturing of TMR sensors, we can also offer custom designs of three-axis sensors that are specifically tailored to customer requirements,” said Dr. Song Xue , President and CEO of MultiDimension Technology.
