New TMR Sensors Enrich MDT’s Rotary Sensor and Encoder Product Portfolio, Offering Customers Flexible Choices to Best Suit Their Needs

San Jose, Calif., and Zhangjiagang, China – Dec. 1st, 2021 – MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, has released the TMR4Mxx magnetic geartooth sensors for gear pitches in 0.2/0.3/0.4/0.5/0.8-module. They offer unique performance characteristics with high precision, large airgap tolerance and high-speed operation for rotary position and speed sensing in industrial applications including electrical spindle drives, CNC machines, servo motors, and elevators.


“TMR4Mxx are the underlying sensing components of MDT’s GE-T/GE-A geartooth encoders. As they have steadily gained recognition and popularity as MDT’s proprietary TMR-based geartooth encoders on the market, we release TMR4Mxx to assist customers who prefer taking sensor ICs and making their own designs. They are an extension to MDT’s TMR40xx series, the metric-system geartooth sensors that have been supplied in volume for 10 years. All MDT’s TMR geartooth sensor and encoder products share our TMR technology’s common qualities, including high signal-to-noise-ratio, high resolution for small pitch detection, large air-gap tolerance, and excellent temperature stability and immunity to interference, thanks to MDT’s unique TMR sensor design, leading-edge IP portfolio, and in-depth expertise in high-volume production.” said Dr. Song Xue, Chairman and CEO of MultiDimension Technology. “We provide a comprehensive product portfolio for geartooth rotary position and speed sensing applications, and let customers choose the best suitable way to realize the benefit of our TMR technology in their products. Whether they need fully-integrated rotary encoder modules, or they would rather take appropriate sensor ICs and design their own solutions, MDT will always be a dependable supplier and partner who is capable of expediting their design cycle and time-to-market with the a feature-rich product selection that closely matches the requirement and is readily available to the market.”

MDT’s geartooth sensors and encoders are available in the following product series. Please contact MDT for sampling, pricing and delivery inquires.
