— TMR Sensor Technology Achieves High-speed Operation, High Reliability, Outstanding Jitter Tolerance for Motor Control and Speed Sensing Applications

SAN JOSE, Calif. and ZHANGJIAGANG, China, August 2, 2016 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT) announced TMR3101, the first digital magnetic rotary encoder featuring Tunneling Magnetoresistance (TMR) sensor technology. The TMR3101 is a 10-bit high-speed rotary encoder with multiple absolute and incremental output interfaces. It is an ideal choice for motor control, rotary position and speed sensing applications including robotics, drones, smart meters, liquid level meters, smart door switches, and electrical toys, offering users enhanced ROI with accurate angular position measurement and relaxed requirement for the design of the magnet and mechanical structure.

“MDT’s new TMR3101 is the first digital absolute magnetic encoder product available on the market based on TMR technology. The TMR3101 offers new alternatives to existing magnetic encoder products with high reliability and outstanding jitter and air-gap tolerance, thanks to the unique technical advantages of our TMR technology. Based on MDT’s in-depth expertise in design and manufacturing of TMR sensors along with a strong IP portfolio, we are fully committed to provide greater value to customers. We offer a comprehensive set of product and service options, including TMR sensors in standard packages, wafers or bare-dice, custom package or module design services, or application solutions,” said Dr. Song Xue, President and CEO of MultiDimension Technology.

Key Features of TMR3101

- 360-degree contactless measurement

- Enhanced versatility in multiple high-speed output interfaces  SPI/PWM/ABI/UVW/PDI, with 10-bit continuous absolute mode output at 3000  RPM, or 1024-line incremental mode at 10000 RPM

- User programmable through the 4-wire SPI interface

- Pulse width variation less than 10%

- Large operating range allowing relaxed tolerance of air-gap or  mechanical jitter

- Fine resolution at 0.35 degree

- Operating temperature from -40 to +125 degrees Celsius

- Compact LGA package in 5x5x0.9mm


MDT's TMR technology realizes the key benefits of existing magnetic sensor technologies including Hall Effect, AMR (Anisotropic Magnetoresistance) and GMR (Giant Magnetoresistance), while adding the high sensitivity, high resolution, low power, and excellent thermal stability inherent in TMR technology. MDT offers all advantages of the TMR sensor technology to the commercial sensor market in a growing product portfolio, including TMR angle sensors, TMR magnetic switches, TMR linear magnetic field sensors, TMR gear tooth sensors, and TMR magnetic image sensors.
