News Highlights: MultiDimension Technology Co., Ltd. (MultiDimension Technology Co., Ltd. -MDT) announced the world's first TMR magnetic switch sensor for battery-powered smart flow meters, including water meters, heat meters and gas flow meters.

This new magnetic switch sensor is powered by Multidimensional Technology's TMR technology (Tunnel Reluctance) and is the best choice for a wide range of high-performance industrial applications including proximity switches, speed sensors and position sensors. TMR technology has been proven to be a high-performance, cost-effective, low-power, and highly reliable technology in the disk drive industry. MDT is the first bulk supplier to offer all the benefits of TMR technology in its multiple product lines. These product families include TMR magnetic switch sensors, TMR magnetic field sensors, and TMR magnetic angle sensors.

Dr. Xue Songsheng, Chairman and CEO of Multidimensional Technology, said: “MDT's new TMR Magnetic Switch Sensor brings fast measurement, longer battery life, and continuous and reliable operation to smart flowmeters. We are fully committed to the TMR technology. The advantages come to the magnetic sensor market and help our customers succeed by introducing products and solutions."

The MMS103H and MMS105H magnetic switch sensors have a frequency response of up to 100kHz, while the supply current can be as low as 5uA. Unlike competing products that must use intermittent power or sleep mode to reduce power consumption, MDT's magnetic switch sensors can achieve low power consumption in continuous operation.

Important Features ● Bipolar TMR magnetic switch sensor with CMOS digital latch output ● Operating point and release point are /-30 Gauss (MMS103H) and /-50 Gauss (MMS105H)

● High-speed magnetic field measurement with frequency response up to 100kHz ● Power consumption as low as 5uA at 3V voltage supply ● Continuous operation to ensure reliable measurement ● Excellent temperature stability at -40 to 125°C range ● TMR magnetic sensor and Signal processing ASIC integrated in the small SOT-23 or TO-92 package Dr. Xue said that MDT's TMR technology covers AMR (anisotropic magnetoresistive), GMR (giant magnetoresistive), Hall effect, and reed switches. There are major advantages of magnetic sensor technology and overcome the important limitations of these technologies. Therefore, MDT's TMR magnetic sensors uniquely combine high frequency response, low power consumption, high sensitivity, wide measurement gap, durability, and durability.
