Tunnelling Magneto Resistive Switch Sensors from MDT 

Multi Dimension Technology, a leading supplier of magnetic sensors specialising in Tunnelling Magneto Resistance (TMR) technology, has announced the world's first TMR magnetic switch sensors for use in battery-powered smart flow meters, including water flow meters, heat flow meters and gas flow meters.

Empowered by MDT's TMR technology, the new magnetic switch sensors are superior choices for high performance industrial applications, including proximity switches, speed sensors, and position sensors. TMR technology is proven as a high performance, power efficient, cost effective and dependable technology for the magnetic disk drive industry. MDT is the first volume supplier that offers all the advantages of TMR technology in multiple product series, including TMR magnetic switch sensors, TMR magnetic field sensors, and TMR magnetic angle sensors.

Dr. Song Xue, Chairman and CEO of Multi Dimension Technology explains :-
"MDT's new TMR magnetic switch sensors offer fast measurement, extended battery life, and uninterrupted, reliable operation to smart flow meters. We are passionate and devoted about introducing the benefits of TMR technology to the magnetic sensor market, and delivering products and solutions to promote the success of our customers."

The MMS103H and MMS105H magnetic switch sensors feature high frequency response up to 100kHz, and their supply current can be as low as 5 microamperes. Unlike similar products that must employ power cycling or sleeping modes to reduce power, MDT's magnetic switch sensors exhibit low power consumption during continuous operation.

Key Features

    • Bipolar TMR magnetic switch sensors with CMOS digital latching output
    • Operate and release points at +/-30 Gauss (MMS103H) and +/-50 Gauss (MMS105H)
    • High-speed magnetic field measurement at 100kHz frequency response
    • Low power consumption at 5 microamperes under 3V supply
    • Continuous operation for reliable measurement
    • Excellent temperature stability from -40°C to 125°C
    • TMR magnetic sensors and signal-processing ASICs integrated within a small SOT-23 or TO-92 package

Dr. Xue noted that MDT's TMR technology combines the key benefits of existing magnetic sensor technologies such as AMR (Anisotropic Magnetoresistance), GMR (Giant Magnetoresistance), Hall Effect, and Reed switch, while overcoming their critical limitations. As a result, MDT's TMR magnetic sensors provide a unique combination of high frequency response, low power consumption, high sensitivity, wide air-gap, endurance, and durability.

Multi Dimension Technology was founded in 2010 in Zhangjiagang, Jiangsu Province, China, with branch offices in Shanghai and San Jose, California, USA. MDT has developed a unique intellectual property portfolio, and state-of-the-art manufacturing capabilities that can support volume production of high-performance, low-cost TMR sensors to satisfy the most demanding application needs. Led by its core management team of elite experts and veterans in magnetic sensor technology and engineering services, MDT is committed to creating added value for its customers and ensuring their success.
