— Continuous Magnetic Field Detection, ±5 Gauss High Sensitivity, andQuadrature A/B Outputs for Smart Utility Metering, Rotary and Linear PositionSensing, and Motion Control
ZHANGJIAGANG, China, July 13, 2026 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors and a pioneer in Tunneling Magnetoresistance (TMR) technology, today introduced the TMR1228D dual-axis bipolar latch magnetic switch IC. Combining always-on magnetic field detection, ±5 Gauss high sensitivity, microamp-level power consumption, dual-axis sensing, and high-frequency response, the TMR1228D is designed for smart utility metering, industrial position sensing, speed detection, and motion control applications.
The TMR1228D integrates high-sensitivity TMR sensing elements with CMOS signal-conditioning circuitry to convert changing magnetic fields into accurate digital output signals. Unlike conventional Hall-effect switches that rely on duty-cycled operation to reduce power consumption, the TMR1228D leverages TMR's inherent low-power characteristics to achieve continuous magnetic field detection while consuming as little as 1.5μA per axis. This eliminates missed detection events caused by intermittent sampling, delivering faster response and higher reliability for always-on sensing applications.The TMR1228D incorporates independent X- and Y-axis sensing channels with separate outputs, supporting industry-standard quadrature A/B signals for rotary and linear position, speed, and direction detection. This simplifies the design of motion sensing systems while providing greater flexibility for multi-axis magnetic detection.
