ZHANGJIAGANG, China, July 13, 2026 /PRNewswire/ — [MultiDimension Technology](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4729115-1&h=3578088050&u=http%3A%2F%2Fwww.dowaytech.com%2Fen%2F&a=MultiDimension+Technology)
Co., Ltd. (MDT), a leading supplier of magnetic sensors and a pioneer in Tunneling
Magnetoresistance (TMR) technology, today introduced the [TMR1228D](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4729115-1&h=1925423304&u=https%3A%2F%2Fwww.dowaytech.com%2Fen%2FTMR1228-TMR-Switch-Sensors.html&a=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.

With ±5 Gauss operating and release points, the TMR1228D enables the use of smaller
magnets, wider air-gaps, and greater mechanical design flexibility. For applications
requiring stronger magnetic fields or different magnet configurations, MDT also 
offers the [TMR1222D](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4729115-1&h=644568081&u=https%3A%2F%2Fwww.dowaytech.com%2Fen%2FTMR1222-TMR-Switch-Sensors.html&a=TMR1222D),
featuring ±17 Gauss operating thresholds in the same package and pinout to support
a broader range of mechanical structures and magnetic circuit designs.

The TMR1228D is ideal for electronic water, gas, and heat meters, quadrature encoder
systems, rotary and linear position and speed sensing, and other battery-powered
or always-on sensing applications.
