TMR Current Sensor

Automotive & Industrial TMR Current Sensor - integrated busbar

Piher Sensing Systems launches  TMR current sensors generate a ratiometric analog output voltage signal proportional to the current flowing through the integrated conductor. Compared to conventional Hall-effect current sensors, These sensor provide more accurate measurement, excellent dynamic range, a higher sampling rate, lower temperature drift and superior sensitivity. They have been designed for accurate measurement of currents in automotive battery management systems,  renewable energy systems and motor control applications.

Our TMR sensors offer 1 MHz bandwidth, high linearity, high-resolution, clearer signals (higher signal-to-noise ratio), use less power, and perform consistently across a range of temperatures. This makes them exceptionally reliable and efficient.

Whether it’s in cars needing precise speed and position measurements, industrial machines requiring accurate current sensing, or consumer electronics aiming for better performance, Piher’s TMR sesnors are the perfect solution. They allows engineers and designers to create smaller, smarter, more accurate, and more efficient than ever before.
