Concerned about durability under tough conditions? Rest assured, TMR sensors are engineered for high-bandwidth applications, enabling them to handle rapid fluctuations and challenging environments with ease.

Newer models also feature compact designs, thanks to back-end-of-line (BEOL) manufacturing compatibility.

But how do they compare to traditional Hall-effect sensors? The difference is significant.

TMR sensors leverage changes in electrical resistance to achieve greater sensitivity and stability, making them a standout choice for applications where precision and efficiency are non-negotiable.

From automotive and renewable energy to heavy-duty industrial automation, TMR sensors are fast becoming the preferred solution for industries requiring accurate, power-efficient, and durable sensing technologies.

Looking to enhance accuracy, save energy, and tackle environmental challenges—all within a compact design? TMR sensors are paving the way for today’s designs and tomorrow’s innovations.
