Product Introduction

Semiconductor magnetoresistive devices (SMRs) are sensors that use the Lorentz force to cause changes in resistance values, and the principle is that the Lorentz force generated by electrons moving in a circuit through an external magnetic field increases the path of electron movement, resulting in an increase in resistance.
