Magnetic metal detection
Tri-axis magnetic sensor, AK09940 is the most suitable sensor for measuring the minimum magnetic field in the nano-tesla range.
It can detect very small magnetic fields such as those generated by weak magnetic materials and the Villari phenomenon (reverse magnetostriction effect). The AK09940 is possible to detect a magnetic metal contamination and minute metal pieces at high speed. It also contributes to high accuracy and downsizing of inspection equipment, metal detectors.
