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.

Tri-axis Magnetic Sensors

#01

What is this Demo?

  • Smallness metal (staple)
  • It's difficult to detect
  • But this Demo kit can easily detect !

#02

How to detect?

  • Generates ACMagnetic field
  • When user move metal closer to coil,
  • It generates ultraweak magnetic field
  • Sensor detects this magnetic field change
