Magnetic metal detection

USE CASES
Video #01

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.

Demo videos show metal detection, detection mechanism, application, and demo kit.A

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
AK09940 use TMR element
It can detect "nT" order 3D magnetic field

#03

What application is it?

Detect a stapled booklet
Nopaper feed error by staple
Detect a metal in the food
Novisual check
Detect a dangerous goods like knife
For security gate of airport etc...
