High Sensitivity Series
This is a product in which the MI sensor element and drive circuit are mounted on a board, enabling highly sensitive magnetic measurement. It is supplied as a single board, so it can be placed in a case of any shape.
Type DJ
This sensor has the highest magnetic resolution (detection power) among MI sensors. It can detect magnetic field changes on the order of nT, 1/50000 of the geomagnetic field.
Type DW
This linear output magnetic sensor has a magnetic resolution close to that of the Type DJ and can also measure magnetism at the geomagnetic level.
Type DH
The detection of small ferrous metals on the order of 1/10mm in diameter is possible, and it is used for the detection of ferrous foreign matter in industrial products such as food, apparel products, and other non-magnetic products.
Type DF
This magnetic sensor can measure minute magnetic changes even in strong static magnetic fields. Only AC signals are detected by eliminating static magnetic field signal components stronger than the geomagnetic field.
Type DM
One-axis linear output magnetic sensor.
The measurement range is ±300μT, and the response is from DC to 10kHz.
Compact Series
The digital output type features an ultra-compact product that integrates 3 MI sensors for sensing magnetism in three directions and a control IC for operating the sensor. More than 140 million electronic compasses (geomagnetic sensors) using this product are used worldwide.
AMI306M
Applied products
Three types of application products using MI sensors.
By using these sensors, magnetic measurement using the MI sensor and calibration of the magnetic sensor can be performed easily.
