AK09940
EOL
High Precision Tri-axis Magnetic Sensor
High Precision Tri-axis Magnetic Sensor
EOL
Description
Conventional tri-axis magnetic sensors have been used for position tracking applications. However, there are cases when sufficient performance is not possible due to magnetic field noise. World class ultra-low noise tri-axis sensing from the AK09940 resolves this problem, increasing magnetic position tracking accuracy for AR and VR. The AK09940 is ideal for magnetic particle testing and metal contamination detection with triaxial magnetic measuring, which measures wet field, small changes, and distortion in magnetic-fields with high precision. In addition, the AK09940 has very low power consumption current suitable for triaxial measurement in wearable and IoT devices with small batteries.
