AK09940 High-precision three-axis magnetic sensor
The AK09940 is a general-purpose digital output triaxial magnetic sensor IC using TMR technology with ultra-low noise and ultra-low power consumption. Sensors based on previous three-axis e-compass sensing solutions can increase magnetic 6-way free position tracking accuracy for AR, VR, MR, and wearable devices.
Ideal for magnetic particle testing and metal contamination detection, the AK09940 features a three-axis magnetic measurement that can measure wet fields, small changes, and distortions in magnetic fields with high accuracy. Magnetic position tracking, used in controllers such as AR and VR devices, has the advantage of being able to detect even if the sensor is hidden behind an object. However, due to signal noise on the receiving side, usually sufficient performance may not be obtained in terms of detection range, position accuracy, and response speed. This problem is solved by using an ultra-low noise triaxial magnetic sensor on the receiving side.
