The MX8681R is a high performance magnetic sensor from Japanese technology company Melexis. It features a low power consumption, small footprint, and excellent sensitivity for linear and compass applications. The sensor is well suited for use in a variety of applications such as navigation systems and other similar devices. This article will discuss the application field and working principle of the MX8681R magnetic sensor.

Application Field

The MX8681R magnetic sensor provides a solution to a variety of measurement and sensing needs. It is well suited for use in navigation systems, robotics, magnetically-shielded networks, and collimators. It is also suitable for applications such as head-axis tracking, magneto-inertial navigation systems (MINS), magneto-infrared navigation systems (MINS), and ultra wideband (UWB) location systems. Additionally, this magnetic sensor can be used for automated position tracking and other similar tasks. Its low power consumption and small size make it ideal for mobile applications as well as embedded systems.

Working Principle

The MX8681R magnetic sensor uses an integrated collection of Hall effect circuits to detect variations in magnetic fields. The Hall effect principle is based on the observation that when a conductor is exposed to an external magnetic field, the charges within the conductor will move in a particular direction, creating an electrical current. With the MX8681R, a number of Hall effect circuits are integrated into one device, providing improved sensitivity. The Hall effect circuits are connected to two sensing elements, which are placed side-by-side on the same chip. The two sensing elements are then connected to sense amplifiers, which measure the difference in the voltage levels at the two sensing elements to generate a monotonic output, thus allowing the sensor to measure the relative angle of the magnetically-shielded field. The MX8681R magnetic sensor accurately measures a wide range of linear distances and angles, from short to long.

Conclusion

The MX8681R magnetic sensor from Melexis is an ideal solution for measuring linear distances and angles in a variety of applications. Its low power consumption, small size, and excellent sensitivity make it well suited for use in navigation systems, robotics, magnetically-shielded networks, and other similar devices. It is also well suited for use in head-axis tracking, magneto-inertial navigation systems, magneto-infrared navigation systems, and ultra wideband location systems. The MX8681R uses an integrated collection of Hall effect circuits to detect variations in magnetic fields and generate a monotonic output, allowing for accurate measurements of linear distances and angles.
