MPS9WGW

Magnetic sensors (modules) are used extensively in almost every industrial field and industrial product as these devices are used to sense and measure the presence of magnetic fields. This article discusses the application field and working principle of MPS9WGW, a magnetic sensor module manufactured by Murata.

Application field of MPS9WGW

MPS9WGW is a highly reliable magnetoresistive module designed to measure the direction and magnitude of magnetic fields and is used in a wide variety of industrial and commercial applications. It can be used to measure the magnetic field in vehicles, medical equipment, robotics, aerospace, and power transformers, among other applications. In vehicles, it can detect the direction of the magnetic field generated by Earth’s magnetism, enabling driverless navigation. In medical equipment, it can measure the amount of energy produced by an MRI or CT scan. In robotics, it can detect and measure the position of an object or robot arm, providing feedback on the robot’s movements. In power transformers, it can detect and measure the field produced by the magnetizing current, allowing for greater accuracy in the measurement of the current.

Working principle of MPS9WGW

MPS9WGW works on a principle known as magnetoresistive sensing. When a magnetic field is applied, the electrons in the material become aligned with that field, thereby changing the material’s electrical resistance. The change in resistance is then detected by the sensor and used to measure the magnetic field. MPS9WGW utilizes a custom magnetoresistive sensing element and a signal processing circuit to enable precise, accurate, and low-noise measurements with minimal power consumption and a high temperature range.

MPS9WGW can detect magnetic fields from 10 microteslas up to 200 milliteslas with an accuracy of 0.5 mT. It is also capable of detecting the direction of the magnetic field, allowing for driverless navigation. The module comes with a 4-pin connector that is used for power input as well as for outputting the data for further use.

Conclusion

MPS9WGW is an accurate and reliable magnetoresistive module that is used in a wide variety of applications, including vehicle navigation, medical scanning, robotics, aerospace, and power transformers. It utilizes magnetoresistive sensing to detect and measure the magnetic field with an accuracy of 0.5 mT and a range of 10 microteslas up to 200 milliteslas. It also allows for the detection of direction of the magnetic field.
