Magnetic sensors are devices that detect and measure magnetic fields, enabling critical functions such as position sensing, speed detection, current monitoring, and geophysical surveying across automotive, industrial, aerospace, and research applications. Eata Sensors offers a comprehensive range of high-performance magnetic sensing solutions, including Hall effect sensors, magnetoresistive sensors, fluxgate and magnetoinductive sensors, and precision magnetometers, all engineered to deliver exceptional accuracy, low noise, and reliable operation in even the most demanding environments.
Magnetic sensors are essential devices used to measure magnetic fields and detect changes in magnetic flux, enabling a wide range of applications across industries such as automotive, aerospace, consumer electronics, industrial automation, and geophysical exploration. These sensors operate on various principles, including Hall effect, magnetoresistive, fluxgate, and magnetoinductive effects, each offering distinct advantages in sensitivity, power consumption, and measurement range. From detecting rotational speed and position in motors to enabling non-contact current sensing and navigation systems, magnetic sensors provide reliable, contactless solutions that enhance system efficiency and safety. Their ability to function in harsh environments, resist contamination, and deliver precise measurements makes them indispensable in modern technology, supporting everything from electric vehicles and renewable energy systems to underground utility mapping and space exploration.

Hall Effect Sensors
Magnetoresistive Sensors
Magnetometers
Hall effect sensors detect the presence and strength of a magnetic field by measuring the voltage generated across a current-carrying conductor when exposed to a perpendicular magnetic field. These sensors are widely used for position sensing, proximity detection, speed measurement, and current sensing in automotive, industrial, and consumer electronics applications. They offer non-contact operation, fast response, good reliability, and tolerance to harsh environments, making them a cost-effective solution for high-volume applications.
Magnetoresistive sensors measure changes in electrical resistance when a magnetic field is applied to a ferromagnetic material. Available in AMR (anisotropic), GMR (giant), and TMR (tunneling) configurations, these sensors provide higher sensitivity and better temperature stability than Hall effect devices. They are ideal for precision applications such as angular position sensing, magnetic encoders, geolocation, and weak magnetic field detection in automotive, medical, and industrial automation systems.
Magnetometers are high-precision instruments used to measure the strength and direction of magnetic fields, including the Earth's natural field. Employing technologies such as fluxgate, optically pumped (e.g., cesium or potassium vapor), or magnetoinductive principles, these devices offer extremely low noise and high resolution. They are essential for geophysical exploration, archaeological surveying, unexploded ordnance (UXO) detection, space research, and magnetic anomaly mapping in marine, airborne, and terrestrial environments.
