3D magnetic sensors
Infineon’s broad range of 3D magnetic sensors for applications requiring compact, high-accuracy solutions with low power consumption
A 3D magnetic position sensor is a valuable device that can detect the strength of a magnetic field on x-, y-, and z-axes. It can measure three-dimensional, linear, angular, and rotational movements and transmit the data via an output interface. 3D magnetic sensors can provide accurate measurements and only require a small amount of power to operate.
3D position sensors are also known as 3D Hall effect sensors, because they operate using Hall technology. The Hall effect, a longstanding method of magnetic field measurement, achieves measurable voltage by placing a magnet perpendicular to a flat conductor. Charge carriers – which carry current throughout the conductor – get disrupted by the magnet’s magnetic field, and their protons and electrons jump to opposite sides. With the positive and negative charges separated, a meter can quantifiably measure the conductor’s voltage.
A 3D Hall-effect position sensor linked with a magnet relays signals when the magnetic field’s power changes. Whether for determining proximity, angle, or rotation, changes to the magnetic field’s strength indicate position changes or abnormalities to the magnetic sensor via Hall effect, which then get sent to the operating system.
Infineon offers 3D magnetic hall effect sensors specifically designed for using in automotive, industrial, and commercial applications. Found in everything from gear shifts and joysticks to power tools and smart home appliances, we offer a broad range of sensors with features optimized for high-performance applications with respect to price and size. All products in the Infineon 3D Hall sensor family comprise of a small package, ultra-low power mode for low power consumption, as well as a standard 2-wire digital I²C interface.
Infineon XENSIV™ TLI493D-W2BW and TLV493D-A2BW 3D magnetic hall effect sensors offer particularly low power consumption, a compact footprint, and high-accuracy magnetic field measurement. With its small WLB package dimensions (1.13mm x 0.93mm x 0.59mm), TLV493D-A2BW is a miniature sensor suitable for system designs with low-space requirements, such as wearable devices and household products. With a low quiescent current of 7 nA in standby mode, this tiny 3D magnetic field sensor can offer extended battery life and battery charging cycles.
On the other hand, Infineon’s new XENSIV™ TLI493D-W2BW 3D sensor is blazing trails across new industrial and commercial use cases, powering human-machine interfaces like joysticks, pushbuttons, and appliances, and bringing enhanced position control to robotics. Using similarly limited power and providing an extremely small footprint output, its neighbor, the TLE493D-W2B6 3D magnetic sensor, contains a specific wake-up functionality that, by helping its overall system save power, proves especially valuable for battery-driven applications. This sensor is also suitable for high-safety applications, as it supports functional safety by means of integrated diagnostics.

Infineon magnetic 3-axis Hall effect sensors are gradually seeing more and more usage in automotivepplications. In automotive applications, these sensors enable control in the passenger compartment as well as under the hood with three-dimensional measurement capabilities and high-temperature range durability. The most common automotive use cases for 3D magnetic position sensors are in top column modules (TCM), gear sticks, and HDI functionalities, such as scroll wheels, seat adjustment, and H-Vac control. With linear magnetic range requirements that can be set up to ±160 mT, 3D sensors can also control elements for infotainment/navigation systems and multifunctional steering wheels.
3D magnetic sensors are also used in a number of industrial and commercial settings. Human-machine interfaces like joysticks and ergonomic pushbuttons rely on data generated by a 3D Hall effect sensor and magnet system. In labs and factories, 3D magnetic sensors allow for the precise control of robots and drones. They also bring anti-tampering protection to smart meters and have even made their way to individual products, now being used in domestic appliances, power tools, and wearable electronic personal care devices.
