Allegro MicroSystems ALS31300 3D Linear Hall-Effect Sensors offer 3DMAG™ technology and provide a 12-bit digital value corresponding to the magnetic field measured in each X, Y, and Z axes. The devices are preconfigured for 3D sensing applications for head-on linear motion, slide-by position sensing, and rotation angle measurements. The ALS31300 offers a joystick mode, including a low gain option for the Z-axis channel. This feature employs a back-bias magnet to permit return-to-zero force instead of traditional spring-based solutions. Three different factory-programmed sensitivity ranges are available in ±500G, ±1000G, and ±2000G.
