A31316 3D Hall-Effect Magnetic Position Sensor IC Allegro MicroSystems A31316 3D Hall-Effect Magnetic Position Sensor IC is designed for on-/off-axis rotary and linear stroke position measurement in automotive, industrial, and consumer applications. The robust sensor IC integrates vertical and planar Hall-effect elements with precision temperature-compensation circuitry to detect two of three magnetic field components (X, Y, and Z). Configurable signal processing, linearization, and angle calculation allow the A31316 to accurately resolve the absolute rotary (full 360° and short stroke <,360°) or linear position of a moving magnetic target.
