The Broadcom AEAT-9966 is a dual/redundancy angular magnetic rotary sensor provides accurate angular measurement over a full 360 degrees of rotation. A sophisticated system uses integrated Hall sensor elements with complex analogue and digital signal processing within a single device. A simple two-pole magnet generates the necessary magnetic field by rotating it in perpendicular. Wide magnetic field sensor configurations allow On Axis (end of shaft) or Off Axis (side of shaft, axial and radial) modes in application. The Broadcom It is a versatile solution capable of supporting a broad range of applications with its robust architecture to measure and deliver both absolute and incremental signals.
