The AEAT-9922 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360° of rotation
The AEAT-9922 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360° of rotation. It is a sophisticated system that uses integrated Hall sensor elements with complex analog and digital signal processing within a single device. A simple two-pole magnet generates the necessary magnetic field by rotating it perpendicularly. Wide magnetic field sensor configurations allow on-axis (end of shaft) or off-axis (side of the shaft) modes. The AEAT-9922 is a versatile solution that supports a broad range of applications with its robust architecture to measure and deliver both absolute and incremental signals.
