The AEAT-9955 is a sophisticated angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. It integrates Hall sensor elements with complex analog and digital signal processing within a single device. The system supports both On-Axis and Off-Axis configurations. It offers user-configurable absolute resolution from 10 to 18 bits via SSI, SPI, or PWM interfaces, and incremental positions via ABI and UVW signals with up to 20,000 CPR.
