Description
Avago Technologies’ AEAT-60xx series of magnetic encoders offers a comprehensive solution for angular detection, suitable for 360° applications. These encoders utilize non-contact magnetic technologies, ensuring reliable operation and absolute angle detection upon power-up. The 12-bit version provides a resolution of 0.0879° (4096 positions per revolution), while the 10-bit version offers 0.35° (1024 positions per revolution). Positional data is output in a serial bit stream, with no upper speed limit, although higher speeds result in fewer samples per revolution.
