AEAT-9922-102

AEAT-9922-102 is an 18bit programmable angular magnetic encoder IC for on and off-axis applications. It is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. It is a sophisticated system that uses integrated hall sensor elements with complex analogue and digital signal processing within a single device. 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. The incremental positions are indicated on ABI and UVW signals with wide user configurable resolution from 1CPR and up to 10,000 CPR of ABI signals and pole pairs from 1 to 32 pole pairs (2 to 64 poles) for UVW commutation signals. Typical applications are brushless DC motor and stepper motor, resolver and potentiometer replacement, industrial automation and robotics, industrial sewing machine and textiles equipment.
