AEAT-9955 Datasheet | Broadcom

Description The Broad® AEAT-9955 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. This sophisticated system uses integrated Hall sensor elements with plex analog 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 AEAT-9955 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 absolute angle measurement provides an instant indication of the magnet’s angular position with a selectable and reprogrammable resolution from 10 to 18 bits. When selected, its positioning data is then represented in its digital form to be assessed through a standard SSI (parity) and SPI (with CRC and Parity option) munication protocol. Where desired, users may also choose to receive its absolute angle position in PWM-encoded output signals. The incremental positions are indicated on ABI and UVW signals with a wide user-configurable resolution from 1 CPR to 20,000 CPR of ABI signals and pole pairs from 1 to 32 pole pairs (2 to 64 poles) for UVW mutation signals.
