AEAT-6010/6012 Magnetic Encoder
10 or 12 bit Angular Detection Device
Data Sheet
www.DataSheet4U.com
Description
Avago Technologies’ AEAT-60xx series of magnetic
encoders provides an integrated solution for angular
detection. With ease of use in mind, these magnetic
encoders are ideal for angular detection within 360°.
Based on magnetic technologies, the device is non-
contact and ensures reliable operations. It is able to
provide absolute angle detection upon power-up, with
a resolution of 0.0879°(12 bits version) or 0.35°(10bits
version), which is equivalent to 4096 and 1024 positions
per revolution respectively. The positional data is
provided in serial bit stream. There is no upper speed
limit; the only restriction is that there will be fewer
samples per revolution as the speed increases.
