AEAT-6010/6012 Magnetic Encoder 10 or 12 bit Angular Detection Device Data Sheet Description Features Avago Technologies’ AEAT-60xx series of magnetic • 10 or 12 bits resolution encoders provides an integrated solution for angular • Contactless sensing technologies detection. With ease of use in mind, these magnetic • Wide temperature range from -40° to 125°C encoders are ideal for angular detection within 360°. Based on magnetic technologies, the device is non-con- • Absolute angular position detection tact and ensures reliable operations. It is able to provide • Synchronous serial interface (SSI) output for absolute absolute angle detection upon power-up, with a resolu- position data (binary format) tion of 0.0879°(12 bits version) or 0.35°(10bits version), • Code monotony error = ± 1 LSB which is equivalent to 4096 and 1024 positions per rev- olution respectively. The positional data is provided in • 5V supply serial bit stream. There is no upper speed limit; the only • Easy Assembly, No Signal Adjustment required restriction is that there will be fewer samples per revolu- • RoHS compliant tion as the speed increases.
