AEAT-6010/6012 magnetic encoder 10 or 12 bit angular detection device data sheet 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-con- tact and ensures reliable operations. it is able to provide absolute angle detection upon power-up, with a resolu- tion of 0.0879(12 bits version) or 0.35(10bits version), which is equivalent to 4096 and 1024 positions per rev- olution 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 revolu- tion as the speed increases. exploded view features ? 10 or 12 bits resolution ? contactless sensing technologies ? wide temperature range from -40 to 125c ? absolute angular position detection ? synchronous serial interface (ssi) output for absolute position data (binary format) ? code monotony error = 1 lsb ? 5v supply ? easy assembly, no signal adjustment required ? rohs compliant applications ? flow meter ? angular detection ? knob control ? rotary encoder note: this product is not specifi cally designed or manufactured for use in any specifi c device. customers are solely responsible for determining the suitability of this product for its intended application and solely liable for all loss, damage, expense or liability in co nnection with such use. magnetic encoder motor plastic housing sensor pcb assembly plastic hub plastic base plate 2 x screws customer magnet snap ring
