AMS OSRAM GROUP AS5601-ASOT Contactless Encoder, 12bit Programmable, 4.5 to 5.5 V, -40 to 125 °C, SOIC-8

AS5601-ASOT is a 12Bit programmable contactless encoder. It is an easy-to-program magnetic rotary position sensor with incremental quadrature (A/B) and 12-bit digital outputs. Additionally, the PUSH output indicates fast airgap ranges between the AS5601 and magnet which can be used to implement a contactless pushbutton function in which the knob can be pressed to move the magnet toward the AS5601. This AS5601 is designed for contactless encoder applications, and its robust design rejects the influence of any homogenous external stray magnetic fields. Based on planar Hall sensor technology, this device measures the orthogonal component of the flux density (Bz) from an external magnet.Industry-standard I²C interface supports user programming of non-volatile parameters in the AS5601 without requiring a dedicated programmer. The AS5601 is ideally suited for encoder replacement, contactless rotary knobs with push buttons, other angular position measurement solutions.
