AS5601-ASOM

AS5601-ASOM is a 12bit programmable contactless encoder. It is an easy-to-program magnetic rotary position sensor with incremental quadrature (A/B) and 12bit digital outputs. Additionally, the PUSH output indicates fast airgap changes between the AS5601 and the 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. It 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. The application includes encoder replacement, contactless rotary knobs with push buttons, and other angular position measurement solutions.
