The Anisotropic Magnetoresistive (AMR) 4-Pin Quadrature Sensor Integrated Circuit (IC) is designed to detect the speed, direction, and position of a ring magnet encoder target using a unique (patent pending) bridge design. The frequency of the output is proportional to the rotational speed of the target, and the rotational direction is encoded by the phase between the outputs. The sensor IC works over a wide range of speeds, temperatures and air gaps.
The VF401 is a high performance, digital, 2-wire, MR (magnetoresistive) sensor IC in a miniature, flat, TO-92-style, plastic package. Wide speed capability provides application flexibility with true zero speed sensing and operation up to 3000 Hz. Potential transportation, industrial and medical applications include those with speed encoding using a multipole ring magnet.
The VF526DT latching, dual Hall-effect digital position sensor IC has two distinct Hall sensing elements precisely located 1,4 mm [0.055 in] apart on a single integrated circuit chip. The two active Hall latches provide speed and direction indication of a magnetic gradient (such as a rotating ring magnet) across the face of the package. A unique, regulator circuit provides extremely stable operation with supply voltages from 3.4 Vdc to 24 Vdc. This product can directly interface with many electronic components without buffering or compensation circuitry.
