Magnetic angle sensor has two magnetic transducers over toothed magnetic disc to give differential output to flip flop circuit

摘要

A magnetic angle sensor has a second magnetic transducer (2b) on a center line through the magnet (3) and moving toothed magnetic disc (1) so that magnetic impedance variations give a differential output between the first (2a) and second magnetic sensors with a trough (5a, b) magnetic guide (5) between the differential flip flop processing circuit and the magnet.
