Sensor element for revolution counter

摘要

The invention concerns a sensor element ( 11 ) designed in particular for a revolution counter ( 10 ). It is possible to pass a magnetic field in front of said sensor element ( 11 ). The latter ( 11 ) has a laminated structure ( 2 ) and a shape ( 30 ) such that power supply is not needed to cause a modification of magnetization in the sensor element ( 11 ) when the magnetic field passes in front thereof, and in that several such modifications can be stored.
