Abstract

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.
