摘要：
The invention relates to an active magnetic field sensor, especially a wheel-bearing sensor unit, comprising at least one magnetic sensor element (10, 21, 36) for converting a temporally periodic magnetic field into a temporally periodic electrical sensor signal at signal outputs (37, 31); and an electronic signal evaluation circuit. The magnetic field sensor is supplied with electricity via a sensor interface. Periodic signals (38, 39) of the magnetic field sensor element are actively electrically processed in two or more separate signal channels of the evaluation circuit, allocated to the sensor signals, respectively.
