Abstract

Active sensor for switching over into a special operating mode, wherein the sensor has at least one sensor element, one evaluation circuit and two connecting lines, each with a terminal for transmitting the sensor information, wherein a supply voltage of the sensor is applied to the two connecting lines, wherein the sensor comprises a switchover module with which it is possible to switch over between a normal operating mode and a special operating mode by reversing the polarity of the supply voltage which is applied to the two terminals.A method for actuating an active sensor and to the use of the sensor, in particular as a wheel speed sensor, in motor vehicles.
