The first, the second, and the third sensing areas are provided with a first midline, a second midline, and a third midline in the direction of movement, respectively. The first and second midlines are symmetrical with respect to the third midline. The first and second sensing areas are jointly configured to output a first output signal. The third sensing area is configured to output a second output signal. A phase difference between the first and second output signals is 90 degrees, and the first and second output signals are jointly configured to determine the distance or the speed or the angle of movement and the direction of movement of the relative motion.

Abstract: A wheel speed sensor for a motor vehicle can be supplied with an operating voltage by a control device. The control device has a load resistance with a load resistance value. An operating voltage can be at a voltage input by the control device. An electrical circuit is designed to determine a turn-on or a turn-off voltage value according to the load resistance value. An operation control is designed to transfer the wheel speed sensor into a normal operation using the operating voltage, when the turn-on voltage value is exceeded, and to transfer the wheel speed sensor into an emergency operation using the operating voltage, when a turn-off voltage value is not met. In emergency operation only a low constant signal level is emitted.

Abstract: A method for transmitting error information of a sensor, in a signal exchanged between the sensor and a master receiver, said signal being designed with a minimum level for supplying electric power to the sensor and carrying measurement data. One disclosed method involves identifying the error in the sensor; switching off a component of the sensor consuming electric power; and transmitting the error information at an error level lying below the minimum level.
