1. A rolling bearing comprising:
two bearing rings;
rolling elements running between the two bearing rings; and
a sensor for detecting movements and/or positions of the two bearing rings relative to one another,
wherein the sensor is fastened to one of the two bearing rings and is directed towards a measurement surface on the other of the two bearing rings, wherein the measurement surface comprises a contour projection projecting towards the sensor and/or a contour recess open towards the sensor in the form of a groove or a blind hole, wherein the contour projection and/or the groove influences a measurement signal of the sensor and the movement of which relative to the sensor transverse to a main signal direction of the sensor modifies the measurement signal of the sensor,
wherein the contour projection and/or the contour recess has two contour portions made of different materials and that are configured to generate different sensor signal responses.
