Abstract
A sensor unit for measuring a rotational state of a shaft may include a transmission. The transmission may be connected to or configured to connect to the shaft. The transmission may have at least two transmission elements that are in engagement with one another via a toothing. At least one of the at least two transmission elements is a gearwheel whose rotation about a rotational axis is detected by a sensor. The at least one gearwheel and the toothing arrangement of the at least one gearwheel may be formed by a printed circuit board. A track may be arranged on an end side of the gearwheel that faces the sensor, and the sensor may scan the track to measure a rotational state of the gearwheel about the rotational axis.
