A sensor unit for a rotational angle measurement system for detecting a rotational movement of a drive shaft includes a housing arrangement with a pot-shaped housing part, a carrier member, a sensor printed circuit board arranged on the carrier member, and a bearing which, in an operating state, mounts the sensor printed circuit board in a stationary manner in the housing arrangement with respect to the drive shaft. The bearing is a form fit/force fit arrangement so that the carrier member is movably mounted in the housing arrangement in a pre-assembled state.
