Abstract
The invention concerns a rotation angle sensor, in particular a steering angle sensor (1) for a steering unit, with a housing (2) comprising an exterior (8), a pick-up sensor (7) arranged in a sensor chamber in the housing (2) to perform rotary movements around a rotation axis, and a stationary receiver interacting with the pick-up sensor (7). It is endeavored to make such steering angle sensors fit for rough environmental conditions. For this purpose, the sensor chamber is connected to the exterior (8) via at least one free space (16).
