Abstract

An angular position sensor may include a housing, and a rotor including a rotor assembly with a rotor latching device. The rotor and the housing are connected by the rotor latching device secured by a retaining ring. The retaining ring can be transferred into a secured position in an axial direction. The retaining ring is integral with the rotor assembly and features at least one retaining element with which the retaining ring secures the connection of rotor and housing. The retaining ring and the rotor latching device each feature corresponding latching elements. The rotor assembly features axial position-securing elements. The latching elements interact such that the retaining ring is secured in an axial direction along the rotary axis relative to the rotor. The axial position-securing elements interact so that the rotor is secured essentially free of play on the housing in an axial direction along the rotary axis.
