Abstract
An electromechanical actuator has at least one electromagnet and an armature with a shank. The armature is mechanically coupled to at least one restoring device and it can move between a first bearing surface on the electromagnet and a further bearing surface. The shank is either completely hollow or it has a blind bore formed therein. A transmitter of a sensor is disposed in the cavity of the shank body.
