Abstract
A drug delivery assembly comprising a magnetic indicator and a sensor system is provided. The indicator is arranged to rotate and move axially relative to a housing component and corresponding to a reference axis, the amount of rotation being indicative of the size of an expelled dose amount. The sensor system comprises a sensor component adapted to measure a property of the indicator indicative of a rotational position and/or a rotational movement of the indicator. The sensor component forms part of release assembly adapted to be moved into engagement with a release member to release a set dose, and subsequently to move axially together with indicator.
