1. An infusion pump system, comprising:

  • an infusion pump device having a reservoir receptacle to receive a reservoir containing infusion media and to selectively dispense the infusion media from the reservoir when the reservoir is received within the reservoir receptacle;

    the reservoir for containing the infusion media;

    at least one sensor element held by the infusion pump device;

    a connector interface to connect the reservoir with the infusion pump device, the connector interface comprising a cap to connect to the reservoir to form a reservoir/cap unit; and

    at least one magnetic detectable feature arranged on the cap for detection by at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in the reservoir receptacle of the infusion pump device,wherein the at least one magnetic detectable feature comprises a magnetic field angle of a magnet that is attached to a housing of the cap, the magnetic field angle being an angle of orientation of a magnetic field of the magnet relative to a predefined axis of the cap or the reservoir/cap unit, the magnetic field angle being non-parallel and non-perpendicular to the predefined axis; and

    wherein the at least one magnetic detectable feature is arranged at a location on the cap to be detected by the at least one sensor element when the reservoir or the cap of the reservoir/cap unit is in a fully installed and stationary position relative to the infusion pump device.
