Smart connection interface

A connector interface system, comprising:

• a reservoir to be received within a reservoir receptacle of an infusion pump device, the reservoir to contain infusion media to be selectively dispensed from the reservoir when the reservoir is received within the reservoir receptacle;
• 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;
• an infusion set coupled to the cap via a tubing for conveying infusion media dispensed from the reservoir;
• 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.
