Magnetic connector systems including a plug connector and a connector receptacle. In one example, the plug connector can include a magnetic target around a signal pin, where the signal pin is insulated from a plug enclosure by an insulating housing. The connector receptacle can include a magnet that is attracted to the magnetic target. The connector receptacle can contact the plug enclosure using one or more conductive springs. The one or more springs can deflect during an insertion of the plug enclosure. In another example, this deflection can act to expel moisture from the connector receptacle through drip holes in an enclosure for the connector receptacle.
