An electrical connector includes a dielectric housing and a plurality of electrical contacts carried by the dielectric housing. The electrical contacts can each define a mating portion that is configured to mate with a complementary mating portion of a complementary electrical connector. When the electrical connector is mated with a complementary electrical connector, a plurality of contact surfaces of the mating portions can contact a complementary mating portion, so as to establish an electrical connection between the electrical connector and the complementary electrical connector.
