An electrical connector that includes a dielectric housing and at least one pair of signal conductors adapted to mate with a printed circuit board. The pair of signal conductors include first and second conductors. The first conductor includes a first mating portion, a first contact portion remote from the first mating portion, and a the intermediate portion therebetween. The second conductor includes a second mating portion, a second contact portion remote from the second mating portion, and a second intermediate portion therebetween. Each of the first and second mating portions define a mating portion axis and each of the first and second contact portions define a contact portion axis. The contact portion axes are offset from the mating portion axis.
