An apparatus, comprising:

• a first connector portion comprising a first housing portion having a top surface and a bottom surface opposite the top surface of the first connector portion, the first connector portion further comprising at least a front surface and a first mounting portion extending from a top portion of the first connector portion and at least a second mounting portion extending from a bottom portion of the first connector portion;
• a second connector portion comprising a second housing portion having a top surface and a bottom surface opposite the top surface of the second connector portion, the second connector portion further comprising at least a front surface and a third mounting portion extending from a top portion surface of the second housing portion and at least a fourth mounting portion extending from a bottom portion of the second housing portion;
• a circuit board permanently coupled to the first housing portion of the first connector portion and permanently coupled to the second housing portion of the second connector portion;
• a first contact assembly coupled to the first housing portion of the first connector portion, the first contact assembly including a plurality of protrusions;
• and
• a second contact assembly coupled to the second housing portion of the second connector portion, the second contact assembly defining a plurality of recesses, each protrusion from the plurality of protrusions of the first contact assembly configured to be slidably received within a different recess from a plurality of recesses of a third contact assembly coupled to a third connector portion of a second apparatus distinct from the apparatus when the first connector portion is removably coupled to the third connector portion, each recess from the plurality of recesses of the second contact assembly configured to slidably receive a different protrusion from a plurality of protrusions of a fourth contact assembly coupled to a fourth connector portion of a third apparatus distinct from the apparatus and distinct from the second apparatus when the second connector portion is removably coupled to the fourth connector portion.
