In a first embodiment, an elastomeric connector may include conductive and nonconductive portions and a guide that at least partially surrounds the connector and transfers compression in at least two directions. In a second embodiment, an elastomeric connector includes conductive portions at least partially surrounded by a nonconductive portion that is at least partially surrounded by conductive material connectible to ground to shield. In a third embodiment, an elastomeric connector may include multiple conductive portions and a nonconductive portion. One of the conductive portions may be separated from a first other in a cross section of a first connection surface and a second one of the others outside the cross section. At least one of the conductive portions may be connected to at least one of the others within the connector. In a fourth embodiment, a sealing component may include conductive and nonconductive elastomeric material.
