Abstract: A novel high density receptacle is disclosed. The receptacle includes a housing portion, having a plurality of openings formed in its front face. A first column containing a first number of contact elements is positioned in relation to the housing so that the receiving portions of the contact elements are aligned with certain of the openings. A second column containing a second number of contact elements is positioned in relation to the housing so that the receiving portions of the contact elements are aligned with other of said openings. It is preferred for the receptacle to include a plurality of said first and second columns, wherein the columns are arranged side by side in an alternating pattern. The first column preferably includes a first wafer, wherein the contact elements are attached to said first wafer. A peg is formed on one of the side surfaces of the first wafer. The second column is preferably constructed similar to the first column, however, the second wafer to has a bore formed therein.
