The TE Connectivity 2392557-1 is a Z-PACK A 22 backplane receptacle carrying 110 positions across 5 rows on a 0.079" (2.00 mm) pitch. It is a female socket connector designed for board-edge, right-angle mounting through press-fit termination — the compliant pin cold-forms into the plated through-hole without solder, which is the standard for backplane assemblies where rework and field-service reliability matter.
Press-Fit Termination and Right-Angle Orientation
Press-fit termination eliminates the thermal stress of wave soldering and allows the connector to be pressed into the backplane in a single operation. The board-edge mounting style means the connector sits at the edge of the backplane, with the press-fit tails extending through the board for the compliant pin interface.
The 500 VAC voltage rating provides adequate creepage for the 2.00 mm pitch in a backplane environment.
