160-Position Board-to-Board Stacking Plug
The TE Connectivity 1-1734100-6 is a 160-position board-to-board plug from the CHAMP.050 I series, designed for high-density parallel PCB stacking. With two rows of center strip contacts and gold flash plating, it handles signal-level interconnects where position count per board edge is the primary constraint.
What the Gold Flash Plating Means for Signal Duty
Gold flash on the contacts provides a corrosion-resistant mating surface suitable for moderate mating cycle counts.
The CHAMP.050 I name signals a 0.050-inch (1.27 mm) pitch — a dense grid that packs 160 positions into a board edge footprint roughly 4 inches long. The two-row layout with center strip contacts means the PCB footprint uses staggered through-hole pads; the board lock adds two additional plated through-holes for the anchor posts. Verify the keep-out zone for the plug body height above the board — the mated stack height with the matching receptacle determines the clearance between parallel PCBs.
