The TE Connectivity 1-5177986-2 is a 60-position plug from the Free Height (FH) series — a mezzanine board-to-board interconnect with center strip contacts. The 0.031" (0.80mm) pitch packs 60 circuits into two rows, making this a high-density option for parallel PCB stacking.
Stack Height Flexibility
The 0.230" (5.85mm) board height supports multiple mated stacking heights — 6mm, 10mm, 14mm, and 18mm — depending on the mating receptacle height selected. This range covers common mezzanine gaps from tight 6mm to generous 18mm, so the same plug can serve different board spacing requirements within a product family without a footprint change.
