64-Position Mezzanine Plug for IEEE 1386 PMC Modules
The plug mates with the corresponding Free Height receptacle to form a board-to-board stack at one of three supported heights: 9 mm, 11 mm, or 14 mm.
Stack Height Selection and Board Layout
The same 5120526-1 plug supports three mated stacking heights — 9 mm, 11 mm, and 14 mm — by pairing with different-height receptacles in the Free Height family. This lets a single plug BOM line cover multiple board-spacing requirements in a product family. The 0.039" (1.00mm) pitch demands a tight board layout; the dual-row 64-position footprint fits within the PMC standard keep-out zone. A board guide feature on the plug aids alignment during card insertion.
