This header mates with Mini-Fit Jr receptacle housings (e.g., series 5557) using the corresponding crimp terminals. The 0.504\" (12.80mm) insulation height and 0.138\" (3.50mm) post length set the board-to-mating-half clearance. Row spacing is the same 0.165\" (4.20mm) as the pitch, so the footprint is a 2×6 grid.","metaTitle":"Molex 0039296128 Mini-Fit Jr Header, 12 Pos, Locking Ramp","metaDescription":"Molex 0039296128 Mini-Fit Jr 5566 header, 12 circuits, 4.20mm pitch, shrouded, locking ramp, gold contacts.
