The mated stack height of 2 mm (with a 1.60 mm height above board on this plug side) sets the z-axis clearance between two parallel PCBs, so the total envelope fits inside a tight enclosure. The outer shroud contacts mate with the matching SlimStack receptacle to form a low-profile, surface-mount connection. Gold finish on the contacts (10.0 µ\" thickness) handles moderate mating cycles in controlled, indoor environments — enough for production test points or field-serviceable modules, but not for high-wear automotive or corrosive atmospheres. For a 30-circuit dual-row layout, you're looking at a 15-pin-per-row pattern that fits in about 7.5 mm of board edge. The 2 mm mated stack height is a specific z-height class: it pairs with the matching SlimStack receptacle to give exactly 2 mm of clearance between the two PCBs. If your enclosure has a different board spacing, you'll need a different stack height variant in the 55650 family. The 30-position count matches a 30-circuit BOM line for a parallel signal bus or a dense I/O interface. At 0.50 mm pitch, each contact is rated for signal-level current — the narrow spacing limits per-contact current well below what a 2.54 mm pitch header would carry. This connector is for signal routing, not power distribution.","metaTitle":"Molex SlimStack 0556500388, 30 Pos, 0.50mm Pitch","metaDescription":"Molex 0556500388 SlimStack 55650 plug, 30 circuits, 0.50mm pitch, 2mm stack height, SMT, gold plating.
