5179029-6 is a fine pitch SMT stacking connector designed for parallel board-to-board applications with a 0.8 mm free height configuration. This connector is part of the 120-position connector family and features gold plating options of either 8 µ" Au or 30 µ" Au for enhanced durability and electrical performance. The connector has dimensional specifications of 55.20 mm (2.173 inches) for dimension A, 61.80 mm (2.433 inches) for dimension B, and 60.20 mm (2.370 inches) for dimension C. These connectors are commonly used in compact electronic assemblies where space constraints require minimal stacking heights while maintaining reliable board-to-board interconnection. The fine pitch design enables high-density signal routing in modern electronic equipment.
