DF59 2mm Pitch Connectors Hirose DF59 2mm Pitch Connectors feature an ultra low profile design that minimizes shadowing. These 2mm pitch connectors enable multiple wire-to-board, co-planar board-to-board bridge, and short-circuit pin connections to the PCB that minimizes the issue of thermal expansion. The floating board-to-board connector with stress-free contact allows ±0.5mm floating function in XYZ directions. Hirose DF59 2mm Pitch Connectors feature a positive swing-lock mechanism that provides strong plug retention against cable pull. These connectors are available in 2, 3, and 4 positions.
