22-Pin Unshrouded Header for Board-to-Board Stacking
The 54202-G3011LF: The unshrouded design (no plastic shroud around the pins) gives the mating receptacle direct access to the square pins, keeping the mated stack height low.
Gold Mating Finish and Surface Mount Termination
The mating surface carries 30.0 µinch (0.76 µm) gold over nickel — a plating grade that supports 500+ mating cycles in typical use. For a field-service connector cycled quarterly, that translates to over a century of reconnect life at the contact interface.
