Product details

The connector includes a board guide and a ground plate — the ground plate provides a low-inductance return path, which matters when routing high-speed differential pairs through the stack.

Stack height flexibility — one connector, two gaps

This plug supports mated stacking heights of 5mm and 8mm, meaning the same connector can be used in two different board-spacing designs without changing the BOM line.

Contact finish and mounting

Supplied in trays for pick-and-place handling.
