It's a board-to-board interconnect on a standard 0.100" (2.54 mm) pitch, dual-row layout with 0.100" row spacing — a footprint that matches the classic 0.1" grid for straightforward PCB layout.
What the key specs mean for the board
Rated 5 A per contact with tin-on-tin mating surfaces — the 100.0 µ" (2.54 µm) tin plating on the mating end is thick enough for a solid number of insertion cycles in a production or field-service environment, but tin is a soft finish. If the application calls for frequent reconnection (50+ cycles), gold-plated siblings in the BERGSTIK II range would be the better call. The 110 V voltage rating and UL94 V-0 housing suit general-purpose digital and low-power analog boards inside enclosed equipment. That keeps the cost down and the footprint small, but there's no keying or polarization, so the mating receptacle needs to be aligned visually or by board-edge registration. The 0.530" (13.46 mm) overall contact length breaks down as 0.320" (8.13 mm) mating length and 0.110" (2.79 mm) post length — the post is on the short side, so the PCB hole depth and solder fillet height need checking if the board is thick or has a heavy ground plane.
