It uses the standard 0.100" (2.54mm) pitch on both rows and between rows, so the footprint matches legacy perf-board and common 0.100" grid layouts.
What the key specs mean for fit
The 22 positions in two rows means the board footprint is 11 positions per row, which is a common count for parallel I/O or ribbon-cable interfaces. The 30.0 µ" gold plating is the key differentiator from tin-plated versions — it handles 100+ mating cycles without degradation, while tin would start showing wear after 25-50 cycles in a production environment.
The base product number 86840 covers the full BERGSTIK II family.
The right-angle through-hole termination requires the board to have 22 plated through-holes on 0.100" centers in two rows spaced 0.100" apart.
