BERGSTIK II Unshrouded Header — 18-Position, 0.100" Pitch
It uses a 0.100" (2.54 mm) square-pin grid on both the mating pitch and row spacing — a standard footprint that matches legacy and current board layouts.
Rated 5 A per circuit at 110 V, the 87052-118HLF is sized for signal-level and moderate power interconnects — think I/O, control, or low-current board-to-board links. The 5 A per-contact rating is typical for a 0.100" pitch header with phosphor bronze contacts; the limiting factor is the pin density and the PCB trace width, not the contact itself. The 30.0 µin (0.76 µm) gold plating on the mating surface gives good corrosion resistance and supports repeated mating cycles in non-sealed environments — a reasonable choice for field-serviceable assemblies. The 0.990" (25.15 mm) overall contact length and 0.120" (3.05 mm) post length mean it suits standard 1.6 mm PCBs; the post protrudes enough for a clean solder fillet on the back side without bottoming out against the board.
