The Amphenol BERGSTIK® II 79425-472HLF is a 72-position, dual-row unshrouded header on the standard 0.100" (2.54 mm) pitch. It carries tin-plated phosphor bronze male pins with a square contact shape, terminated by through-hole solder.
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing place this header on the legacy through-hole grid — the footprint matches standard 0.1-inch perfboard and many existing PCB layouts. The overall contact length of 0.410" (10.41 mm) breaks down as 0.190" (4.83 mm) mating length and 0.120" (3.05 mm) solder post length — the post length determines the PCB thickness the header can accommodate.
