The Amphenol 79425-118HLF is a BERGSTIK® II unshrouded pin header, 18 positions in two rows on a standard 0.100" (2.54 mm) pitch. The 30.0 µin (0.76 µm) gold or Gold GXT™ plating on the mating surface handles repeated insertions without contact wear, while the UL94 V-0 rated black insulation housing keeps it compliant for equipment inside an enclosure.
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing land on a standard grid.
This unshrouded header mates with any standard 0.100" (2.54 mm) pitch dual-row receptacle or socket strip — typically a BERGSTIK® II or equivalent box header with 18 positions. The mating half provides the polarization and retention; the header itself has no shroud or keying.
