All 38 positions are loaded, giving you 19 pins per row for signal or low-current power distribution. Rated 5A per contact at 110V, with 30.0µin (0.76µm) gold or GXT™ plating on the mating surface. The phosphor bronze contacts and UL94 V-0 rated black insulation handle the thermal and flame requirements of equipment inside an enclosure.
Within the BERGSTIK® II family, the 79425-138HLF sits at 38 positions in a 2-row layout. The closest sibling in the same series is the 79425-136HLF at 36 positions — same 0.100" pitch, same dual-row footprint, same 5A rating. The decision between them is purely a circuit-count match to the BOM: the 38-position variant gives you two extra signal lines without changing the board layout pitch or the mating receptacle family.
