The Amphenol 93939-460HLF is the 60-circuit dual-row member of the BERGSTIK II board-to-board header series, operating at 0.100" (2.54 mm) pitch and rated 5 A per contact. It mounts right-angle through-hole on the PCB, with square male pins that push-pull mate into the matching BERGSTIK II receptacle. The all-tin contact finish (100.0 µin thick on the mating face) and phosphor bronze base metal give this header its current and durability ratings for backplane and mid-plane stacking applications in industrial automation and telecom infrastructure.
The 93939-460HLF mates push-pull with the matching BERGSTIK II dual-row receptacle housing — the unshrouded pin header leaves the side walls open, which is typical for backplane mid-plane use where the receptacle polarises the assembly. The 0.190" (4.83 mm) insulation height and 0.160" (4.06 mm) contact length at mate define the engagement depth; the 0.120" (3.05 mm) tail length sets the board side penetration. Confirm the PCB pad stack accommodates the 2.54 mm pitch row spacing and the 0.100" row-to-row offset before committing to the layout.
Rated 110 V with tin contacts on both mating and post sides — the 100.0 µin (2.54 µm) tin finish on the mating face is below the gold plating grade used in high-cycle BERGSTIK variants. The black housing carries a UL94 V-0 flammability rating, the most demanding connector flame class, and is acceptable in enclosed equipment. The 5 A per-contact rating applies at rated current — if the application stacks multiple headers or runs continuous current, derate per the product thermal curve.
