The Amphenol 68438-172HLF is a 72-position unshrouded male pin header from the BERGSTIK® II series, a workhorse board-to-board interconnect family. It carries two rows on a standard 0.100" (2.54mm) pitch with a matching 0.100" row spacing, rated 5A per contact at 110V. The mating surface is finished with 30.0µin (0.76µm) gold or Gold, GXT™ over phosphor bronze — a plating grade that supports repeated mating cycles in corrosive or field-service environments. The through-hole solder termination and 0.225" (5.72mm) post length suit it for conventional wave-solder assembly on standard-thickness PCBs.
The header is unshrouded with a push-pull fastening type, so it relies on the mating receptacle's retention features for lock-in — suitable for applications where the connector pair is not subject to high vibration or where a secondary locking mechanism is used. The housing carries a UL94 V-0 flammability rating, meeting the enclosure-level fire safety requirement for equipment inside industrial or commercial enclosures. All 72 positions are loaded, giving the full circuit count for a 72-conductor interface.
