The Amphenol BERGSTIK II 92634-420HLF is a 20-position, dual-row, unshrouded male pin header for board-to-board interconnect. It sits on the standard 0.100" (2.54 mm) pitch in both rows and between rows, making it footprint-compatible with the broadest class of 0.100" IDC sockets and mating receptacles. The right-angle through-hole termination places the pin row parallel to the PCB, suited for board-edge or mezzanine connections where the cable or mating board exits parallel to the main board.
Rated 5 A per circuit at 110 V, with a UL94 V-0 black housing. The 5 A rating is typical for a 0.100" pitch signal header — adequate for logic-level power and low-current signal distribution, but not for bus-level power rails. The tin-on-tin contact system (mating finish 100.0 µin tin over phosphor bronze, post finish tin) is cost-effective for applications with limited mating cycles — think one-time board assembly or infrequent field service. For higher cycle counts, a gold-plated variant in the same BERGSTIK II family would be the better call.
The 0.318" (8.08 mm) mating pin length and 0.318" (8.08 mm) post length give a standard through-hole footprint. The right-angle orientation means the board layout needs clearance behind the pin row for the solder tails — check the keep-out zone against your enclosure wall or adjacent components. The unshrouded design gives the board layout engineer flexibility in mating height and alignment, but provides no polarization keying; the mating receptacle must be aligned by the board pattern or a separate alignment feature.
