The Amphenol FCI BERGSTIK II 92417-404HLF is a dual-row, unshrouded male pin header with 4 positions on a 0.100" (2.54 mm) pitch — the standard 0.100" grid that matches legacy perfboard and prototyping layouts. It's a board-to-board interconnect, typically soldered into a PCB as the plug half, mating with a matching 0.100" pitch receptacle or female header.
The 0.100" (2.54 mm) pitch is the bread-and-butter spacing for through-hole headers — your board layout uses a 0.100" grid, and the 0.100" row spacing keeps the two rows aligned to standard perfboard or proto-typing matrix. The 0.320" (8.13 mm) mating pin length gives enough reach to engage a standard receptacle housing, while the 0.110" (2.79 mm) solder post length suits a typical 1.6 mm PCB thickness with a through-hole solder joint. Overall contact length is 0.530" (13.46 mm).
Tin-plated contacts are rated for fewer mating cycles than gold, but the 100.0 µin thickness is heavier than the typical flash tin, so it holds up better under vibration and fretting in a permanent install. The phosphor bronze base material provides decent spring retention.
Unshrouded design
This simplifies board layout and reduces cost, but there's no polarization key or mis-mate protection. For a low-vibration bench or enclosure interior, the unshrouded style is standard.
