0.100" Pitch, 9-Position Unshrouded Header
The 94611-409HLF: This is a board-to-board style connector, through-hole mounted, with male square pins. Tin is the workhorse finish for moderate environments — it's cost-effective and reliable for a few hundred mating cycles, but in high-humidity or corrosive conditions, the tin surface can frett with repeated thermal cycling.
Mating and Fit Considerations
In a vibration-prone environment, a secondary locking method (like a wire-to-board housing with a latch) is worth considering. These dimensions matter for the z-height budget when stacking boards or fitting into a tight enclosure.
