50-Position, 0.100" Pitch, SMT Header
The SMT termination keeps the solder joints on the same side as the components, which simplifies the reflow profile compared to a through-hole variant. The connector mates with a matching Quickie™ receptacle (board-to-cable/wire style) and uses a latch lock/eject hook system for positive retention — the hooks click into the receptacle housing and resist vibration-induced disconnect.

The tin post finish is standard for solderability.
Peer Comparison: 50 vs 20 Positions
For a lower pin-count BOM line, the 20-position version saves board space and cost. The 50-position version here is the high-density option for signal-heavy harnesses. Another sibling, the 53611-G50-4LF, is a through-hole version of the same 50-position, 0.100" pitch header. If your assembly process prefers through-hole reflow or wave solder, that part is a direct drop-in replacement for the board footprint — the pin layout is identical.
