10-Position Dual-Row SMT Receptacle at 1.27mm Pitch
The 20021321-00010C1LF: The SMT termination and pick-and-place feature mean it's reflow-ready for automated assembly.
Gold Flash Contacts for Moderate-Duty Interconnect
The mating contacts are gold flash over phosphor bronze. Gold flash provides corrosion resistance and a stable contact interface for routine board mating — think one or two assembly cycles plus occasional field rework.
Gold Thickness Variant for Higher Cycle Life
If your application requires more than a handful of mate/unmate cycles — say, a test fixture or a module swapped quarterly — the 10.0µin gold provides measurably better wear resistance. For a one-time board stack that stays mated, the flash version is sufficient.
