The 0022284012: The single position makes it a breakaway segment — useful for test points, programming headers, or single-wire power/signal connections where a multi-position header would waste board space.
Tin Plating at 100 µinch — Mating Cycle Reality
Both the mating and post finishes are tin at 100 µinch thickness. Tin is the workhorse finish for cost-sensitive, moderate-duty interconnects — expect 25–50 mating cycles before fretting corrosion becomes a concern in high-vibration environments. The square contact pin (0.025" square typical for KK254) mates with standard KK254 crimp terminals.
Flame Rating and Housing Material
This is required for equipment inside enclosures that must meet IEC 60950 or UL 62368 safety standards.
