The 10027011-106HLF: The header is a breakaway design, meaning the 6-position strip can be snapped from a longer strip during assembly.
What 30.0 µin Gold Means for Reliability
For applications requiring frequent field reconnection, the same gold layer reduces insertion force variation over life compared to tin-plated contacts. The contact base metal is phosphor bronze, which offers good spring properties and fatigue resistance for the cantilever beam of the mating receptacle.
Comparing Gold Thickness: 30 µin vs 15 µin
The 30.0 µin version (10027011-106HLF) provides roughly double the mating-cycle endurance — a meaningful difference if the connector lives in a field-service panel that sees quarterly reconnects over a decade. The choice between them hinges on the required reconnection duty and environmental exposure, not on electrical performance.
