Contact Interface: 30µin Gold for Repeated Mating
The 66506-066LF: The contact shape is square male pin, typical for a standard pin header interface that mates with a receptacle using dual-beam or tuning-fork contacts.
Peer Comparison: 10 vs 14 Positions
The closest functional sibling is 66506-001LF — identical in pitch, plating, shroud, and termination, also 10 positions and black insulation. The only difference is the order-code suffix; both are active and RoHS compliant. For a higher circuit count, 66506-038LF offers 14 positions in the same 0.100" pitch, dual-row layout, and 30µin gold finish — the board footprint simply extends by two columns.
