The 2314918-8: The 125V rating covers most low-voltage signal and power distribution inside equipment — think control boards, sensor interfaces, or low-current I/O where the board-to-board span is short.
Mating Interface and Cycle Life
The gold thickness — 30.0µin — is a field-service-grade plating: in a connector that sees quarterly mating, the contact interface will hold its resistance for well over a decade.
