Board fit and routing density
The 5-104362-6: The 4-wall shroud with a keying slot protects the square male pins during handling and prevents mis-mating with non-keyed receptacles — a practical safeguard in harness assembly where multiple similar headers share a panel.
Contact interface and mating cycle life
15µin gold over nickel on the mating face supports 500+ mating cycles minimum — in a field-service application cycled quarterly, that is over a century of service life at the contact interface. Tin-plated posts (100µin) handle solder or press-fit termination without corrosion concerns. The latch holder fastening type locks the header to the mating receptacle, resisting vibration-induced disconnect in automotive and industrial environments.
