Sealed 6-Position Push-Pull Receptacle for Harsh Environments
The Hirose HR30-6R-6SD(71) is a 6-position (Power) receptacle with female sockets from the HR30 series. The gold-plated mating contacts (8.00 µin) resist corrosion through repeated mate cycles, which matters when the connector is field-serviced.
The termination is solder, meaning you hand-solder or wave-solder the contacts to the board or wire leads. The keyed orientation ensures the plug only mates one way, which eliminates pin damage from a rotated insertion. For a harness builder, the solder-cup termination means you don't need a crimp tool — just strip, tin, and solder each contact into its cup. The shell material is PPS, a high-temperature thermoplastic that handles the soldering heat without distortion.
HR30-6R-6SD(71) vs HR30-6R-6S(71): Solder vs Solder Cup
The closest sibling to this part is the HR30-6R-6S(71). Both are 6-position receptacles with the same IP67 rating, gold plating, and push-pull lock. The difference is termination: the -6SD uses solder contacts (through-hole PCB mount), while the -6S uses solder cup contacts for wire termination. The contact material also differs — the -6SD uses copper alloy, the -6S uses bronze alloy. Pick the -6SD if you're soldering directly to a PCB; pick the -6S if you're terminating individual wires into the connector.
