Sealed 6-Position Power Receptacle for Wet Environments
The Hirose HR30-6R-6S(71) is a 6-position (power) female receptacle from the HR30 series, designed as a panel-mount, bulkhead-sealed circular connector. It carries an IP67/IP68 rating — dust-tight and submersible — making it a fit for applications where washdown, rain, or condensation would kill an unsealed connector. The 6 circuits are rated 2 A per contact at 100VAC or 140VDC, which puts this in the signal-and-small-actuator power range: sensor feeds, marine electronics, medical device I/O, and industrial control panels where a 2 A circuit is enough and the environment demands a seal.
IP67/IP68 — What the Rating Means for Installation
The IP67/IP68 rating is the headline feature here. IP67 means the mated pair survives immersion to 1 meter for 30 minutes; IP68 extends that to deeper, longer submersion per the manufacturer's test conditions. For a panel-mount receptacle, the seal depends on the O-ring between the bulkhead and the panel face — the rear-side nut compresses that seal. In a marine or washdown cabinet, that saves time during service, but the seal integrity relies on the panel cutout being clean and the nut torqued correctly — the connector itself is rated, but the installation determines whether it actually seals.
Termination: Solder Cup — Field or Bench
Termination is solder cup, not crimp. That means each of the 6 female sockets gets a wire tinned and soldered into the cup. Solder cup is common in marine and medical harnesses where a technician builds the cable to length on-site. No special crimp tool needed, but the soldering must be clean — a cold joint or stray flux inside the cup can compromise the 2 A rating. The bronze alloy contact material is standard for this class; the gold flash prevents corrosion at the mating interface.
The mating plug for this receptacle is the Hirose HR30-6R-6P(71) — a 6-position male pin version with the same shell size (6) and solder cup termination. Both parts share the IP67/IP68 rating when mated. The panel cutout for the bulkhead mount is a standard circular hole sized for the HR30 shell; the rear-side nut clamps from behind the panel. No thread coupling — push-pull fastening locks with a positive detent. For a 6-circuit power interconnect in a sealed enclosure, this pair is a direct fit.
