Sealed 3-Position Power Plug for Wet Environments
The Hirose HR30-6PA-3S(71) is a 3-position (power) plug with female sockets from the HR30 series, designed for applications where water ingress is a real risk. The push-pull fastening type gives a positive lock without threads, and the keyed orientation prevents mis-mating in multi-connector harnesses.
Cable Fit and Termination Reality
The cable opening range is 0.138" to 0.169" (3.50 mm to 4.30 mm), so the cable jacket OD must fall inside that window for the backshell and strain relief to clamp properly. Termination is solder cup — no crimp tool needed, but you'll want a controlled-tip iron and a fixture to hold the contacts steady while soldering. The included backshell and strain relief are molded from PBT, same as the shell, so the whole assembly stays UL94 V-0 rated.
3 vs 6 Positions — When the Circuit Count Decides
Against the 6-position HR30-6PA-6S(71), this 3-position HR30-6PA-3S(71) carries the same 0.138" to 0.169" cable opening, same IP67 rating, same push-pull lock, and same solder cup termination. If your load needs three power circuits at 5 A each, the 3-position shell is the correct choice — the 6-position variant splits its current budget across more contacts and derates to 2 A per circuit.
