The Hirose SR30-10R-6S(71) is a 6-position circular receptacle from the SR30 series, shell size 10, designed for panel-mount radio equipment. It accepts female sockets terminated via solder cup — a field-service-friendly termination that lets you re-pin a harness on site with a basic iron. The threaded coupling nut and keyed orientation prevent cross-threading and mis-mating, which matters when you're swapping a connector in a rack without line of sight to the bulkhead.
The operating range of -10°C to 60°C limits this to indoor or sheltered outdoor enclosures — it won't hold up in an unheated cabinet through a northern winter or in a sun-baked telecom shelter. The chrome-plated brass shell and polyacetal insert are standard for the series, but the narrow temperature window is the real constraint for deployment.
