The 132170-10RP-RP is an SMA reverse polarity bulkhead jack-to-jack adapter designed for RF and microwave applications requiring secure panel-mount connectivity. The adapter features a brass body with gold plating, a teflon insulator, and a gold-plated brass contact pin, ensuring excellent electrical conductivity and corrosion resistance. The assembly includes a silicon gasket, lock washer, and hex nut (all brass with gold finish) for reliable mechanical retention and environmental sealing. With thread specifications of 1/4-36UNS-2A and 5/16-32UNEF-2A, and dimensional tolerances of ±0.20 mm for 0.5–8 mm ranges, this adapter provides precision engineering for demanding RF interconnect applications. The reverse polarity configuration prevents accidental mating with standard SMA connectors, making it ideal for specialized communication systems, test equipment, and military/aerospace applications where connector integrity is critical.
