Description
SMA Plug (Male) to Mini UHF Jack (Female) RF Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1MU25A/911-94 RF adapter features a screw-lock coupling mechanism on both ends, supporting 50 Ω impedance and operating from DC to 2.5 GHz. With ≥500 mating cycles and axial captivation forces of ≥27 N (SMA) and ≥30 N (Mini UHF), it ensures reliable mechanical engagement and low contact resistance. The adapter is rated for temperatures from -55°C to +165°C and withstands up to 1000 V rms test voltage.The SMA side includes beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating, brass body with similar plating, PTFE insulator, silicone rubber gasket, and a brass coupling nut. The Mini UHF side uses beryllium copper contacts, brass body with copper-tin-zinc alloy plating, and PTFE insulation.
