The white bronze body finish on the brass shell provides corrosion resistance without the galvanic mismatch risk of nickel on stainless in outdoor enclosures. ## Cable Termination and Field Fit This hybrid termination is standard for semi-rigid and flexible coax up to 0.100-inch diameter — the listed cable group covers RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174. The beryllium copper center contact with gold plating handles the 100-cycle mating life without fretting corrosion at the interface. Mounting is bulkhead front-side nut: the jack passes through a panel hole, the lockwasher seats against the panel face, and the hex nut tightens from the outside. The PTFE dielectric maintains consistent impedance through the transition from cable to connector body.","metaTitle":"Amphenol RF 930-124J-51S QMA Jack, 50 Ohm, 11 GHz, RG-174","metaDescription":"Amphenol RF 930-124J-51S QMA jack, female socket, 50 Ohm, DC-11 GHz, snap-on mating.
