The right-angle body lets the cable exit perpendicular to the adapter axis, useful where a straight adapter would force a bend radius violation or crowd adjacent ports. A 50 Ohm adapter inserted into a 50 Ohm line keeps the characteristic impedance continuous. The 4 GHz max frequency covers cellular, Wi-Fi, broadcast TV, and instrumentation signals. ## Mechanical Construction and Mating Cycle Life The body is machined brass with a nickel finish — nickel provides good corrosion resistance and a consistent surface for the bayonet-lock coupling nut to engage. The center contacts are gold-plated: the male pin is beryllium copper (spring temper for repeated mating), the female socket is brass.","metaTitle":"Amphenol RF 31-9-RFX BNC to BNC Right Angle Adapter, 50 Ohm","metaDescription":"Amphenol RF 31-9-RFX BNC to BNC right angle adapter, 50 Ohm impedance, 4 GHz max frequency.
