The 000-46650-93RFX: Its 93 Ohm impedance sets it apart from the common 50 Ohm or 75 Ohm BNC variants — this is a niche value used in certain video distribution, data acquisition, and legacy broadcast systems where the line impedance is specified at 93 Ohms. The nickel-plated brass body and gold-plated contact give it good corrosion resistance and reliable signal transfer over repeated mating cycles. The dielectric is polyoxymethylene (POM) acetal, a stable insulator for RF applications.
93 Ohm Impedance — Why That Matters
Most BNC connectors are 50 Ohm (RF/microwave) or 75 Ohm (video/CCTV). The 93 Ohm value here is for systems that specify that exact impedance — typically older IBM 3270 coaxial terminals, some industrial video links, or specialized data networks. If your system calls for 93 Ohm, this plug is a direct match. If you need a standard 75 Ohm video BNC, the sibling 000-46650-75RFX is the right pick; for 50 Ohm RF work, the 000-46650-51RFX covers that. Mixing impedances causes reflections and signal loss, so match the line impedance exactly.
