The 031-70526-23: This particular variant is built for 75 Ohm systems — the impedance that distinguishes it from the more common 50 Ohm BNC — making it the correct choice for video, CCTV, and broadcast signal paths where 75 Ohm is the standard. Rated to 12 GHz, this jack handles high-frequency video and data signals well beyond the typical baseband video range. The nickel-plated brass body provides the standard BNC shielding and environmental durability.
Mounting and Termination Detail
This jack supports two mounting styles: board-edge end launch, where the connector sits at the edge of the PCB and the signal pin is soldered directly to a trace, and panel mount, where the bulkhead nut clamps the connector to a chassis or enclosure panel. The shield termination is solder-type, meaning the outer braid of the coaxial cable is soldered to the body for a continuous ground path. The contact termination is also solder, requiring the center conductor to be soldered to the beryllium copper pin.
