75 Ohm BNC for Video and Precision RF Paths
The 031-71059: The zinc die-cast body with nickel finish provides RF shielding and environmental protection for the bulkhead mount. Rated to 1 GHz with a 0.2 dB insertion loss, this jack suits composite video, SDI, and baseband RF links where signal integrity matters over a few hundred MHz. The 500 mating cycles mean it holds up in test racks and field-deployed gear that gets reconnected regularly — not a one-and-done install. The shield terminates via solder to the bulkhead or PCB ground plane.
The dual mounting method lets you secure the connector mechanically to the panel before soldering the signal and ground connections — a common practice in chassis-mount RF assemblies. The dielectric is polypropylene, chosen for stable impedance up to 1 GHz. The body includes a board guide feature for alignment during PCB insertion. Housing colour is listed as black and silver.
