Shield termination is crimp, contact termination is crimp. This means Amphenol RF is no longer actively promoting this part for new projects, though it remains available for existing production runs and field replacements. For a new BOM line, a parametric search on 75 Ohm BNC plugs with crimp termination and 4 GHz bandwidth will identify the current-generation equivalent. ## Cable Compatibility and Field Termination This plug is specified for Belden 1694, 1694A, and 9248 cables — all 75 Ohm precision video coax types with solid or foam polyethylene dielectric. The crimp ferrule and center contact are sized for these cable diameters. The 500 mating cycle rating, supported by the gold-plated center contact, means this connector holds up to repeated patching in a studio or head-end rack without signal degradation from contact wear.","metaTitle":"Amphenol RF 031-80109 BNC Plug, 75 Ohm, 4 GHz, NRND","metaDescription":"Amphenol RF 031-80109 BNC plug, 75 Ohm, 4 GHz max, 500 mating cycles.
