Isixhumi se-BNC sathuthukiswa ngu-Paul Neill waseBell Labs, kanye neka-Amphenol uqobo, uCarl Concelman, yingakho ethola igama elithi “Bayonet Neill–Concelman(BNC)”.Ekuqaleni yakhelwe ukusetshenziswa kwezempi njengesixhumi esincane esisheshayo somsakazo.Ngokukhwelana okusheshayo, i-75 ohm impedance kanye nokuzinza okufika ku-11 GHz, izixhumi ze-BNC zisetshenziswa kakhulu emakethe yokusakaza kanye nezokuxhumana namuhla.
