Series BNC RF Coaxial Connector, short for Bayonet Neill-Concelman Connector, is a classic, versatile RF connecting component featuring a convenient bayonet locking mechanism. Compliant with MIL-C-39012, IEC 61169-70 and GB 11315 standards, it balances reliable performance, easy operation and cost-effectiveness, serving as one of the most widely used core interconnection parts in low-to-mid frequency RF systems across industries.
The series boasts excellent electrical performance and strong versatility. It offers dual impedance options of 50Ω and 75Ω: 50Ω for RF communication and test systems, 75Ω for video and broadcast applications. It supports a working frequency range of DC to 4GHz (up to 11GHz for high-end models), with key parameters outstanding: VSWR ≤1.30, contact resistance of inner conductor ≤0.2mΩ and outer conductor ≤2mΩ, insulation resistance ≥5000MΩ, ensuring stable, low-loss signal transmission and strong anti-EMI capability.
Its unique advantage lies in the quarter-turn bayonet locking design, enabling tool-free, quick mating and disconnection while preventing accidental loosening, suitable for frequent plugging scenarios. Manufactured with precision processes, it adopts brass housing (nickel or gold-plated), gold-plated beryllium copper contacts and PTFE insulators, withstanding -55℃ to +165℃ working temperature and 500+ plugging cycles.
Widely applied in video surveillance (CCTV systems), test instruments, broadcast equipment, medical devices, amateur radio and industrial control systems, it is usually paired with RG-58, RG-59 coaxial cables. As a mature, cost-effective solution, it remains a mainstream choice for versatile RF interconnection, supporting stable signal transmission in various commercial and industrial scenarios.
