Overview
The Rosenberger BNC coaxial connector is a compact bayonet-style RF connector engineered for reliable high-frequency signal transmission in demanding laboratory, telecom, and data system environments. Available in 50 Ω and 75 Ω impedance options, this connector delivers consistent performance across DC–4 GHz frequency range with minimal return loss and secure mechanical coupling via its distinctive two-stud bayonet locking mechanism.
Key Features
- Two-stud bayonet locking mechanism for quick quarter-turn connection and disconnection
- 50 Ω or 75 Ω impedance variants to match your cable and system requirements
- Frequency range: DC to 4 GHz for broad RF application coverage
- Return loss ≥ 20 dB (typical) ensures excellent signal integrity
- Brass body with nickel plating for corrosion resistance and durability
- PTFE dielectric insulation for stable electrical performance across temperature extremes
Technical Specifications
Rosenberger BNC connectors conform to industry-standard IEC 60169-8 specification, ensuring interoperability with equipment from major RF and test instrument manufacturers. The connector body is constructed from brass with nickel plating, while the center conductor is typically gold-plated for enhanced contact reliability. PTFE (polytetrafluoroethylene) insulation maintains consistent impedance and operating performance from –55 °C to +155 °C.
