Description
The BNC male solder connector is a standard in the RF industry, valued for its quick-connect/disconnect bayonet coupling and reliable mechanical locking. This variant is specialized for the .141-inch cable class, specifically optimized for solid-jacket Semi-Rigid and hand-formable RG402 cables. Unlike standard crimp connectors, this model is designed for high-precision environments where signal phase stability and maximum shielding are paramount.
This connector utilizes a direct-solder termination for both the center conductor and the outer jacket. By soldering the cable’s copper or silver-plated jacket directly into the precision-machined rear bore of the connector body, the assembly achieves an airtight, 360-degree electrical bond. This method provides superior grounding and ensures the lowest possible VSWR at microwave frequencies. Manufactured with a durable nickel or tri-metal plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and exceptional shielding effectiveness up to 4 GHz and beyond.
Key Technical Advantages
-
Direct-Solder Body Interface: The solder-on design creates a continuous metallic shield with the cable jacket, providing maximum EMI/RFI protection essential for sensitive signal paths.
-
Precision .141/RG402 Match: Specifically calibrated for the 0.141-inch OD jacket, ensuring an optimized electrical transition and high mechanical rigidity for specialized cable assemblies.
-
Secure Bayonet Coupling: Features the classic two-stud bayonet locking system for rapid, tool-less mating that remains secure under vibration and movement.
-
Phase-Stable Performance: The permanent solder bond minimizes signal fluctuations and non-linearities, making it ideal for precision jumpers and lab-grade test cables.
