Heat-Shrinkable BNC/TNC Connectors
Heat-Shrinkable BNC/TNC Connectors
Application
The RF One Step series revolutionizes coaxial termination. These single-piece connectors enable simultaneous soldering of the center conductor and braid in a single heating cycle. Fully intermateable with MIL-C-39012 connectors, available in 50-ohm and 75-ohm versions. They offer superior cable retention force, vibration resistance, and signal integrity up to 2.8 GHz. By replacing complex multi-piece assemblies, they significantly reduce installation time and total installed cost.
Series Overview
• Interface: BNC / TNC
• Impedance: 50Ω / 75Ω
• Styles: Straight Plug, Right-Angle Plug, Bulkhead/Panel Jack.
• Sizes: Available in Large, Medium, and Small to accommodate various cable diameters.
Features and Benefits
• Full Solder Connection: Terminates both center conductor and braid with solder for minimal contact resistance and long-term reliability.
• Exceptional Cable Retention: Withstands high vibration and frequent mating/unmating (Retains up to 822N), outperforming standard crimps.
• One-Step Efficiency: Pre-assembled single-piece design simplifies installation, reducing labor time and component loss.
• High-Frequency Performance: Frequency coverage up to 2.8 GHz, compatible with standard RG cables.
• Vibration & Environmental Seal: Adhesive-lined tubing shrinks to provide robust mechanical reinforcement and protection against moisture.
