TNC connectors

Overview

TNC connectors (Threaded Neill–Concelman) are RF coaxial connectors using a threaded coupling mechanism to ensure mechanical stability and consistent electrical performance. They are commonly used where vibration resistance and reliable impedance control are required.

Configurations and variants

• Male and female interfaces
• Straight and right-angle versions
• Cable termination and panel-mount types
• PCB mount TNC connectors for RF boards

Technical characteristics

• Impedance typically 50 ohm
• Threaded coupling for secure connection
• Compatible with standard RF coaxial cables
• Designed for RF and microwave signal paths

Applications

• RF test and measurement equipment
• Telecommunication systems
• Industrial RF modules
• Antenna and wireless infrastructure

Frequently Asked Questions

What is the difference between TNC and BNC connectors?

TNC connectors use a threaded coupling instead of a bayonet lock, improving resistance to vibration and accidental disconnection.

Are TNC connectors suitable for outdoor use?

When combined with appropriate sealing and materials, TNC connectors can be used in outdoor RF installations.

Do TNC connectors support high-frequency signals?

TNC connectors are designed for RF and microwave applications, depending on connector quality and cable assembly.

Can TNC connectors be mounted on PCBs?

Yes, specific TNC variants are designed for PCB mounting with controlled impedance.

Are all TNC connectors interchangeable?

Mechanical compatibility is standardized, but electrical performance depends on design, materials and cable matching.

Which cables are commonly used with TNC connectors?

TNC connectors are available for common RF coaxial cables such as RG-series and low-loss industrial cables.
