What is a TNC RF Connector?

Many TNC plugs can be assembled by replacing the coupling with a BNC 50Ω plug. Since assembly can be done in about 1W after receiving an order, there are cases where a BNC50Ω plug can be assembled if available, even if it is not available in TNC's regular products.

Some TNC connectors are stamped with BNC because they are made from the same materials as BNC connectors.

We have connectors with a crimp-type cable attachment. Although a crimping tool is required for the assembly, it is lighter and less expensive than the clamping type connectors. You do not need to purchase crimping tools if you request us to process the cable assembly.

TNC connectors are widely used in telecommunications, military, industrial, and test applications. They excel in radio communication equipment, GPS systems, test instruments, and antenna connections, delivering reliable RF performance under vibration or harsh conditions.

TNC connectors feature a threaded coupling mechanism, offering superior resistance to shock and vibration compared to bayonet-style BNC connectors. They're smaller than N-type connectors while maintaining similar reliability, making them ideal for space-constrained, rugged environments. With standard 50 Ω impedance (and 75 Ω options), they ensure versatile, high-performance RF connectivity.

TNC (Threaded Neill-Concelman) connectors use a threaded coupling for enhanced durability in high-vibration settings, while BNC (Bayonet Neill-Concelman) connectors rely on a quicker bayonet-style connection suited for less demanding environments. TNC connectors provide superior RF stability.

TNC connectors are more compact than N-type connectors but share the same threaded reliability. TNC is preferred for space-saving durability.

TNC connectors are primarily 50 Ω for RF and microwave applications, with 75 Ω versions available for video and broadcast uses. While 50 Ω connectors can work with 75 Ω cables up to 200 MHz with minimal loss, matching impedance is recommended for optimal signal integrity.

Standard TNC connectors have a female contact in the jack and a male contact in the plug. RP-TNC connectors reverse this (male in jack, female in plug) to prevent mating with standard connectors commonly used in Wi-Fi and wireless networking.

Tyclon uses brass or stainless steel for durability and corrosion resistance, gold-plated center contacts for conductivity, and PTFE (Teflon) dielectric for low signal loss. Some TNC connectors may be adapted from BNC materials, occasionally bearing a "BNC" stamp.

Due to differing threads and sizes, TNC connectors aren't directly compatible with SMA or N-type connectors, but Tyclon offers adapters for seamless interconnectivity.

Align the male and female threads, twist until finger-tight, and use a torque wrench (1.0-1.2 N·m or 9-11 in·lbs) for a secure fit without over-tightening. This ensures optimal performance and prevents damage.

The threaded coupling provides excellent resistance to vibration, making them a top choice for military, aerospace, and automotive applications.
