TNC Connector

The TNC connector series is a miniature, threaded weatherproof series with a constant 50 Ω impedance and a frequency range of DC to 11 GHz. The TNC series shares its contact design with the BNC series, utilizing a threaded coupling nut for secure mating and higher frequency performance than the BNC. TNC connectors are produced with standard and reverse polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks to ensure quality. Other manufacturers may use reverse threading to accomplish reverse polarity keying. As a result of their versatility and durability, TNC connectors are ideal for a variety applications.

More about TNC Coaxial Connector

TNC (Threaded type) is an upgraded version of BNC. It provides more stable anti-vibration performance through the threaded mechanism and can operate at a maximum frequency of up to 11GHz.

The core difference lies in the connection method: BNC: Snap-on type (Quick plug and unplug) TNC: Threaded type (Stronger vibration resistance) → Applicable scenarios: TNC is a must-have for vibration environments (such as vehicle-mounted and airborne)

The standard TNC is not waterproof, but the TNC-IP67 model (with rubber sealing ring) is optional and can withstand temporary immersion in water (1 meter deep for 30 minutes).

Match according to the demand: Shell: Nickel-plated brass (standard)/Stainless steel (corrosion-resistant) Contacts: Gold-plated (high frequency and low loss)/Silver-plated (low cost) Insulator: PTFE (High-temperature resistant to 260℃)
