Description
The TNC (Threaded Neill-Concelman) series is a high-reliability version of the BNC interface, utilizing a 7/16-28 threaded coupling to maintain electrical continuity in high-vibration and high-shock environments. This female (jack) variant is specialized for the 2.5mm to 2.8mm (0.100″ – 0.110″) micro-cable class, providing a precision fit for versatile cables such as standard RG174, high-temperature RG316, and low-loss LMR100. It is an ideal solution for compact device enclosures and antenna feeds that require a threaded, vibration-proof connection in a small form factor.
This connector utilizes a professional crimp termination system. The precision-machined outer ferrule provides a 360-degree mechanical bond with the cable’s shielding, while the internal center socket is typically soldered to ensure maximum signal integrity on small-gauge conductors. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 6 GHz (usable up to 11 GHz). The threaded interface ensures a reliable connection when mated with TNC male plugs, making it a staple for telecommunications, medical electronics, and industrial telemetry.
