Description
The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain electrical continuity in environments subject to high vibration and mechanical shock. This female (jack) variant is specifically optimized for RG59 coaxial cable, providing a precision fit for the standard 0.242-inch outer diameter. It is an ideal solution for cabinet transitions and equipment interfaces that require a secure, threaded connection for analog video, broadcast, or industrial control signals.
This connector utilizes a professional crimp termination system. The outer ferrule provides a 360-degree mechanical bond with the cable’s braid and shielding, while the internal center socket is precision-machined to ensure a low-resistance signal path. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent performance and superior EMI shielding compared to standard bayonet-style (BNC) jacks. The threaded design prevents accidental disconnection, making it a staple for mobile security units, cellular towers, and tactical RF deployments.
Key Technical Advantages
-
RG59 Precision Match: Specifically calibrated for the 0.242-inch OD cable family, ensuring an optimized electrical transition and high-strength pull-off resistance.
-
Vibration-Proof Threaded Interface: The 7/16-28 external threads provide a secure mechanical lock, preventing signal intermittent issues common in mobile or high-shock industrial applications.
-
Rugged 360° Crimp Termination: The precision ferrule provides a permanent, airtight grip on the cable jacket, protecting the dielectric from moisture ingress and mechanical stress.
-
Superior EMI/RFI Shielding: The threaded coupling and solid metal construction offer exceptional shielding, reducing signal interference in high-density cabling environments.
-
Industrial-Grade Build: Features a nickel-plated brass body for corrosion resistance and a gold-plated center contact for consistent signal integrity over thousands of mating cycles.
