Description
The TNC (Threaded Neill-Concelman) series is a ruggedized version of the BNC interface, utilizing a threaded coupling to ensure stable electrical contact in high-vibration environments. This Bulkhead (BH) variant is specifically designed to pass through equipment chassis or panels, providing a secure external interface while maintaining an internal cable connection. It is optimized for the 2.5mm to 2.8mm (0.100″ – 0.110″) micro-cable class, offering a precision termination for RG174, high-temperature RG316, and low-loss LMR100.
This connector utilizes a professional crimp termination system and includes a mounting nut and lock washer for a rigid panel attachment. The integrated D-flat (anti-rotation) design ensures the connector remains fixed during the mating process with TNC male plugs. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance up to 6 GHz. Its threaded interface provides superior EMI shielding and environmental resistance, making it an ideal choice for GPS modules, industrial telemetry, and internal wireless equipment wiring.
Key Technical Advantages
-
Secure Bulkhead Integration: Includes a mounting nut and washer for permanent installation through panels or enclosures, creating a professional-grade external antenna port.
-
Anti-Rotation D-Flat Design: The flat-sided body prevents the connector from spinning within the panel hole during installation or when tightening the mated male cable assembly.
-
Micro-Cable Precision Match: Specifically calibrated for 0.100 to 0.110-inch OD cables, ensuring an optimized electrical transition and high-strength pull-off resistance for thin coaxial lines.
-
Vibration-Proof Threaded Interface: The 7/16-28 external threads provide a secure mechanical lock, preventing signal intermittent issues common in mobile, automotive, or aerospace applications.
-
Superior Environmental Durability: The nickel-plated brass construction and PTFE dielectric offer excellent resistance to thermal cycling and oxidation in both indoor and outdoor enclosures.
