TNC F RA CRIMP for LMR240 Cable

Description

The TNC (Threaded Neill-Concelman) series is a threaded version of the BNC interface, designed to provide stable electrical contact in high-vibration environments. This specialized Right Angle (RA) female (jack) variant is optimized for the 6.1mm (0.240″) cable class, providing a precision fit for ultra-low-loss LMR240 cable. By orienting the cable exit at 90 degrees to the mating interface, it allows for clean cable management in shallow enclosures and prevents mechanical stress on the cable’s minimum bend radius.

This connector utilizes a professional crimp termination system. The outer ferrule provides a 360-degree mechanical bond with the cable’s shielding, while the internal center contact is precision-machined to ensure signal integrity across high-frequency bands. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance up to 11 GHz. The threaded female interface ensures a secure, locked connection when mated with TNC male plugs, making it ideal for aerospace, automotive, and outdoor wireless infrastructure.

Key Technical Advantages

• 90° Space-Saving Geometry: Ideal for installations behind equipment panels or inside compact enclosures where a straight connector would be too deep or cause cable kinking.

• LMR240 Precision Match: Specifically calibrated for the dimensions of 0.240-inch OD low-loss cables, ensuring an optimized electrical transition and high-strength pull-off resistance.

• Vibration-Proof Threaded Interface: The 7/16-28 threaded mechanism prevents signal intermittent issues and accidental disconnection, outperforming bayonet-style connectors in high-shock applications.

• Rugged 360° Crimp Termination: The heavy-walled ferrule provides a permanent, airtight grip on the cable jacket, protecting the dielectric from environmental moisture.

• High-Frequency Stability: Engineered to maintain low VSWR and stable impedance up to 11 GHz, supporting modern dual-band Wi-Fi, GPS, and cellular frequencies.
