TNC M CRIMP for LMR240 Cable

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain electrical continuity in high-vibration environments by replacing the BNC bayonet mount with a secure threaded coupling. This male (plug) variant is specifically optimized for the 6.1mm (0.240″) cable class, providing a precision fit for ultra-low-loss LMR240 cables. It is widely utilized in applications where the signal demands lower attenuation than RG58 can provide, but the mechanical stability of a threaded interface is still required for outdoor or mobile deployments.

This connector utilizes a professional dual-crimp termination system. The outer ferrule creates a 360-degree mechanical bond with the cable’s foil and braid shielding, while the precision-machined center pin is crimped to the internal conductor. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent performance up to 11 GHz. The threaded design provides superior EMI shielding and moisture resistance, making it ideal for base station antennas, GPS distribution, and industrial wireless networking.

Key Technical Advantages

• LMR240 Precision Calibration: Specifically engineered to fit 0.240-inch OD cables, ensuring a seamless mechanical transition and high-strength pull-off resistance for low-loss cable runs.

• Vibration-Proof Threaded Interface: The 7/16-28 threaded mechanism ensures a constant mechanical and electrical connection, preventing signal intermittent issues in high-shock or outdoor applications.

• Low-Loss Signal Integrity: Designed to complement the high-performance characteristics of LMR240, maintaining low VSWR and stable 50-Ohm impedance up to 11 GHz.

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

• Superior Environmental Durability: The nickel-plated brass construction and PTFE dielectric offer excellent resistance to thermal cycling, oxidation, and UV exposure in tower-mounted systems.
