TNC M CRIMP for LMR400/RG8/RG11/RG213/RG393 Cable

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain electrical continuity in high-vibration and high-shock environments. This male (plug) variant is specialized for the 10mm (0.400″) heavy-duty cable class, providing a precision termination for ultra-low-loss LMR400, military-spec RG213, and high-temperature RG393. It is the essential connector for applications that demand high power handling and low attenuation over long cable runs, where a standard BNC would fail to provide the necessary mechanical security.

This connector utilizes a professional heavy-duty crimp termination system. The oversized outer ferrule creates a 360-degree mechanical bond with the cable’s braid and shielding, while the precision-machined center pin is typically crimped to the internal conductor. Manufactured with a reinforced nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent performance up to 11 GHz. The threaded interface provides superior EMI shielding and environmental resistance, making it ideal for cellular towers, maritime communications, and tactical RF deployments.

Key Technical Advantages

• Large-Diameter Precision Match: Specifically calibrated for the 0.400-inch OD cable family, ensuring a seamless mechanical transition and high-strength pull-off resistance for heavy-gauge coaxial lines.

• Vibration-Proof Threaded Interface: The 7/16-28 threaded mechanism ensures a secure, locked connection, preventing signal intermittent issues in high-G aerospace or industrial mobile applications.

• High-Power Handling: Designed to support the increased power throughput of RG8 and LMR400 cables, maintaining low VSWR and stable 50-Ohm impedance.

• 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.
