N M CLAMP for LMR240 Cable

Description

The N-Type connector is a heavy-duty RF interface designed for superior power handling and low-loss signal transmission at microwave frequencies. This male (plug) variant is specialized for the 6.1mm (0.240″) cable class, specifically optimized for high-performance LMR240. Unlike crimp-style connectors, this variant utilizes a mechanical clamp termination system. This design uses an internal compression sleeve and a rear nut to secure the cable braid, providing a high-strength, airtight connection that can be assembled in the field using standard wrenches.

The clamp design is particularly advantageous for maintenance and repair in remote locations, as it eliminates the need for specialized hydraulic or ratcheting crimp tools. It ensures excellent electrical contact and grounding by applying uniform pressure across the cable’s outer conductor. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 11 GHz. The 5/8-24 threaded interface provides superior mechanical stability and environmental resistance, making it ideal for outdoor wireless infrastructure, base stations, and marine RF applications.

Key Technical Advantages

• LMR240 Precision Fit: Specifically calibrated for the 0.240-inch OD cable family, ensuring maximum pull-off resistance and an optimized electrical transition for low-loss coaxial lines.

• Field-Serviceable Assembly: The clamp-style design allows for easy installation and reuse without specialized crimping equipment, making it ideal for on-site tower repairs and field testing.

• Vibration-Proof Threaded Interface: The 5/8-24 threaded coupling provides a secure, locked connection that maintains electrical integrity in high-vibration industrial or mobile environments.

• Rugged Environmental Sealing: Integrated gaskets and a compression-fit rear nut provide an effective moisture barrier, protecting the internal cable dielectric from oxidation and weather-related wear.

• Industrial-Grade Build: Features a nickel-plated brass body for maximum corrosion resistance and a gold-plated center contact for consistent signal clarity over long-term deployments.
