N M CLAMP for LMR300 Cable

Description

The N-Type connector is a heavy-duty RF interface designed for superior power handling and exceptionally low signal loss at microwave frequencies. This male (plug) variant is specialized for the 7.62mm (0.300″) cable class, specifically optimized for LMR300. Unlike crimp-style connectors, this variant utilizes a mechanical clamp termination system. This design uses an internal compression sleeve and a rear fastening nut to secure the cable’s braid and jacket, providing a high-strength, airtight connection that can be assembled in the field using standard wrenches.

The clamp design is particularly advantageous for custom-length jumper fabrication and maintenance in remote locations, as it eliminates the need for specific LMR300-sized crimp dies. It ensures excellent electrical contact and grounding by applying uniform, high-pressure contact 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, medium-range telecommunications, and industrial RF applications.

Key Technical Advantages

• LMR300 Precision Fit: Specifically calibrated for the 0.300-inch OD cable family, ensuring maximum pull-off resistance and an optimized electrical transition for mid-sized low-loss coaxial lines.

• Field-Serviceable Assembly: The clamp-style design allows for high-integrity installation and reuse without specialized crimping equipment, perfect for on-site repairs and laboratory prototyping.

• 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 cable’s internal 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 the life of the hardware.
