N M RA CLAMP for 1/4″ Feeder Cable

Description

The N-Type connector is the industry standard for high-reliability RF infrastructure, valued for its mechanical robustness and superior power handling. This Right Angle (RA) variant is specialized for the 1/4″ corrugated cable class, which is frequently used for high-performance jumpers where space is limited. The 90-degree elbow configuration is essential for tight-clearance cabinet routing and bulkhead connections, allowing for clean cable management without exceeding the minimum bend radius of the feeder cable.

This connector utilizes a specialized mechanical compression clamp termination designed to grip the solid, annularly corrugated copper outer conductor of 1/4″ cables. This ensures an airtight, low-resistance electrical bond that maintains superior Passive Intermodulation (PIM) performance. The clamp design allows for precision, high-strength terminations on-site using standard wrenches, eliminating the need for specialized hydraulic crimping tools. Manufactured with a reinforced tri-metal or nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 18 GHz.

Key Technical Advantages

• Compact 90° Routing: Reduces the depth required for connections, facilitating high-density cable management in small enclosures and equipment racks.

• 1/4″ Corrugated Cable Match: Specifically engineered for the annular corrugation profile of 1/4″ cables, ensuring maximum surface contact for superior electrical conductivity and mechanical pull-off strength.

• Low-PIM Performance: The precision-machined clamp interface minimizes non-linearities, a critical requirement for modern 5G, LTE, and multi-carrier wireless networks.

• Field-Installable Design: The mechanical compression system allows for high-integrity assembly on-site, facilitating efficient jumper fabrication and system maintenance.

• Rugged Environmental Sealing: Features integrated O-ring gaskets to provide an IP-rated moisture barrier, protecting the cable interface from oxidation and environmental degradation.
