As a professional manufacturer of RF connectors, we are committed to providing global customers with high-quality signal transmission solutions. Below is the standardized technical specification for our Connector Model N-J5:
Product Introduction
The Connector Model N-J5 is a threaded coupling coaxial connector specifically designed for high-power RF systems. The "J" designates the male (pin) structure, and the "5" indicates its compatibility with specific standard coaxial cables. Featuring a threaded coupling mechanism, this connector offers exceptional mating security, outstanding vibration resistance, and high-voltage/high-power handling capabilities. Backed by over 30 years of precision manufacturing experience and a rigorous quality control system, we ensure that every N-J5 connector maintains an extremely low VSWR and stable signal transmission even in harsh environments.
Working Principle
This connector operates based on the coaxial transmission line principle. Electrically, the internal center pin makes precision contact with the center receptacle of the mating female connector, ensuring low-loss RF signal transmission. The outer metal shells mate tightly via threads to form a complete outer conductor circuit, providing 360° electromagnetic shielding to effectively suppress Electromagnetic Interference (EMI) and signal leakage. Mechanically, rotating the outer threaded coupling nut engages the internal and external threads, achieving a high-strength, anti-vibration physical lock.
Product Structure
The Connector Model N-J5 mainly consists of the following core components:
Outer Conductor (Body): Manufactured from high-quality brass with nickel plating, providing mechanical support, corrosion resistance, and electromagnetic shielding.
Inner Conductor (Pin): Made of high-conductivity copper and plated with silver or gold to minimize contact resistance and enhance high-frequency and high-power signal transmission efficiency.
Dielectric Insulator: Positioned between the inner and outer conductors, utilizing Polytetrafluoroethylene (PTFE) to support the inner conductor, maintain constant characteristic impedance, and provide electrical insulation.
Threaded Locking Mechanism: Includes a precision-machined threaded coupling nut, serving as the critical mechanical structure for highly reliable connection and anti-vibration performance.

Radar & Navigation Systems: Applied in military and civilian radar systems and aviation navigation equipment for high-frequency signal transmission.
Test & Measurement Instruments: Serving as standard RF interfaces for network analyzers, high-power signal generators, and other precision equipment.
Industrial & Medical Equipment: Utilized in industrial RF heating systems and medical Magnetic Resonance Imaging (MRI) equipment requiring high-power RF transmission.
Usage Precautions
To ensure the optimal performance and service life of the Connector Model N-J5, please observe the following precautions during installation and operation:
Proper Mating/Unmating: Always grip the threaded coupling nut to rotate and lock/unlock. Never pull directly on the cable or forcefully twist the connector body to avoid damaging the internal structure.
Torque Control: Always use a dedicated torque wrench when tightening the threads. Strictly follow our provided torque specifications to prevent thread stripping or deformation caused by excessive force.
Interface Cleaning: Inspect and clean the pin and insulator mating faces before connection. Prevent dust, metal shavings, or other foreign objects from causing poor contact or short circuits.
Cable Compatibility: For cable-end termination products, strictly follow our provided stripping dimensions and termination processes to ensure reliable connections for both inner and outer conductors.
Packaging & Lead Time
Packaging: Standard packaging includes individual anti-static bags, packed in high-strength corrugated cartons with cushioning materials to protect the connectors from compression and moisture during long-distance sea or air freight. Customized pallet packaging is also available upon request.
Lead Time: For standard Connector Model N-J5 products, we typically maintain ample inventory, allowing for shipment within 1-3 working days after order confirmation. For special specifications or bulk custom orders, the standard production cycle is approximately 15 working days. The exact lead time will be confirmed upon order placement.
