Product Overview
The 10-32 Coaxial Connectors are precision-engineered threaded RF connectors designed for critical applications demanding robust connectivity, high-frequency performance, and environmental resilience. Utilizing the standardized #10-32UNF threaded coupling, these connectors ensure secure mating and superior electrical integrity across a wide frequency range (DC to 10 GHz). Their rugged construction, combined with corrosion-resistant materials, makes them ideal for mission-critical systems subject to vibration, extreme temperatures, or harsh elements.

Material Impact on Performance
Body Materials:
- Brass: Cost-effective, excellent conductivity, suitable for general-purpose applications.
- Stainless Steel (SS316): Superior corrosion resistance (saltwater, chemicals), high strength, ideal for marine or defense systems.
Platings:
- Gold: Enhances conductivity, reduces contact resistance, and provides excellent oxidation resistance.
- Nickel: Cost-effective, improved durability against wear and abrasion; suitable for indoor use.
Dielectric (PTFE):
- Low loss tangent, high thermal stability (-65°C to +200°C), and excellent RF transparency, ensuring consistent impedance and minimizing signal attenuation.
Design Considerations
- Thread Engagement: Ensure ≥3 turns engagement to prevent damage; use torque limits (e.g., 15-20 in-lbs) for reliable mating.
- Material Compatibility: For harsh environments,Prioritize the combination of stainless steel and gold plating.
- Cable Matching: Use 50Ω cables to avoid impedance mismatches and reflections.
Key Advantages
- Threaded Locking: Superior vibration immunity vs. snap-on connectors (e.g., SMB).
- Wide Temp Range: Outperforms standard connectors (-65°C to +165°C).
- Cost-Effectiveness: Better balance of performance vs. cost compared to SMP or 1.85mm connectors.
Conclusion
The 10-32 Coaxial Connector's threaded reliability, broad frequency coverage, and material versatility make it a preferred choice for applications demanding resilience, precision, and long-term durability. Its compatibility with industry standards ensures interoperability, while its robust construction enables performance across diverse and challenging environments.
