### Key Components & Materials
The "RFX" suffix in the part number typically denotes Amphenol's **commercial-grade** line, which provides a cost-effective solution without sacrificing reliability in standard environments.
1. **Outer Body:** Made of machined brass with nickel plating for durability and corrosion resistance.
2. **Center Contact:** Gold-plated to ensure low contact resistance and prevent oxidation over time.
3. **Insulator:** Usually made of **Delrin** or **PTFE**, providing high insulation resistance and maintaining the 50-ohm impedance.
4. **Coupling Mechanism:** Features the classic two-stud bayonet "twist and lock" system for quick mating and unmating.
