Product Overview
The model of N male crimp type connector is N-J7.N series are very popular screw-coupling middle-or-low power coaxial connectors with impedances of 50Ω and 75Ω. They are widely used for electrical instruments or applications where vibration resistance and environmental protection is required, including communication equipment, coaxial components,duplexers, couplers, microwave testing system and microwave network or connecting RF cables. Connected with high accuracy semi-flexible or semi-rigid cables N connectors can work up to11GHz resulting in low VSWR.

FAQ
Q: What to do to ensure the electrical performance of N-type connector?
A: 1. Materials. This is something I've always emphasized. Start with the source of production. If even the foundation of a skyscraper is a bubble project, how can you dream of building one? High-quality materials are the key.
2. Plating. To achieve stable impedance, the connector surface metal contact interface needs to provide inherent stability. The surface film needs to be able to avoid or separate during mating. The choice of plating material and the quality of the plating process have a significant impact on electrical performance.
3. Design. Adding insulation around the terminals, as well as design factors such as the shape, height, spacing, withstand voltage, and electrical clearance, all affect electrical performance. A design plan should be prepared early on based on the product's electrical performance requirements.
4. Inspection. This is an essential step for any product that is shipped. No matter how impressive you claim to be or how experienced you are, this step is essential. A connector manufacturer's rigorous inspection process is essential. This is not only a responsibility to customers to ensure the safe use of their products, but also a fundamental obligation. It is also a key line of defense to prevent inferior products from entering the market.
