Product Overview
The model of type N female connector is N-K7/8.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.






External Dimensions
Threaded Interface: Threaded interface connection.
External Diameter: Typically between 11mm and 22mm, depending on the model and size series.
Length: Depends on the specific model and design requirements, typically between 30mm and 70mm.
Internal Dimensions
Internal Lead Diameter: Typically between 1.9mm and 5.3mm, with slight variations between models.
Threaded Interface Aperture: The internal aperture of the threaded interface typically ranges from 9mm to 18mm, depending on the model and size.
