Type-N Connectors:  Maximum Corrosion Protection

Composition of Materials:  Weatherproof Plating

• The design of materials is focused on achieving a robust and weather-resistant connection.
  • Body of the Connector: Brass with Nickel Plating: This plating-variant is the most durable against corrosion compared to all other brass alloys with plating (surpassing even gold plating), making it suitable for prolonged exposure outdoors.
  • Standard Nickel-Plated Connectors: Can withstand a salt spray test of 70 hours without showing signs of corrosion.
  • Enhanced Corrosion Resistance for 120 Hours in Salt Spray Test: Customizing the connector is necessary for this level of durability. While there's no charge for the modification, it does lead to a 4-week increase in delivery time and a 20% rise in the cost compared to the standard cable assembly.
• Central Conductor: Beryllium Copper with a Coating of Gold
• Crimp Sleeve: Copper with a Nickel Coating
• Insulating Material: PTFE
• Both N-male and N-female connectors are equipped with a rubber O-ring internally. This ensures a secure, water-resistant connection when paired with an opposite-gender N-type connector that also has a rubber O-ring, achieving an IP-67 rating when used with Data Alliance’s N-female connectors that include a rubber O-ring.

Dimensions & Additional Details of N-Type Connectors

• The internal diameter of the N-male connector is 0.620-inch (1.57 cm), with the N-female having the same measurement.
• The designation of connector gender is not based on external threads but rather on the internal pin, which may seem non-intuitive.
• N-Type connectors are among the largest RF connector varieties and are commonly used on large, especially outdoor, antennas.
• Our N-Type connectors are designed with a threaded coupling mechanism and are compatible with any N-Type connectors that meet the MIL-C-39012 standard, ensuring reliable RF and mechanical performance. They are crucial in systems where such performance is key.
• The N (male) connector features a knurled design to enable improved grip during installation.

N-Type to N-Type Cables:  Male to Male and Extension (Male to Female)

N connector extension cables are coaxial cable assemblies that are terminated with N connectors at both ends. The N connector cables may be:

• Male to male:  See our N-male to N-male cables here
• N-female to N-female
• N-male to N-female:  All of our N-female to N-male cables are in this subcategory (on the page you are on).

N connector cables are routinely used as antenna cables for N connector antennas, or test cables for testing and measurement devices. The power handling and ruggedness of the N connector lend it to a variety of outdoor applications including telecommunications and wireless networking cables for outdoor antennas.

N connectors can be assembled with different kinds of coaxial cable, depending on applications. They are available in a variety of lengths and cable diameters. The best quality N connector cable assemblies use double-shielded, low-loss, coaxial cables that deliver exemplary performance across a wide range of applications.

Best N connector cable assemblies

These N connector cables combine the N connector with high-quality, double-shielded cable that is known for its low attenuation and reliable performance. The N connector cables are available in two diameters in the gender combination of your choice.
