Coaxial Connectors (RF)

Coaxial connectors (RF) are a type of connection used in a wide range of applications, from radio and broadcast to defense and aerospace. In this article we examine the 901-173 connector, and the principles behind its working.

901-173 Connector Overview

The 901-173 is a type of RF coaxial connector, designed for applications requiring secure and reliable connections between components in RF systems. It is an N-type connector, which is a medium-size radio frequency (RF) connector commonly used in low-power applications. The 901-173 is also waterproof, making it suitable for outdoor applications such as radio antennas and weather sensors.

The 901-173 has a threaded coupling mechanism, making it easier to connect and disconnect than many other coaxial connectors. Its shell is made out of nickel-plated brass, so it is strong and corrosion-resistant. It also features a 0.08 inch (2.0 mm) center pin, which has 80 ohms of characteristic impedance.

901-173 Application Fields

The 901-173 connector can be used in a variety of applications, especially those involving radio and broadcast. Examples include car and outdoor audio systems, car and outdoor antennas, and weather monitoring equipment. The 901-173 is also suitable for use in the aerospace, defense, and medical fields. Its waterproof housing makes it suitable in marine applications, such as for connecting underwater cables or sensors.

901-173 Working Principle

The 901-173 connector is a coaxial connector, which means it relies on the principles of coaxial cable to create a secure and reliable connection between two components. Coaxial connectors use a center conductor known as the inner conductor, which is surrounded by an insulating material known as the dielectric. The dielectric is then surrounded by a conductive outer tube known as the shield, which is connected to ground.

When two components connected by a 901-173 connector are placed in a closed electrical circuit, RF signals travel through the “inner conductor-dielectric-shield” structure, from one component to the other. The outer shield protects the inner conductor and dielectric from outside interference. This allows for a secure and reliable connection, and ensures that the signals sent and received are free from interference or noise.

Conclusion

The 901-173 is a versatile and reliable RF coaxial connector, suitable for a wide range of applications from radio and broadcast, aerospace, defense, medical, and marine. The 901-173 connector relies on the principles of coaxial cable to create a secure and reliable connection between two components, allowing for interference-free signals.
