Coaxial Connectors (RF)

The 142-9403-104 (Alpha) is a high performance coaxial connector designed for use in the Radio Frequency (RF) and microwave industries. It is ideal for applications that require minimal loss, a high quality connection and superior signal integrity.

Design Characteristics

The 142-9403-104 coaxial connector is a radial connector with a threaded coupling and male or female gender. It has a full line of adapters, plugs, and receptacles that can be used with various coaxial cables. The contact design features an inner contact which is machined to a unique "Y"-shaped profile with dual points of contact and a four point contact between the outer contact and the barrel connector. This ensures no loss and high signal integrity while providing superior electrical performance and reliability.

Applications

The 142-9403-104 is ideal for a range of applications in the RF and microwave industries including base stations, repeaters, and broadcast transmitters. It is also suitable for use in compact or push-fit applications such as multipin cable assemblies, splitters, and power splitter boxes. Additionally, it can be used in mobile or hand-held radios, military radios, satellite communications, avionics, fiber optics, and any other applications requiring RF interconnection.

Working Principle

The 142-9403-104 coaxial connector is designed to provide optimal electrical performance and achieve a reliable connection to a coaxial cable. It features two contact points—an inner contact and an outer contact—that are designed to make a secure connection and provide electrical isolation.When in operation, the inner contact is inserted into the center conductor of the coaxial cable. As the two contacts come into contact, a four point contact is created between the inner contact, outer contact, and the barrel connector. This ensures that there is no loss and a secure connection is made. The connector\'s mechanical design also ensures that the contacts remain firmly in contact even when subject to vibrations or forces.The 142-9403-104\'s design also ensures that it can be used in a wide variety of applications that require a reliable connection and minimal loss. It is ideal for use in extreme environmental conditions as it is resistant to EMI, vibration, and extreme temperatures. Additionally, it can be used in both push-fit applications and threaded applications, making it ideal for most applications.

Conclusion

The Alpha 142-9403-104 coaxial connector is an ideal solution for applications that require minimal loss, a high quality connection, and superior signal integrity. Its unique design ensures that it can be used in extreme environmental conditions while providing a secure connection. Additionally, it is compatible with a full range of adapters, plugs, and receptacles making it suitable for various coaxial cable applications in the RF and microwave industries.
