142-4404-001 Connectors, Interconnects

Coaxial Connectors (RF)

Coaxial connectors are connectors designed to work in radio frequency (RF) systems. They are commonly used in cable assemblies for communications and broadcasting systems, test and measurement, and audio/video applications that transmit signals by shielded coaxial cables. A variation of the RF antenna connector is the 142-4404-001, which is a subminiature variant.

Application Field of 142-4404-001

With a small form factor and good electrical performance, the 142-4404-001 is designed to be used in high-density RF equipment with limited space, such as radio equipment, hand-held radios, two-way radios, and meter reading. It is also often used for long distance wireless applications. It is available with 0.050" (1.27mm) and 0.086" (2.18mm) pin thickness while offering the choice of solder or crimp termination to meet the application requirements of different systems.

Working Principle of 142-4404-001

The 142-4404-001 works by using a center conductor or pin surrounded by an insulating dielectric material and a grounded outer conductor. The two conductors are separated by an insulating spacer for mechanical support. The electrical connection between these two conductors is formed by the contact between the conductor and the center pin or outer conductor when the connector is coupled. The contact force also provides RF shielding.

When the connector is inserted into its mating connector, the outer conductor mates with the outer portion of the mating connector at the sheath interface, while the center pin or outer conductor mates with the center pin of the mating connector, forming an electrical connection. It is important to ensure that the mating surfaces of the connector are clean and smooth to prevent the occurrence of physical interruptions. A good contact should be achieved in order to obtain a reliable electrical connection.

Conclusion

The 142-4404-001 is a versatile coaxial connector designed for use in high-density RF equipment with limited space. Its small form factor makes it suitable for many applications such as radio equipment, hand-held radios, two-way radios and meter-reading. It works by creating electrical connections between its conductor and the mating connector when they are mated together, providing excellent electrical performance as well as RF shielding.
