Coaxial Connectors (RF)

Coaxial connectors are specialized RF connection devices used to establish and maintain one or more radio frequency circuits, and they are designed to minimize the insertion loss of a radio frequency signal. The 1221-4004 series of coaxial connectors are designed for applications in indoor (non-outdoor) environments, and they are suitable for point-of-sale (POS) terminals, Wi-Fi routers, and satellite receivers. Furthermore, these connectors are resistant to corrosion, dust, and moisture. Understanding the working principle of the coaxial connectors as well as their application areas can be helpful in selecting the right connector for the right situation.

Working Principle of 1221-4004 Coaxial Connectors

The 1221-4004 series of coaxial connectors feature a threaded coupling nut design and a 1/4 inch diameter interface. The central contact pin and the inner insulator are made of brass, while the outer conductor is made of stainless steel. The outer conductor is further housed within a polyamide body and sealed together with an O-ring. The female connector is also installed with a spring-loaded PTFE center contact for a reliable and repeatable connection.

The main objective of the 1221-4004 series of coaxial connectors is to minimize the radio frequency (RF) signal loss between two connecting cables. This is done by optimizing the contact pressure generated between the two interfacing electrical components. This contact force provides a secure connection and superior electrical connection. Furthermore, the threaded coupling nut design allows for quick and easy installation.

Application Areas

The 1221-4004 series of coaxial connectors are designed for indoor (non-outdoor) applications, and thus they are suitable for point-of-sale (POS) terminals, Wi-Fi routers, and satellite TV receivers. This series of connectors is resistant to corrosion, dust, and moisture, which makes them reliable in harsh environmental conditions. Furthermore, the small size and attractive design of these connectors make them suitable for use in confined spaces.

Conclusion

The 1221-4004 series of coaxial connectors are designed for indoor applications, and they provide reliable, repeatable connections between multiple RF circuits. Their optimized contact pressure mechanism provides a secure connection and superior electrical connection. Furthermore, these connectors are resistant to corrosion, dust, and moisture, which makes them reliable for use in harsh conditions. Understanding the working principle and applications areas of the 1221-4004 series of coaxial connectors can be helpful in selecting the right connector for the right situation.
