Coaxial Connectors (RF)

Coaxial connectors (RF) are electrical connectors used to suit for connecting coaxial cables. The 135-9711-802 is a type of low-frequency coaxial connectors. When converting and transmitting signals (low frequency may be in audio or video frequency band), it is necessary to use this classic connector and the related cables.

Application Field

The 135-9711-802 is mainly used in radio frequency (RF), and has a wide application purpose, including the connection of car audio such as car head units, home audio systems, and mobile phones, also, it is commonly used to connect coaxial cables into antennas. The 135-9711-802 is also widely used in military equipments, medical equipments, audio equipments, television, computer, communication equipments, aviation and marine. It meets the requirements of typical low-frequency signals applications.

Working Principle

The 135-9711-802 function mainly depends on the matching of the inner conductor and the outer conductor, and the reliable connection between the cables and connectors. Its working principle is to use the wire and shield as the conductor, and relies on the form of the connector-connector mating and contact to achieve the transmission and conversion of the low-frequency signals. The connectors consist of four major components, the inner conductor, the outer conductor, the insulator and the water resistance part. The inner conductor is composed of a central core, a jacket, a grounding sleeve and a sealing part, and the outer conductor is a conductive shell, which is used to connect the outer conductor of the cable.

The inner conductor acts as an electrical conductor and connect the center pin on the socket. The outer conductor acts as a shielding layer and it can reduce the radiation of signal and reduce the cross-interference between the signal or between the environment. The insulation isolates the inner and outer conductors, prevents the signal from interfering or leaking, and reduces the signal loss caused by metal shielding. The waterproof part can prevent external corrosion and reduce the influence of water infiltration to the signal.

Conclusion

Due to the advantages of low attenuation, good shielding, and environmental resistance, the 135-9711-802 has become a widely used low-frequency signal transmission connector, it is especially suitable for applications that require a good performance in maintaining the signal integrity (SI) and signal quality (SQ). Thus, it can be concluded that the 135-9711-802 is a reliable and versatile connector to suit for all low-frequency signals transmission and application.
