Coaxial Connectors (RF)

Coaxial connectors (RF) are used to attach one electronic component to another, allowing transmission of signal and energy. Coaxial connectors are commonly used in communications, measurement, and computing technology. The 127-0711-321 is a type of coaxial connector that is part of the 7/11 series. This particular connector is an RF coaxial connector specifically designed for radio frequency applications; it is an impedance-matched and shielded 4-hole connector.

Application Field

127-0711-321 coaxial connectors (RF) are used in numerous applications, particularly in the commercial radio frequency (RF) industry. Examples of applications for this connector include RF receivers and antennas, two-way radio systems, Bluetooth, digital audio broadcasting, Wi-Fi, vehicle communication systems, and fiber-optic or copper cabling systems.

Working Principle

The working principle of a 127-0711-321 RF coaxial connector is to enable the transmission of a signal between two components while minimizing interference and energy losses. The connector consists of two components; an inner conductor or pin and an outer conductor or terminal contact. The pin is usually made from brass or copper, while the terminal contact is made from gold-plated brass. When the connector is connected, the pin, outer contact, and dielectric form a cylindrical electrical conductor, which shields the outer contact from the inner contact. This signal isolation helps protect the inner contact from external interference and signal losses. The 4-hole connector reduces noise by introducing a further electromagnetic shield, which helps further reduce interference.

The 127-0711-321 is designed to be highly reliable and has a low-insertion-force connection. It features quick-mate options for fast connection and boasts a high temperature rating of up to 175°C for harsh environment applications. In addition, the connector has an impedance of 50 ohms, low signal losses, and fast response time.

Conclusion

The 127-0711-321 RF connector is a reliable coaxial connector designed specifically for radio frequency applications, including two-way radios, digital audio broadcasting, and wireless systems. The connector is designed with a low-insertion-force structure to enable a fast connection process and to minimize interference and signal losses. It features a high temperature rating of up to 175°C, low signal losses, and fast response time, making it suitable for harsh environment applications.
