Coaxial connectors (RF) are specialized electrical connectors designed for high-frequency signal applications such as radio frequency (RF) applications. One of these connectors, the 031-6501, has many distinct advantages when compared to traditional PCB connections. This article will explain the application field and working principle of this coaxial connector.

031-6501 Application Field

The 031-6501 connector is commonly used in military, aerospace and commercial applications. This connector is lightweight and quickly disconnects and reconnects without tools or special fixtures; this makes it an attractive choice for applications where switching out modules is important. Its high frequency performance also makes it ideal for test and measurement systems, antenna systems, wireless networks, broadcast systems, telecommunication systems, instrumentation systems, PCs and laptops, vehicle mounted applications, and medical systems.

031-6501 Working Principle

This connector, designed to suit RG-58 coaxial cable, is a two-piece, crimp style connector divided into three sections: an inner conductor, an insulator and an outer conductor. The contact system consists of a precut area on the inner conductor where the braid is separated. The 031-6501 utilizes a radial compression crimp joint which crimps the braid to the edge of the inner conductor. This provides a more reliable connection compared to a traditional solder joint.

This connector is designed to tolerate the wear and tear of rough and frequent handling. It provides superior repeatability, and stability, reducing tolerance shift after multiple mating cycles. This makes the 031-6501 suitable for use in applications where consistent performance is essential.

Performance

The 031-6501 has excellent signal to noise performance. It exhibits reduced standing wave ratio (VSWR) from 2 GHz up to 18 GHz, making it ideal for applications such as broadcast systems, wireless networks, and antenna systems. It has an insertion loss of only 0.2 dB from 1 MHz up to 10 GHz and an excellent temperature range of +200°C to -30°C. In addition, this connector is compliant with MIL-PRF-39012, allowing it to be used in military applications.

Conclusion

The 031-6501 Coaxial Connector is ideal for high frequency applications such as radio frequency (RF) transmission. It has an easy-to-use radial compression crimp system, which provides a reliable connection, and excels in signal to noise performance. Its light weight and easy installation make it suitable for a variety of applications, from antenna systems to medical systems. The 031-6501 Coaxial Connector is a great choice for any high-end application.
