Coaxial Connectors (RF)

Coaxial connectors, or RF connectors, are widely used in many applications and involve both electrical and electromagnetic aspects. The VN50-2031 is one such component that can be used for various applications and installations. This article provides a brief overview of the VN50-2031, its applications, and its working principle.

Overview

The VN50-2031 is a miniature SMA/SMA cable assembly with a straight body and fully molded connectors. It features a robust stainless steel coupling nut and a nickel-plated brass body. It has an operating temperature range of -55 to +105°C, voltage rating of 1.5kV DC, and excellent electrical and mating characteristics. The host connector features an impressive 70% shrink fit surrounding the dielectric and a precisely machined center contact.

Applications

The VN50-2031 is suitable for numerous application scenarios. Its small form factor and moulded body makes it ideal for use in space-limited environments, such as in-cabinet applications. It also represents a cost-effective solution for prototyping and applications requiring low-frequency RF systems. In addition, its low-profile form factor and relatively low price point make it a great choice for use in test and measurement systems, optical communications, CATV networks, and wireless communication devices.

Working Principle

The VN50-2031 operates in an impedance-matched environment, in which the transmission of the electromagnetic field is conducted through the solid surfaces of the connector. The electrical energy is transferred from the center contact of the host connector to the center contact of the other connector, while the magnetic field travels through the outer surfaces of both connectors.

To maintain the impedance balance, the VN50-2031 features a stainless steel coupling nut that clamps the connectors together as they mate. This coupling nut enables the connectors to form a solid electrical connection and creates a mechanical seal between the two connectors to guarantee the transmission of RF signals without any loss or reflection. The stainless steel coupling nut ensures that the electrical connection is stable and reliable over time.

In addition, the VN50-2031 offers excellent contact performance even in extreme temperature and environmental conditions due to its high-quality dielectric and brass construction. This ensures that the connector is highly reliable and provides a durable performance in harsh conditions.

Conclusion

The VN50-2031 is a versatile and reliable miniature SMA/SMA cable assembly designed for use in various applications and installations. It features a robust stainless steel coupling nut and a nickel-plated brass body, ensuring a stable connection even in extreme temperature and environmental conditions. Its miniature form factor and low price point make it a great choice for use in test and measurement systems, optical communications, CATV networks, and wireless communication devices.
