Coaxial Connectors (RF) are used to connect two coaxial cables together in order to ensure signals travel between them without interference or degradation. The 19S105-500L5 is an example of a specific type of coaxial connector used in the RF industry, known as an SMA connector. This article will discuss the application field and working principle of the 19S105-500L5 SMA connector.

Application Field

The 19S105-500L5 SMA connector is a small, threaded connector that provides a secure, low-loss connection between two coaxial cables in the RF industry. It is most commonly used in applications that require a reliable connection with minimal signal loss. This includes telecommunications and broadcasting networks, as well as radio frequency (RF) signal transmissions for testing and measurements. 19S105-500L5 connectors can also be used in other applications that require a low-loss connection, such as medical imaging, consumer electronics, and satellite communications.

Working Principle

The 19S105-500L5 SMA connector is a threaded, screw-on connector that is designed to fit snugly between two coaxial cables. It uses a center pin surrounded by a full-bore sleeve to provide an air-filled dielectric between the two cables. This design reduces signal loss by eliminating the need for a soldered connection, which can introduce impurities and degrade performance. The connector is threaded on one end, allowing it to be secured tightly and easily to the cables, thereby ensuring a reliable and stable connection. The other end typically features a nut-and-ferrule system, which helps with secure mating between the cables.

In addition to providing an air-filled dielectric, the 19S105-500L5 SMA connector also features an electrical contact that helps to reduce contact resistance and prevent oxidation. This contact is made up of a center pin and a beryllium copper sleeve, which work together to provide a reliable connection. The connector also features an O-ring to aid in sealing the connection and preventing the ingress of moisture and dust that can degrade signal performance.

The 19S105-500L5 SMA connector is designed to provide a reliable, low-loss connection in a wide range of RF applications. Its threaded design helps to ensure connectivity and secure mating between the coaxial cables, while the O-ring and electrical contact help to reduce contact resistance, minimize signal loss, and prevent oxidation. This makes the 19S105-500L5 SMA connector a reliable and durable choice for a variety of applications.
