Coaxial connectors (also known as RF connectors) are electrical connectors used to connect coaxial cables to electronic devices. They can carry high-frequency signals over long distances. These coaxial cable connectors consist of a central pin surrounded by an insulating sheath and an outer conductive shield, which is structured to align and secure with matching interfaces.

## **What Do Coaxial Connectors Do?**

Coaxial connectors provide a convenient method of connecting RF equipment together to ensure a reliable and efficient signal transmission in various electronic devices and systems.

## **Types of Coaxial Connectors**

There are various types of coaxial connectors available, each with its own unique features and uses in different applications depending on factors such as frequency range, impedance, power handling, and environmental conditions like temperature and humidity. Popular coaxial connector types include:

- **BNC Connectors:** These are commonly used in video and radio applications and are easy to install and remove. BNC coaxial connectors are especially favoured for their durability and the reliable connection they provide, which is critical in settings where equipment may be subject to frequent handling or movement.
- **Micro Connectors:** Designed for high-density applications where space is limited. They are typically smaller and have lower power handling capabilities than standard coaxial power connectors. Micro [coaxial cable connectors](https://hken.rs-online.com/web/content/discovery/ideas-and-advice/coaxial-cable-guide) are often used in mobile devices, wireless communication equipment, and other small electronic devices.
- **SMA Connectors:** Subminiature Version A or SMA connectors are used in high-frequency applications, such as radio, GPS, and wireless networks. SMA connectors are known for their excellent electrical performance, ensuring minimal signal loss up to 18 GHz.
- **N Connectors: **N-type connectors are used in higher-power applications like radio transmission systems. While originally designed for frequencies up to 11 GHz, some enhanced N-type coaxial connectors enable them to perform reliably at frequencies as high as 18 GHz.
- **TNC Connectors:** These are like BNC connectors but are specifically designed for outdoor use. Their threaded coupling mechanism ensures they remain tightly connected, even in harsh environments where they must withstand exposure to moisture, vibration, and temperature fluctuations, making them ideal for reliable performance in rugged applications.
- **F Connectors:** These F-type coaxial power connectors are commonly used in cable TV and satellite systems to conduct an electrical signal. They are known for their reliability and ease of use, making them popular in various RF connector applications.
- **SMB Connectors:** Subminiature Version B, commonly known as SMB connectors, are widely used with industrial electronics and telecommunications equipment. These coaxial connectors are designed with a bayonet-style snap-on mechanism, which ensures a secure fit while allowing for easy and rapid connection or disconnection. SMB connectors maintain a consistent 50-ohm or 75-ohm impedance.

## **Coaxial Connector Applications**

Coaxial connectors are used in several applications, including:

- Laboratory
- Test and measurement
- Telecommunications
- Base stations
- GPSLAN
- Antennas
- Consumer electronics

## **How to Choose the Right Coaxial Connector**

When buying a coaxial connector in Hong Kong, begin by checking your system’s frequency range and impedance to ensure you select a connector that matches your needs. For instance, for high-frequency applications, you might need an RF connector that can handle such demands effectively. A BNC to BNC connector, on the other hand, is advisable for achieving seamless connectivity between similar devices.

Also, consider environmental factors such as temperature fluctuations and moisture, which can affect connector performance. Moreover, it's critical to assess the coaxial connector's power handling and mechanical stability to ensure it can withstand potential vibrations, thus maintaining a reliable and durable connection.

To ensure you choose quality connectors, consider purchasing from [RS HK](https://hken.rs-online.com/web/)’ range, which is renowned for reliability and a broad selection of high-quality products that meet diverse technical needs.
