Coaxial Connectors 101: All You Need to Know About Different Types of Coax Connectors

Coaxial connectors are commonly used in electronic and telecommunications applications to provide a secure and reliable connection for coaxial cables. Here are some types of coaxial connectors:

1. BNC Connector

The BNC (Bayonet Neill-Concelman) connector is a widely used coaxial connector known for its quick-connect/disconnect mechanism. It features a bayonet-style coupling mechanism that allows for a secure connection with a simple twist. BNC connectors are commonly used in video, audio, and data applications.

2. SMA Connector

The SMA (SubMiniature version A) connector is a popular coaxial connector primarily used in high-frequency applications, such as RF (Radio Frequency) and microwave communication systems. It features a threaded coupling mechanism that provides a secure and stable connection. SMA connectors are commonly used in wireless devices, antennas, and test equipment.

3. N Connector

The N connector is a robust and versatile coaxial connector commonly used in applications requiring high power and low signal loss. It has a threaded coupling mechanism that ensures a reliable and stable connection. N connectors are widely used in RF and microwave systems, including antennas, base stations, and test equipment.

4. F Connector

The F connector is a commonly used coaxial connector for cable television (CATV) and satellite TV connections. It features a screw-on coupling mechanism that provides a secure connection for coaxial cables. F connectors are commonly found on TV antennas, set-top boxes, and cable/satellite receivers.

5. RCA Connector

The RCA (Radio Corporation of America) connector, also known as the phono connector, is a widely used coaxial connector for audio and video applications. It features a circular metal plug with a center pin surrounded by a metal collar. RCA connectors are commonly used in consumer electronics, such as home theater systems, TVs, and audio/video devices.

6. SMB Connector

The SMB (SubMiniature version B) connector is a smaller variant of the SMA connector. It features a snap-on coupling mechanism, making it easy to connect and disconnect. SMB connectors are commonly used in applications that require a compact and lightweight design, such as communication systems and automotive electronics.

These are just a few examples of coaxial connectors commonly used in various applications. The choice of coaxial connector depends on factors such as frequency range, power requirements, and specific application needs.
