Banana connectors are single-wire electrical connectors renowned for their distinctive shape and user-friendly design. These connectors, also known as 4mm connectors due to their common size, are indispensable in various electrical applications, from creating and testing circuits to connecting wires to equipment and circuit boards.

Banana connectors feature a spring-loaded metal tip, typically made of materials like gold-plated brass for optimal conductivity, housed within a durable plastic body. The plastic housing is available in a wide range of colours, including red, black, green, and yellow, often used for polarity identification.

RS offers a comprehensive selection of banana connectors, including banana plugs, sockets and banana couplers, catering to diverse electrical needs.

## **What is the purpose of a banana plug?**

Banana plugs provide a reliable and safe way to connect wires to electronic equipment. They offer several advantages over bare wires, including:

- **Reduced Risk of Short Circuits:** The insulated body of the plug prevents accidental contact between conductors.
- **Improved Connection Quality:** The spring-loaded tip ensures a tight, low-resistance connection.
- **Easy Identification:** Banana connectors often come in colour-coded pairs for easy polarity identification.

## **Types of Banana Connector:**

### **Banana plugs**

Banana Plugs are small cylindrical plugs that have a very distinctive bulged prong. This bulge houses a spring that, when inserted into a socket, presses outwards to ensure a solid and secure connection. 

Banana plugs are the alternative to using bare wire when connecting your speakers to your surround receiver, you can connect them without a screwdriver and it gives you high-quality connection. The term banana plug or banana jack refers to the 4mm version whereas the 3mm and 2mm variations are both called “mini-bananas”. Banana plugs and jacks also come in different safety variations. 

### **Banana Sockets **

Banana sockets are the female connectors of banana plugs. A banana connector (commonly banana plug for the male, banana socket or banana jack for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment.

### **Banana couplers**

Banana couplers are handy accessories that allow you to extend the length of existing wires or create custom cable assemblies by joining two banana plugs together. These simple yet effective connectors consist of a cylindrical sleeve with two receptacles for banana plugs. When inserted, the couplers provide a secure and high-performance connection, maintaining signal integrity and ensuring optimal electrical conductivity.

## **Shrouded vs. Unshrouded Banana Plugs**

Banana test plugs are available in two main styles: shrouded and unshrouded. Each type offers specific advantages depending on the application:

- **Unshrouded banana plugs:** These are the most common type, featuring an exposed metal tip for direct connection. They are compact and easy to use, making them suitable for a wide range of applications.
- **Shrouded banana plugs:** These plugs feature a protective plastic cover around the metal tip, preventing accidental contact with live conductors. This added safety feature is particularly important when working with high-voltage circuits. Shrouded banana plugs are available in both fixed and retractable designs, offering flexibility and protection.

The choice between shrouded and unshrouded banana plugs depends on your specific needs and safety considerations

## **Applications of Banana Connectors**

The flexibility and ease of use of banana connectors make them popular in various fields:

- **Audio Equipment:** Connecting speakers, amplifiers, and other audio components.
- **Test and Measurement:** Used in multimeters, oscilloscopes, and other test equipment.
- **Educational Labs:** Providing a safe and easy way for students to connect circuits.
- **Industrial Control Panels:** Connecting wires to power supplies, sensors, and other devices.
