Banana and Tip Connectors, are commonly referred to as Jacks, Plugs, or Tips, are electrical connectors used to interconnect components in a wide variety of applications. This article will cover the 21422 application field and working principles.

2mm Jacks and Plugs – 21422 Applications

2mm Jacks and Plugs designed in accordance with the 21422 specification are commonly used in industrial and telecommunications equipment. These connectors are designed to have an anti-rotation feature that prevents accidental disconnection during use. Because of this feature, the 21422 has become a popular choice for applications involving high vibration or frequent handling. For example, these connectors are commonly used in forklifts, robotics, and machining tools.

The 21422 connectors are also popular in the communications industry for applications where low insertion loss is needed. This is due to the low contact resistance of the connectors. This type of connector provides a very reliable connection that is suitable for applications requiring high data rates. The 21422 is commonly used in radio and antenna applications, base stations, data centers, and other similar uses.

2mm Jacks and Plugs – Working Principle

The working principle of a 21422 connector is simple. The plug is inserted into the socket and two contacts make contact. As the plug is inserted into the socket, the contacts move against each other and form a good electrical connection. This type of connection typically requires no soldering or flame treatment.

The contacts of the 21422 pin and socket are normally made of brass or a brass alloy with a gold plating. This is done to ensure conductivity and longevity. In addition, the contacts are designed to not easily corrode over time or be affected by shock and vibration. This ensures a good connection over time.

The 21422 specification also includes a dust cap for protection. This dust cap is attached to a lanyard and can be easily attached to the plug or socket. This helps keep dirt and other debris out of the contact area during installation and use.

Conclusion

The 21422 specification is a popular choice for industrial and telecommunications applications. It is designed for a reliable connection and has features such as an anti-rotation feature and dust cap. This allows the 21422 to be used in high vibration or frequent handling applications. Additionally, its low contact resistance makes it suitable for applications requiring fast data rates.
