D-Sub connectors are one of the most versatile and widely used types of electrical connectors available. 443961-2 is a member of this connector family and has unique features and advantages that make it useful in an array of applications. In this article, we will look at what 443961-2 is, the applications for which it is best suited, and the working principle of the connector.

What is 443961-2?

443961-2 is a two-pole, snap-lock style, D-sub connector that is made up of two parts – a housing and a contact. It is rated for a current of 7.5 amp at 250 volts and has a contact resistance of 40 milli-ohms. The housing is made of a thermoplastic polyester material and the contacts are made of brass with tin plating. The connector is incredibly versatile and can be used with cable sizes between 0.3-2.5mm in diameter and strand cross sections of 0.05-0.3mm2.

Applications for 443961-2 D-sub Connector

The 443961-2 D-sub connector is used in a variety of industrial, consumer, and telecommunications applications. It is found in commercial electronics, industrial control systems, data processing systems, telecommunications equipment, and instrumentation systems. It’s also found in non-commercial applications like computers, cameras, and hobby projects. This connector is popular in the broadcast and live entertainment industries due to its high speed data transfer rate.

Working Principle of 443961-2 D-sub Connector

The working principle of a 443961-2 D-sub connector is fairly straight forward. When the connector is mated, the contact in the housing moves into the contact in the insert. This results in a mechanical and electrical connection being established. When the connector is un-mated, the mechanical and electrical connection is broken as the contact in the insert is no longer in contact with the contact in the housing.

The contact resistance of the 443961-2 is 40 milli-ohms, which is relatively low. This is important for applications that require low power consumption or where signal loss due to resistance is a concern. This low contact resistance also ensures that the connector remains reliable and provides consistent performance.

The D-sub connector has a snap-lock style design that makes it quick and easy to deploy and remove. This is important in applications where frequent mated and un-mated connections are required. Additionally, the connector has a splash resistant design and is suitable for use in equipment exposed to harsh environments.

Conclusion

443961-2 is a two-pole, snap-lock style, D-sub connector that is made up of two parts – a housing and a contact. It is rated for a current of 7.5 amp at 250 volts and has a contact resistance of 40 milli-ohms. The 443961-2 is versatile and is used in a variety of industrial, consumer, and telecommunications applications. The working principle of the connector is quite straightforward, and it has several features that make it ideal for use in tough environments. In conclusion, 443961-2 connectors provide reliable performance and are an excellent choice for any application.
