D-sub connectors, commonly referred to as DSUBs, are a type of electrical connector used for applications requiring a robust, reliable connection. The 213045-1 is one specific model in the D-sub family, offering the ability to connect up to twenty-one contacts in an array. Its specialized design allows for easy connectivity, and its low cost makes it an attractive option for budget-conscious projects. In this article, we’ll explore the application field and working principle of 213045-1 D-sub connectors.

Application Field"

213045-1 D-sub connectors are suitable for a wide range of applications, including industrial automation, data communication, and test and measurement. Their robust contact system makes them ideal for an environment with frequent vibration and shock, and their low cost and relative simplicity make them a popular choice for applications that may need to be modified or upgraded frequently. They are also commonly used in avionics and military applications, as they are reliable and capable of withstanding grueling conditions.

Working Principle

At its most basic, the 213045-1 consists of two connector shells, each with a metal contact system. The contact system on one shell is designed to make electrical contact with the contact system on the other shell when the two are connected. As each contact is exposed to corrosion, the connector shells are protected by a plastic insulation. The connector shells also have metal ancillary components for creating a secure connection and for installation.

This D-sub connector typically utilizes a solderless connection system, meaning the electrical contacts do not need to be soldered to achieve a connection. This allows for faster and more reliable installation, as well as reduced costs. To make the connection, the contact wires are simply stripped to expose the metal wires, which are then inserted into the appropriate contact areas on the shells. The shells are then manually closed to compress the contacts. This creates an electrical connection and a secure physical connection between the two shells.

213045-1 D-sub connectors are an excellent choice for countless applications and offer the advantages of cost, reliability, and a solderless connection system. Their durable design and simple installation make them a great option for both commercial and military use.
