<h1>D-Sub Connectors</h1><p>D-sub connectors are a type of connectors with a rectangular shape and multiple parallel contacts. They are used for many different electronic systems, and can provide a reliable connection for data, video, and power. The D-sub connector family includes a wide variety of connectors with different sizes and contact arrangements. One of the popular members of the family is the type known as the 747303-2</p><h2>747303-2 Application Field and Working Principle</h2><p>The 747303-2 D-sub connector is widely used in the telecommunications and networking industries. The 747303-2 connector features 11 male contacts and a user-friendly locking snap-in feature. It is a popular choice for connecting digital devices, such as modems and routers. The male end of the connector is usually found on the end of a patch cable or a wall plate.</p><p>In terms of its application field, the 747303-2 connector is commonly used to connect audio-visual equipment, such as TVs and projectors. It is also used in other general-purpose electronic devices, such as computers, servers, and power supplies. It is especially suitable for situations where a reliable, dust-proof connection is required.</p><p>In terms of its working principle, the 747303-2\'s male contact features a stainless steel shell and a tension-type spring design. When it is connected with its female counterpart, the contact is covered by a dielectric layer, which enhances the connection\'s dust resistance and stability. Additionally, the dielectric layer also helps protect the connectors from corrosion, ensuring a reliable and secure connection.</p><h2>Conclusion</h2><p>The 747303-2 D-sub connector is a popular and reliable choice for connecting digital devices, such as modems and routers. It also features an outstanding dust-proof and corrosion-resistance design, making it a suitable choice for applications in telecommunications, networking, and general-purpose electronics.</p>
