Introduction to D-Sub Connectors

D-Sub connectors are a type of electrical connector, commonly used in various electronic systems and are characterized by their rectangular pins, arranged in two rows or more and mounted on a plastic shell. Their design is often used when a large number of contacts are needed. Traditionally, D-Sub connectors were made primarily of metal, such as aluminum or nickel-plated steel, but modern connectors can also be made of plastic or polycarbonate.The ‘D-Sub’ refers to the shape of the pins and the two rows of connectors which are affixed to a plastic housing. The ‘D-Sub’ name comes from their two rows of pins, which create a “D” shape when viewed from the side. The most common D-Sub connectors are the 9-pin and the 15-pin connectors.

189-025-313R691 Application Field and Working Principles

The 189-025-313R691 is a 3-row, 52 total pin D-Sub connector. It is used primarily in industrial machinery and applications that require more than 3,000 volts of electrical power. This connector is designed for multiple line, low voltage power applications. It features two rows of pins that are arranged in a ‘D’ shape, plus one row of pins that are arranged in an inverted ‘D’ shape. The connector also comes with a metal shell for durability and protection.The 189-025-313R691 is designed for use in low-voltage applications up to 3,000 volts and has the ability to handle currents of up to 20 amperes. It also has a variety of mounting options, including panel mount, cable mounting, and back panel mount. The connector also features a built-in strain relief system that prevents the connector from loosening or damaging itself due to external forces.The 189-025-313R691’s working principle is simple and efficient. The connector’s pins are made of metal, which allows an electrical current to flow between them easily. The connector’s metal shell also serves to protect the pins from damage and serves to provide additional structural support. The connector’s strain relief system helps to ensure that the connection between the pins is secure and that it will not be damaged due to external forces.

Conclusion

The 189-025-313R691 is a versatile and powerful D-sub connector that is well-suited for use in high-voltage industrial applications. This connector offers a number of features, including a metal shell for increased strength and protection, and a built-in strain relief system that prevents the pins from loosening or becoming damaged due to external forces. Additionally, the 189-025-313R691 is capable of handling currents of up to 20 amperes and is designed for use in low-voltage applications up to 3,000 volts.
