Introduction to D-Sub Connectors and 745189-7

D-sub connectors (or D-subminiature connectors) are electrical connectors designed to mate two cable or circuit board assemblies. They use a standard metal shell and standardised pin configuration and spacing, allowing them to be used with a wide variety of equipment and cables. The 745189-7 connector is one of the most commonly used varieties of D-sub connectors.

Design of 745189-7 D-Sub Connectors

The 745189-7 connector has a standard metal shell that is typically made of stainless steel or zinc. This metal shell houses a male or female connector, depending on the type of cable or device it is intended to mate with. Inside the shell are multiple pins, usually ranging from 9 to 50 contacts, depending on the size of the 745189-7 connector. The pins are arranged in a square pattern with a certain number of pins in each row and column. The pins are typically made of stainless steel and are gold plated to ensure reliable and corrosion-resistant connections.

Application Fields and Working Principle of 745189-7

The 745189-7 D-sub connector is commonly used in a variety of applications. It is most frequently used to connect computers to peripherals, such as keyboards, printers, and scanners. It is also used in data communication and audio/video equipment, medical equipment, industrial control systems, and automotive systems.The working principle of the 745189-7 is relatively simple. When the male connector of the 745189-7 is inserted into the female connector, the male pins are pressed against the metal contacts in the female connector, establishing an electrical connection. The male pins and contacts are designed in such a way that they can withstand up to 250V of power and up to 50A of current. This ensures reliable and long-lasting connections.

Conclusion

The 745189-7 connector is a versatile and reliable D-sub connector suitable for a variety of applications. It is available in multiple sizes and can be used to establish reliable electrical connections with up to 50A of current. This makes it the perfect choice for connecting computers to peripherals, data communication and audio/video equipment, and industrial control systems.
