D-Sub Connectors: 242A12920X Application Field and Working Principle

D-sub connectors are one of the most common types of electrical connectors used today. They are preferred for their cost-effectiveness and ease of use. The 242A12920X is a 9-D Subminiature connector, which is used in a variety of applications, most of which involve networking and communication modules. This article will discuss the application fields and working principle of the 242A12920X.The 242A12920X is primarily used as a low cost, high-speed connector in Ethernet, CAN, RS-232, and USB-based applications. This D-sub connector is designed for use in space-restricted applications. It features two rows of 9 pins and a shell size of 9.810mm, making it compact and cost-effective. It also has a dielectric strength of 500V AC and a maximum operating temperature of 85°C.The 242A12920X features a number of important features which makes it suitable for a wide range of applications. Firstly, it is designed to provide excellent mechanical reliability, making it suitable for applications with regular plugging and unplugging. It also features a 2 or 3 point, positive latching system which ensures that the connection is secure during operation. Furthermore, the 242A12920X meets EMC and EMI regulations, making it an ideal connector for applications which require noise immunity. Additionally, its high-temperature silicone gasket seals the connector for IP50 protection against environmental elements.In terms of working principle, the 242A12920X consists of two parts, namely the main plug and contact pin. The plug is typically made from a range of materials, such as high-grade copper alloy and aluminum alloy. The pin is usually made of brass and is plated with gold or rhodium for increased corrosion resistance. The plug is inserted into the female connector and is secured with the latching system. The contact pin then connects the main plug to the conductor.In summary, the 242A12920X is a highly versatile 9-D Subminiature connector which is suitable for a wide range of applications. It is designed to provide excellent mechanical and electrical reliability, and it also meets EMC and EMI regulations. It has two rows of 9 pins and is designed to fit in space-restricted applications. Furthermore, it features a 2 or 3 point, positive latching system and a high-temperature silicone gasket for IP50 protection against environmental elements. The working principle of the 242A12920X is simple, and it consists of the plug and pin which make the electrical connection when the plug is inserted into the female connector.
