Introduction to D-Sub Connectors

A D-Sub connector is a type of electrical connector commonly used in computer and electronics equipment. It consists of two or more parallel rows of pins or sockets surrounded by a metal shield. The shield provides electrical isolation for the pins or sockets, which helps to reduce interference between various connectors in the system. D-Sub connectors are available in a wide range of sizes, with the most common being the 9-pin (DB-9) and 25-pin (DB-25) varieties.

1757835-4 application field and working principle

The 1757835-4 is a D-Sub connector specifically designed for Ethernet applications. It is commonly used in 10/100/1000 BaseT, 1000 BaseX and 10 Gigabit Ethernet networks. The connector is, however, also compatible with other protocols such as ATM or Gigabit Ethernet.The connector consists of two parts, the shell and the insert. The shell is made of metal and designed to provide mechanical protection and shieldingagainst interference. The contacts are housed in the insert, which is made of a non-metallic material such as plastic or fiberglass. The insert contains two rows of nine metal contacts each, with an additional two contacts at the end being used for grounding.The connector system is designed to provide an electrical connection between two Ethernet devices. The two parts of the connector are mated together using a compression coupling mechanism, which provides good electrical and mechanical retention. This ensures that the connection is not only highly reliable, but also protected against dust and debris.The contacts of the connector are rated for a maximum current of 1mA. The system also has a high contact resistance of 220 mOhms max. and a dielectric strength of 250 voltsAC or 175 voltsDC.In addition to the electrical specifications, the 1757835-4 connector also meets a number of environmental requirements. It is resistant to shock, vibration and corrosion and can operate in temperatures ranging from -40°C to +130°C.

Conclusion

The 1757835-4 is a D-Sub connector designed for use in Ethernet networks. It is a reliable and durable connector, rated for 1mA current, high contact resistance and a dielectric strength of 250 voltsAC or 175 voltsDC. It is also designed to operate in harsh environments with temperatures ranging from -40°C to +130°C. Its compression coupling mechanism provides good electrical and mechanical retention, ensuring a reliable connection between two Ethernet devices.
