D-Sub Connectors

D-Sub connectors, also known as D-Subminiature connectors, are a type of subminiature electrical connector typically used for computer and communication applications. They are named for their characteristic D-shaped shell. These connectors can be divided into two groups, high-density and standard. Within each group, several sizes exist, with the number of possible positions, shell sizes, and number of conductors varying with each size.

DAO3V3P543A40LF application field and working principle

DAO3V3P543A40LF is a D-Sub connector designed for high-density applications. This type of connector truly stands out among many other types of subminiature connectors. It can support up to 43 pins, has a shell size of 3.3 mm, and provides three levels of polarization to ensure that the mating of the connector is correct. It is most commonly used in applications such as industrial automation, multimedia home entertainment, and other telecommunications.

The DAO3V3P543A40LF is designed with a contact-crimp connection. This type of connection uses a plastic shell containing terminals, which are then crimped on the conductors. This makes the connection able to withstand vibration and other high-stress conditions. The contacts are designed with a high purity copper alloy, which provides high electrical and mechanical performance. Additionally, the connector shell is constructed of aluminum nickel steel., which ensures that it can provide excellent corrosion protection while also providing high-strength mechanical performance.

The locking system of the DAO3V3P543A40LF ensures a secure connection between the male and female connectors. It features a tab and groove system, which provides a secure connection without any accidental disconnection. This locking system is also effective against vibration and shock. Additionally, the metal components of the connector are silver-plated for better contact and protection from corrosion.

The DAO3V3P543A40LF also has a waterproofing capability. It is rated for an IP67 level of immersion in water, meaning that it is suitable for outdoor and submersion environments. This ensures that the connection is waterproof and safe for numerous applications, even in harsh environments.

The DAO3V3P543A40LF is a robust and versatile connector, making it a great choice for many applications. It offers excellent electrical and mechanical performance, as well as a secure connection. This makes it suitable for a wide variety of uses, from industrial automation to home entertainment. With its waterproofing capabilities, it is perfect for outdoor applications or areas where water exposure is expected.
