Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) is an area that encompasses a wide range of connectors used to connect two boards together in a variety of applications. The DF40C-70DS-0.4V(52) is a type of connector within this field that is especially well-suited for use in connection with high-speed signaling or data transmission between two boards. In this article, we will discuss the application field and the working principle of this connector in detail.

DF40C-70DS-0.4V(52) Application Field

The DF40C-70DS-0.4V(52) connector is designed for use in a variety of applications, including but not limited to the following:

• Computer motherboards and backplanes
• Automotive electronics
• Lighting systems
• Industrial process control equipment
• High-speed data transmission equipment
• Test and measurement equipment

Due to its small size and robust design, this connector is well-suited for use in situations where space is limited and weight is important. It is also suitable for use in high-vibration environments since it has the ability to maintain its electrical integrity in the event of mechanical shock or vibration.

DF40C-70DS-0.4V(52) Working Principle

The DF40C-70DS-0.4V(52) is a mezzanine connector that consists of two subassemblies: a receptacle and a plug. Each assembly features two rows of 18 gold-plated pins spaced 0.4mm apart. The pins in each row are arranged in an alternating pattern with a center pin in the center of the row.

The two subassemblies are connected by a series of metal tabs that interlock to ensure a secure connection. The tabs also provide additional support and rigidity to the connector to ensure stable performance under varying conditions. Additionally, the connector is designed with a polarizing key which only allows the connector to be plugged in one direction. This feature helps prevent mis-connections and ensures the correct orientation of the two boards in relation to each other.

The DF40C-70DS-0.4V(52) connector also features a four-point contact system that provides maximum contact resistance to improve the reliability and signal integrity of the connection. This four-point contact system is designed to provide superior electrical performance with low crosstalk and superior return loss. Additionally, the connector is designed to withstand extreme temperatures and environmental factors, making it a good choice for applications where high levels of vibration and shock are present.

Conclusion

The DF40C-70DS-0.4V(52) connector is highly versatile and is suited for a range of applications that require high-speed signaling or data transmission between two boards. Its small size and robust design make it a good choice for applications where space is limited and weight is important. Additionally, its four-point contact system and polarizing key provide superior electrical performance while ensuring a reliable connection.
