Rectangular connectors are used in many different connection applications, such as computer and electronic systems, industrial control systems, automotive wiring, and life sciences. Many of these connectors provide power, signal, or both at the same time, and they generally come in two types: headers and receptacles. DF11-4DS-2V(20) is one of the most popular rectangular connectors, providing reliable power and signal with its 20-pin configuration. But what are the application field and working principle of this connector?

Applications of DF11-4DS-2V(20)

DF11-4DS-2V(20) is a common type of power supply and signal connector with four-way spacing in a high-density package. It is widely used in automotive, video, and industrial control applications, and its 20-pin configuration can support up to 8A current carrying capacity. The 0.8mm contact pitch helps to reduce the overall size and weight of the connectors, while the high-density design ensures minimal contact points and reduces crosstalk and interference. The solder tails on both sides of the connector also provide better stability of the connection. In addition, this connector is also very suitable for automated assembly applications.

Working Principle of DF11-4DS-2V(20)

DF11-4DS-2V(20) utilizes a spring-loaded contact system for signal, power, and shielding connections. There are three contact areas: the top contact area, where the shield is connected, and the two side contact areas, which are used for signal and power. The connector also uses a two-stage contact system, where the first-stage contacts are made at the first contact area and the second-stage contacts are made at the second contact area. The contact area is protected by an epoxy-gel coating, which ensures a reliable connection without any signal interference.

Advantages of DF11-4DS-2V(20)

The DF11-4DS-2V(20) utilizes a very reliable two-stage contact system, which improves the connector’s power and signal reliability. In addition, its small size and high-density design make it ideal for use in tight spaces or automated assembly applications. The connector also offers good environmental protection due to the epoxy-gel coating and solder tails on both sides. Finally, the connector’s 20-pin configuration increases its current carrying capacity to 8A.

Conclusion

DF11-4DS-2V(20) is a popular rectangular connector offering reliable power and signal connections. It is used widely in automotive, video, and industrial control applications, and its 20-pin configuration can support up to 8A current. The connector’s two-stage contact system improves its power and signal reliability, while the epoxy-gel coating and solder tails on both sides offer good environmental protection. In addition, its small size and high-density design make it suitable for use in tight spaces.
