Backplane connectors are a type of electrical interconnection used as an intermediate link between the printed circuit boards and the cable segments in many industrial and communication systems. They provide reliable physical and electrical connections between multiple devices in a system, and can also serve as the means by which the system communicates. This article will explain the application field and working principle of 213090-4 backplane connectors.

Application Field of 213090-4 Backplane Connectors

The 213090-4 backplane connector is a board-to-board interconnect designed for use in applications that require sustained performance in tough environmental conditions. The robust design of the connector helps to ensure reliable interconnections, even when operating in harsh temperature and humidity conditions. These connectors are suitable for use in both industrial and commercial applications, such as those where signal integrity, EMI/RFI noise reduction, or system power management is necessary. The connectors are designed to meet the requirements of the European Standard EN 60309-2 for power connectors and are UL and CE certified.

The 213090-4 connector is available in various sizes to suit different system configurations, and it is suitable for use in multiple industrial and consumer applications, such as telecommunication infrastructure, medical imaging systems, industrial automation equipment, automotive systems, and process control systems. The connectors are available with either screw-type or plug-in retention features, both of which ensure secure mounting and a reliable connection. They also provide a maximum contact force of 0.6 N, ensuring good electrical performance.

Working Principle of 213090-4 Backplane Connectors

The 213090-4 backplane connector is a spring-loaded device that works by maintaining the electrical connection between two boards when mated. The connector consists of a pair of housings that fit together. The housings have contact fingers in them and spring-action locking tab that help to maintain the mating connection. The contact fingers are made of flexible Leaded Tin Bronze (LTB), a material that is strong, corrosion-resistant and provides good electrical conductivity.

The locking tab is designed to be compressed when the two housing halves are mated, forcing the contact fingers against one another and creating an electrical connection between the two boards. This connection is further secured and maintained by the spring-action locking tab, which holds the two housings together while providing the necessary contact force for an electrical connection. The contact force provided by the connectors’ spring-loaded mating mechanism ensures that the connection is reliable, even when dealing with environmental factors like humidity and vibration.

The 213090-4 backplane connector also features a two-part termination system that provides a “toolless” disconnection. This means that it is possible to disconnect the mated connector without using a tool. This feature makes it easy to quickly redeploy the connectors in different configurations or to replace defective parts.

Conclusion

The 213090-4 backplane connector is a reliable and robust board-to-board interconnect designed for use in harsh environment. The connector features a sophisticated two-part locking system that provides secure mating and proper contact force for a reliable electrical connection. This connector is suitable for use in a wide range of industrial and consumer applications, from telecommunication to medical imaging, automotive, and process control systems.
