74213-202LF is a Hirose Electric rectangluar array edge type mezzanine connector. Its characteristic leads to versatile applications in many types of electrical equipment. In this article, we will explore the applications and working principles of the 74213-202LF.

Applications

The 74213-202LF is designed to provide an interconnection between two printed circuit boards (PCBs) that are mounted side-by-side. This means that it can be used for a wide range of applications that require a reliable, high-speed, reliable means of connecting PCBs. Examples could include industrial control systems and robotics, automotive navigation and entertainment systems, medical equipment, or even aerospace. Due to its compact form factor, low profile, and superior signal integrity, it is often seen in applications where space is at a premium.

Additionally, the 74213-202LF offers a variety of options for current-carrying capacity and mounting styles. It is available in a variety of contact arrangements, from 24 to 124 positions. This versatility, coupled with its robust design and construction, make it suitable for a wide variety of applications and environmental conditions.

Working Principles

The 74213-202LF is a high-reliability rectangular array edge type mezzanine connector. Its design is based on the familiar pin-and-socket configuration, but it provides additional functionality due to the addition of a second layer of contacts between the board-to-board connection. This second layer of contacts provides additional stability and flexibility, allowing the connection to carry higher currents and move more easily when subjected to vibration and shock forces.

The 74213-202LF uses a female-type PC-board mating design and a 4-point contact system. This makes the connector highly resistant to shock and vibration forces, enabling it to maintain its high contact integrity. Additionally, the design of the contacts is such that, even after extended usage, they will still provide reliable electrical connection.

The 74213-202LF is also designed to self-align when it is connected. This allows for a secure and reliable connection between the two PCBs. Additionally, due to the 4-point contact system, the contacts inside the connector are evenly distributed, reducing the risk of contact failure due to unequal loading.

Conclusion

The 74213-202LF is a rectangular array edge type mezzanine connector that offers superior signal integrity and high reliability. With its wide array of applications, robust construction, and its ability to self-align, it is an excellent option for PCB-to-PCB connections in high-speed, low profile applications. Additionally, its wide range of options when it comes to contact arrangements, current-carrying capacity, and mounting styles mean that it can be used in a variety of applications and environmental conditions.
