Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board): 52465-4091 Application Field and Working Principle

Rectangular connectors are one of the most important types of electrical connectors, and their use is wide-ranging. In this article, we take a look at two of the most common types of rectangular connectors - arrays, edge types, and mezzanine (board-to-board) connectors - and discuss their application fields and working principle. Specifically, we focus on the 52465-4091 type of mezzanine connector and explain its salient features.

Application Fields

A mezzanine (board-to-board) connector such as 52465-4091 is mainly used to connect two printed circuit boards (PCBs). These connectors have a wide range of applications because of their electrical properties:

• Power supply (for example, Li-Ion batteries)
• Vehicle Cables
• Communications and data transfer
• Automotive electrical systems
• Consumer electronics

These connectors are preferred for their high degree of reliability and durability. They are also ideal for applications where they must be frequently mated and unmated, as they are designed to withstand repeated mating and unmating. For example, they are used in Wi-Fi systems, where two printed circuit boards must be connected and disconnected via a connector several times.

Working Principle

The 52465-4091 mezzanine board-to-board connector is a two-row, right angle connector that features high-performance contacts. It has two sets of contacts that mate adjacent to each other and form an electrical connection between the two circuit boards.

The 52465-4091 connector has two rows of pins in a staggered arrangement, and it features four signal contacts and eight power contacts. The signal contacts are designed to prevent crosstalk, minimise noise, and ensure high integrity in data and communication applications. The power contacts are designed for higher current-carrying capability.

The connector features high-quality components and is designed to be durable. It has a current rating of 5.0A DC (max) and a voltage rating of 125V AC (max). The pin spacing is 0.5mm and the contact resistance is 20m (max). The insulator material is thermoplastic, and the contact material is phosphor bronze. The connector has a dielectric withstanding voltage of 500V AC (min).

Conclusion

In conclusion, the 52465-4091 mezzanine (board-to-board) connector is a two-row, right angle connector that is designed for reliable electrical connection between two printed circuit boards. It has a wide range of applications, and it features high-quality components. It has a current rating of 5.0A DC (max) and a voltage rating of 125V AC (max). The pin spacing is 0.5mm and the contact resistance is 20m (max). The dielectric withstanding voltage is 500V AC (min).
