Introduction

Backplane connectors, specialized, such as the 50576-5128ELF, offer a unique form factor designed to bring a wide range of applications to wire-to-board coupling. The 50576-5128ELF in particular leverages a cost effective, low profile plastic body and contacts meant for multiple uses with space limitations within a tight package. Here, an in-depth overview of the 50576-5128ELF application field and working principle will be presented.

Application Field

The 50576-5128ELF is an excellent choice for applications such as severs, routers, switches, desktop computers, and notebook PCs. Additionally, with its small form factor, this connector is a great solution for applications such as industrial automation and instrumentation, as well as telecommunications, wireless and storage applications.

Working Principle

The 50576-5128ELF features a low profile plastic body designed with two off-board mating surface vias to allow connection to a wire via a board or panel edge. This low profile design reduces potentially costly weight and payload issues posed by other solutions. The 50576-5128ELF also has two pitch variants—1.5mm and 1.27mm. This allows for compatibility with board-to-board and wire-to-board solutions.The 50576-5128ELF connector also features a locking system designed to direct the user’s attention to the connector’s plug or unplug status. This helps to prevent accidental mis-mating of the connection. The locking system also ensures secure mechanical engagement.Lastly, the 50576-5128ELF features contacts made from steel which offer superior contact force and electrical performance. The contact design also helps to ensure a reliable connection over the life of the system.

Conclusion

The 50576-5128ELF is a versatile, low cost, low profile backplane connector designed to offer multiple potential uses in various applications. Its features, such as two pitch variants and a locking system, make it a great solution for applications such as severs, routers, switches, desktop computers, and notebook PCs, as well as industrial automation and instrumentation, telecommunications, wireless, and storage applications. With its superior contact force and electrical performance, it helps to ensure a reliable connection.
