Introduction

Sockets for ICs, transistors, and other circuit components are an integral part of an electronics assembly. It allows engineers and technicians to quickly and easily install a component on the circuit board. Sockets provide a wide range of advantages over direct soldering or wave soldering. In this article, we’ll discuss the application field and working principle of 25-0501-21 socket.

Application Field

25-0501-21 socket, which utilizes a dual beam contacts with floating contact pad, is specifically designed for MIL-STD-1553 applications. It is a reliable contact system designed to work with MIL-STD-1553B high-speed buses. The socket can be used to route signals between the circuit board and the external world, ensuring robust and reliable connections even in the presence of high noise and vibration.The socket also features a unique design which allows two contacts to be located next to each other, resulting in a smaller total footprint. This feature makes it easier to fit within the space available on the circuit board and allows for more room for other circuit components. In addition, the socket can accommodate a wide range of PIN and socket combinations and offers a choice of two lead finishes.

Working Principle

The working principle of 25-0501-21 socket is based on the dual beam contact system, which is designed to ensure a reliable connection even in the presence of high vibration. Two copper beams are connected to each contact pad, which means that contact is made directly between the lead and the contact pad without any air gap. This design ensures a consistent connection regardless of how the socket is moved or rotated.The socket also features a floating contact pad, which helps to ensure a reliable connection even when the device is exposed to temperature variance. The contact pad is moved with the lead so it remains in contact with the contact pad within the socket even as the device heats up or cools down. This helps to ensure a reliable connection even when the device is exposed to\'s harsh environmental conditions.

Conclusion

25-0501-21 socket is an excellent choice for MIL-STD-1553 applications. It features a reliable dual beam contact system with floating contact pad, making it suitable for a wide range of PIN/socket combinations as well as two lead finishes. This socket is designed to ensure a reliable connection even in the presence of high vibration and temperature variance.
