Introduction

Backplane connectors come in many shapes and sizes and vary greatly in application and functionality. One such type of connector is the 70453-1303, which is manufactured by L-com. This connector is a specialized backplane that features a forward-facing cable channel and a 120-degree keyway. It is designed to be used in applications that demand high-density cabling, as well as signal integrity and durability. In this article, we will take a closer look at the application field and working principle of the 70453-1303.

Application Field

The 70453-1303 connector is specifically designed for use in board-to-board and board-to-cable applications. The narrow panel width permits easy integration into dense applications, where space is at a premium. The cable channel is optimised for use with RG-style cables, enabling the use of thicker cables without eating into the space available above the board.The 70453-1303 is also designed to be used in applications where signal integrity is critical. The 120-degree keyway ensures that the connector is securely seated and makes contact with the board, providing a reliable signal path. In addition, the rugged design of the connector ensures that it can withstand the rigours of high-vibration environments.

Working Principle

The 70453-1303 connector is designed to provide reliable performance in a wide range of applications. The connector features a high-density forward-facing cable channel, which enables the use of thicker cables without impacting the board design. The channel ensures that the cable is securely held in place, preventing accidental breakage or misalignment.In addition, the high-density nature of the connector also ensures that it can make secure contact with other components. The generous contact area ensures that a secure connection is made, allowing for efficient signal transmission.The connector also features a 120-degree keyway, which ensures that the connector is securely seated. This makes it more reliable in applications where vibration is present. The design also ensures that the connection between the connector and board is secure, ensuring reliable signal integrity.

Conclusion

The 70453-1303 is a specialized backplane connector designed for use in board-to-board and board-to-cable applications. The cable channel is optimised for use with thick cables, while the 120-degree keyway ensures that the connector is securely seated. It is designed to provide reliable performance in high vibration environments, as well as efficient signal transmission.
