Backplane connectors are specialized connectors that connect printed circuit boards (PCBs) together in a system or chassis. By connecting multiple boards together in a backplane, the boards can share signals and power. The 51940-216LF is a type of backplane connector that is used for connecting exposed pads on boards. This connector is used in applications where board-to-board height differences are greater than typical connectors allow. Its design allows PCBs with various heights to be connected with a good electrical connection.

Features

The 51940-216LF is a low profile, right angle, through hole backplane connector. This means that only a fraction of the connector is exposed above the PCB, making it suitable for tight spaces and high density applications. It features a simple design with few components. The connector has positive latching and retention characteristics. This provides a secure connection and safe operation in difficult environments. It is designed to be robust and suitable for high current applications with a maximum rated current of 16A per contact.

Applications

Due to its high durability and robustness, the 51940-216LF is suitable for a wide range of applications. It is commonly used in exposed pad applications, where the PCBs are parallel to each other. This connector is popular in medical, industrial and military applications, due to its reliable performance and strength in tough conditions. It is commonly used in high power applications, such as motor control boards, medical imaging systems and power supplies. The connector is also used in communications systems, such as routers and switches.

Working Principle

The 51940-216LF consists of three main components: the insulator, contacts and guides. The insulator is made from non-conductive plastic material, which provides a structural support and insulation. This is important in applications where multiple boards are connected to avoid accidental shorting. The contacts are plated pins, which provide the electrical connection between the two boards. The guides ensure that the connector is correctly installed and that the two boards are correctly aligned. In operation, the electrical signals and power are transmitted between the two boards by the contacts.

Conclusion

The 51940-216LF is a robust and reliable backplane connector. It features a low profile design and is suitable for high current applications. It is designed for exposed pad applications, where the PCBs are parallel to each other. This connector is used in a variety of applications, including medical, industrial and military systems. Its simple design and reliable performance make it an excellent choice in many applications.
