Introduction

Backplane connectors include two main types specifically designed for different applications. The first type is the 51939-846LF series, which is exceptionally well suited for backplanes with high numbers of pins. This type of connector provides a low profile and can operate in varying environmental conditions, making them one of the most reliable connectors on the market. It is also capable of carrying high amperages of power and can handle signals up to 1 GHz. In this article, we will discuss the 51939-846LF application field and working principle.

Applicationfield

The 51939-846LF series is a popular choice for use in many industries, such as aeronautics, aerospace, telecommunications, and medical equipment. It is also suitable for use in military and instrumentation backplanes, as well as for industrial automation and process control applications.The 51939-846LF offers several advantages over other backplane connectors. It is designed to be highly reliable, with an impressive tolerance to shock, vibration, and extreme temperature ranges. It also reduces the signal path between paired components, making it ideal for applications with high-frequency data transfer. Additionally, this type of connector requires minimal space due to its low profile, and it is designed to work in almost any environment.

Operation principle

The 51939-846LF series primarily uses banana plugs and pins for connection. The banana plugs are connected to the pins on either one or both ends of the connector. When fully connected, they create an electrical connection that allows for electrical current or data signals to flow between the two.The banana plugs provide a mechanical connection that differs from a standard connector. Instead of relying on nuts and bolts to secure the two parts, the banana plugs are inserted into the pins to form a solid link. This makes for a more secure connection that protects against mechanical shock and electrical surges.The signal integrity of the 51939-846LF connector is also impressive. It is designed to reduce signal losses and minimize noise caused by metallic components. The insulation materials also improve the impedance, crosstalk, and return loss performance of the connector. In addition, it has excellent resistance to electromagnetic interference, making it less prone to interference from electromagnetic sources.

Conclusion

The 51939-846LF series is an ideal choice for any backplane application, offering a reliable connection in high pin count applications. It is designed to reduce signal path, making it ideal for applications requiring high-frequency data transfer. Additionally, its insulation materials improve its impedance, crosstalk, and return loss performance. The 51939-846LF is also equipped to handle high amperages of power and can handle signals up to 1 GHz.Overall, the 51939-846LF series has proven to be an extremely reliable and efficient connector that is suitable for numerous applications. It is designed to withstand extreme environmental conditions and can be used to form secure electrical connections.
