51940-491LF

Backplane connectors are components which are designed to serve as electrical interconnect between two or more circuit boards or other items in an electronic system. Specialized backplane connectors exist to perform specific tasks or to achieve certain performance characteristics. The 51940-491LF is a specialized backplane connector designed for a very specific application.

This connector is made by a Swiss company called Molex and is designed as a surface mount type of connection, specifically for high speed applications, such as motherboards, computer backplanes and servers. The 51940-491LF has a very low profile height profile of only 5 mm, which makes it suitable for very tight spaces. It is also designed to prevent signal noise, providing a fast transmission rate.

The backplane connector uses a mid-board ribbon system, meaning that it is designed to be used when the board is folded in the middle. This folded configuration allows the connector to apply a shear force to each of the connectors which keeps them securely together. This makes it ideal for applications such as multi-layer boards and servers.

The main component of the 51940-491LF is Molex\'s patented SecureLink, which is a connector that uses a rigid plastic structure to connect the two pieces of the connector. This ensures that the connection is very sturdy and does not easily move or become loose during use. This provides a reliable and durable connection that can handle the high speeds that are normally associated with these types of applications.

The operation of the 51940-491LF is quite simple. The two pieces of the connector are pushed together and the SecureLink locks them together securely. This device is fully compliant with RoHS (Reduction of Hazardous Substances) standards, making it a safe and reliable choice for any application that requires a high speed connection and reliable signal transmission.

The 51940-491LF is a specialised backplane connector with a very specific purpose. Its low profile, high speed capability and rugged construction make it suitable for a range of applications, such as motherboards, servers and multi-layer boards. Its combination of features makes it a reliable and durable choice for any application.
