51939-062LF

Backplane Connectors - Specialized

The 51939-062LF is a specialized, compact 50-contact backplane connector. It is designed for energy-efficient applications such as hard drives, DVD players, tablets, or other slim form-factor applications that require high density connections with smaller pitch. It provides a cost-effective alternative to existing backplane connectors in these types of applications.

The 51939-062LF is a multi-connect conductor, double-row SMT-to-SMT plug-in connector. Each contact is rated for up to 0.4 amps, with an insulation resistance of 1000 megohms minimum. The maximum contact alignment force is 10N. The contacts are arranged in a 13-mm wide, 2.54-mm pitch configuration, allowing 50 connections in 10 x 5 slot configurations. The total thickness of the connected module is just 2.4 mm, ensuring that the connector fits into thin designs.

The contacts of the 51939-062LF are plated with palladium-copper alloy and the bodies feature gold flashing. An elastomeric seal at the entrance and a metal retaining clip at the mouth of the connector provide a secure connection and maximize protection from dust and other contaminants. The design also allows for connection in either direction, allowing the connector to be used in both left-handed and right-handed device configurations.

The working principle of the 51939-062LF is quite simple. Electrical current flows through both ends of the connector, with the positive current entering at one end and the negative current exiting at the other. As the positive current passes through each contact, it creates a small electric field. This electric field produced by the current causes the electrons in the conductor at each contact to migrate towards the contact interface, thereby increasing the electrical current. As the positive current reaches the exit end of the connector, the electrons will reach the interface and combine with the negative current, completing the circuit.

The 51939-062LF is an ideal solution for energy-efficient applications, allowing for a higher connection count, a slimmer profile, and improved signal integrity. Its specialized design allows it to outperform other backplane connectors in these applications, providing a cost-effective solution that helps maximize efficiency.
