Backplane connectors are used in a variety of connections within electronic devices, from computers and cell phones to audio visual systems and digital surveillance equipment. The 51939-173LF is a specialized backplane connector designed to meet the specific needs of industrial applications. It is compact and designed for use in areas of limited space, allowing for reliable connections with a minimum of size constraints. In addition, its signal contacts have special features to achieve improved transmission rates and signal integrity when compared to conventional connectors of the same type.

The 51939-173LF is designed primarily for power, signal, and data transmission between components in circuit boards. It is well suited for use in server applications, where space is typically at a premium. Its molded housing is rated for operating temperatures from -55 to +125 degrees Celsius and is designed to keep out dust, grime, and other environmental hazards. It also features excellent EMI shielding, an important feature when using sensitive digital components.

The 51939-173LF\'s configuration includes a power contact assembly that deploys an internal "spring latch" mechanism. This latch allows for positive latching of the connector to the board while simultaneously increasing the pin retention force. This increased retention ensures reliable contacts over a wide range of environmental and vibration conditions. The molded housing also includes a sturdy guide button designed to aid in precise alignment of the connector and ensure consistent alignment of the power contacts.

Additionally, the 51939-173LF features a 3-stage signal contact assembly design. This design uses higher contact chest heights than typical connectors, which improves contact quality and reduces the amount of force needed to mate the contacts. It also allows for the contacts to be relieved of stress and strain incurred during temperature cycling. Furthermore, the contacts have been treated with a coating to further increase their resistance to mechanical and environmental wear.

In addition to its excellent power and signal contacts, the 51939-173LF has a signal ground assembly. This ground assembly contacts the PCB itself, providing a path for shielding from EMI. Additionally, the noise is further reduced by the incorporation of a noise cancellation design to the ground contacts.

The 51939-173LF is designed to provide reliable connections in tight spaces. It has excellent power and signal contacts and can take a large amount of abuse before being damaged. Its 3-stage signal contact design, along with the noise cancellation design, ensures excellent signal integrity. The internal latch mechanism and sturdy guide button provide consistency when connecting the power contacts. It is well suited for use in server applications where space is limited, as well as a variety of other industrial applications.
