Backplane connectors are specialized connectors that provide high-speed and efficient electrical connections between pc boards housed in the same enclosure. This type of connector includes a range of products such as edge-mount connectors, surface mount, and through hole options.

A good example is the 51940-391LF application field and working principle. This is a surface mount (SMT) backplane connector that provides 80 mated contacts with a 0.3mm pitch. Its designed to mate with a vertical or right-angle header and provide superior signal integrity performance in the toughest applications.

The 51940-391LF also features an optimized solder-cup design which allows for easy reflow soldering. Moreover, the additional depth of the solder bezel offers superior EMI and RFI shielding that improves signal integrity. The low profile design of this connector allows for close proximity to other components, and provides increased board density that helps to reduce the size of larger enclosures.

When it comes to the working principles of the 51940-391LF, its contact material is made of high-performance beryllium copper alloy that ensures superior electrical and mechanical performance. It also features multiple board-to-board mating capabilities and secure connections without the need for any additional locking mechanisms. Additionally, the connector features a 12-contact design which allows for low profile and robust connections.

In addition, the 51940-391LF features four mounting and grounding points for enhanced stability. It also has a one-piece backshell for convenient stability and cabling needs. Finally, it is designed to reduce mating and un-mating forces, which decreases electrical impedance and improves signal integrity.

The 51940-391LF is a versatile and reliable backplane connector that is ideal for a range of applications including telecommunications, consumer electronics, computers, networking, automotive, and more. It is designed to provide a secure and stable connection with superior shielding, and optimal signal integrity. It also features a straightforward design and solid construction for reliable performance in harsh environments.
