Backplane connectors are a special type of connector used for high-speed data communications between circuit boards and wired systems. The 51940-290LF is a board-to-wire, vertical-mount, blind-mate connector with spring tensions that help enable 3-Volt to 5-Volt differential signal-path integrity. Its simple construction makes it suitable for a wide variety of applications.

Application Field

The 51940-290LF board-to-wire connector is ideal for applications with high-speed, narrow data-rate, short-distance, low-power requirements, making it a great choice for applications such as:

• Industrial control
• Serial ATA
• High resolution multimedia
• MIDI applications
• Automotive infotainment
• Consumer electronics

The connector is designed for applications requiring low-profile, space-saving, high-density solutions. Its blind-mate feature simplifies assembly and requires no soldering, allowing for flexibility in assembly process.

Working Principle

The 51940-290LF connectors feature spring tensions that provide a 3-Volt to 5-Volt differential signal line integrity. The design includes compression springs that bias the signal lines against each other when the connector is mated. The tension maintains the signal integrity across the connector mating surfaces even when faced with vibration or shock. This tension helps minimize attenuation and reduce crosstalk. This both increases signal-line protection and ensures that the communications link remains a reliable, stable data link.

The connector has a slim profile and low-profile vertical mount. This makes the connector suitable for applications where limited space is available. It is also designed for quick installation and removal, with no soldering required. This enables customizable designs, making it easy to add and remove components as needed.

The board-to-wire, vertical-mount, blind-mate connectors provide a low-cost and reliable connection in many applications. With the spring tension line integrity and crosstalk minimization, it is the perfect choice for high-speed, narrow data-rate, low-power applications.
