Backplane Connectors - Specialized

The 51952-295LF is a specialized part used for backplane connectors. It is designed for data and power applications that require small size, high density, and a variety of options for interconnections. This connector is used for connecting various components and devices for signal transmission between printed circuit boards. It is also used for blind mate applications. It is especially popular in high speed applications because of its low profile and small size, which provide improved signal integrity and greater flexibility.

Application Field

The 51952-295LF is suitable for a wide range of applications, including computers, telecommunications devices, consumer electronics, medical devices, test and measurement instruments, and industrial robots. The small profile and multiple configuration options make it ideal for connecting components in space-limited environments. It is especially suitable for the transition from legacy systems to modern, high-speed devices. The versatility of the connector helps to reduce the cost of interconnecting different components.

Working Principle

The 51952-295LF utilizes mechanical contact spring technology to help maintain the mechanical and electrical interface. The connector is designed so the spring contact is self-adjusting and able to achieve a low contact resistance in nearly any environmental condition. The spring contact can essentially accommodate any board level misalignment. It has a pull up latch on the housing to ensure secure mating retention forces.

The number of pins and the pitch depend on the configuration chosen. It is available in both single row and double row configurations. Depending on the application, the single row can have up to 65 pins with a pitch of 0.5 mm, and the double row can have up to 128 pins with a pitch of 0.3 mm. It is rated for up to 2 A, 60 Vrms (signal) and 20 A, 120 VDC (power).

Conclusion

The 51952-295LF is a specialized connector used in a variety of high-speed applications and for connecting components in space-limited areas. It is capable of carrying significant amounts of data and power and can accommodate board level misalignments. Small size and versatility makes this one of the most popular solutions when it comes to connecting components to printed circuit boards.
