This connector is an economical solution for connecting power, communication and control systems that require reliable performance even under harsh conditions. It offers a wide range of contact sizes, from 2 to 20 contacts, which gives it great flexibility in terms of application possibilities.

Application Field

The 51939-701LF is ideal for use in a wide range of applications, such as automotive, industrial, networking, and telecommunications. It is suitable for applications where heat-resistance, vibration, and noise immunity are required, such as powertrains, which operate at high temperatures and subject to high levels of mechanical and electrical shock. In addition, these backplane connectors are also suitable for applications in areas where high data rates and minimal crosstalk are needed, such as signal integrity and communication systems. Its high temperature rating and isolation characteristics make the 51939-701LF an ideal choice for high-temperature applications.

Working Principle

The 51939-701LF backplane connector consists of several components that work together to ensure optimal performance. Its terminals are made of high-temperature aluminum alloy and have a uniform coating of high-temperature, plated nickel. The terminals are spring-loaded and have an adjustable plunger for varying contact force, which helps to minimize crosstalk and maximize signal integrity. The contacts are made from a low-profile, high-density composite material, designed for high-speed data integrity and durability. The contacts also have low contact resistance and provide superior thermal and electrical isolation, which is ideal for applications that require low failure rates and high electrical performance.

Additionally, the 51939-701LF also has an innovative side-plunger design that allows for easy and intuitive installation. The side-plunger design increases the contact interface area and allows for higher electrical performances. The contacts are arranged radially in an industry-standard rosette configuration to increase the signal integrity of the cable assembly. The contact pins come in an array of sizes ranging from 2 to 20 contacts and have different levels of insertion force, contact dust protection, and additional noise suppression benefits.

Conclusion

In conclusion, the 51939-701LF backplane connector is a specialized product designed to offer optimum performance in harsh environment applications. It has a wide range of contacts sizes, high temperature operation, and high signal integrity features that make it an ideal solution for automotive, industrial, networking, and telecommunications applications. Its innovative side-plunger design makes installation intuitive and provides high-speed data integrity with low contact resistance and superior thermal and electrical isolation. The 51939-701LF backplane connector is a reliable, economical solution for connecting power, communication, and control systems that require reliable and robust performance.
