Backplane Connectors - Specialized connectors are an important part of computer hardware, providing a reliable, high speed link between components and other hardware. The 51939-347LF is one such example, allowing for a high density connection between PC boards or other devices requiring robustness. Here, we discuss the application field and working principle of the 51939-347LF connector.
The 51939-347LF connector is designed for rugged, low profile applications where shock and vibration are an issue. It is ideal for computer backplanes, particularly in secure, high-speed data transmission applications. It is suitable for use in medical, industrial, communications and automotive equipment.
The 51939-347LF connector is designed for hot plugging, and is designed to ensure that metal-to-metal contact is maintained for reliable operation. It has a low profile, allowing for easy, efficient installation in tight spaces. It has two rows of similarly spaced contacts with a total of 33 pins on each row, and two coded contact strips. It has a low contact resistance of 1.0 mΩ and an insulation resistance of 500 MΩ.
The working principle of the 51939-347LF connector is based on electrical contact being made when the connector is plugged in. The two coded contact strips provide an electrical contact between the two mated parts. When the two parts are mated, the two strips join, and the contacts make an electrical connection. The coding system prevents contact between the mating parts that are not polarised properly. The contact resistance is ensured through the use of a spring element that provides a constant contact force.
The 51939-347LF connector offers superior performance in data transmission, due to its low contact resistance and insulation resistance. It is extremely durable, and can handle shock and vibration without interruption. Its low profile enables it to be installed in confined spaces. The coding system helps to ensure that the two mated parts are correctly polarised, ensuring reliable performance. Overall, the 51939-347LF connector offers a secure, reliable connection for a wide range of applications.
