51939-430LF is a backplane connectors specialized, and is designed to be used in communication, computer, industrial equipment, instrumentation and automotive applications. It is a two row, right angle, vertical mounting board-to-board connector with 13 and 15 contacts, respectively. The connector has high current carrying capacity, low profile design, safe locking mechanism and superior shielding performance.

51939-430LF connectors are made of dielectric material, which offers superior electrical performance and durability. The contacts are gold over nickel plated for maximum electrical conductivity and corrosion resistance. The operating temperature range is -60°C to + 105°C, and the rated current is 10A per contact. It has a grounding mechanism which ensures electrical continuity and EMI/RFI shielding.

The working principle of the 51939-430LFÂ connector is relatively simple. It features a dual compression board interconnect system consisting of two rows of terminal columns. Each row has 13 contacts arranged in one column and 15 contacts arranged in two columns. The contact system is designed to provide a secure connection between two printed circuit boards. The contact lance is inserted into a plated thru-hole on the board, while the guide tab extends into a corresponding through-hole on the mating board. The outer row of contacts is also positioned to provide electrical continuity between the two boards when the connectors are mated.

The dual compression board interconnect system also features a high-current carrying capacity, allowing for the usage of larger currents with minimal power dissipation and resistance. This makes the 51939-430LFÂ an ideal choice for applications where continuous power is required. Additionally, the connector features low signal transmission loss, excellent EMI shielding performance and superior thermal/mechanical performance.

The 51939-430LFÂ backplane connector is a reliable and versatile solution for a variety of high-speed, high-density applications. It offers superior electrical performance, low profile design, safe locking mechanism and superior shielding performance. It is perfect for use in communication, computer, industrial equipment, instrumentation and automotive applications.
