51939-544LF

Backplane connectors, such as the 51939-544 LF, are components which are used to establish connections between electrical parts within a device. For the most part, these connectors connect the logic printed circuit board (PCB) within the device to the backplane power supply. The backplane is the nervous system of the device and, as such, these connectors must meet rigorous requirements in terms of EMC standards, temperature range, working voltage, contact resistance, and other factors.

Construction

The 51939-544 LF is an \'L\' shaped modular plug contact pin which is designed to fit into through-holes in the PCB. It is typically made of a stainless steel or a nickel-plated brass material with a gold plating for better corrosion protection. The 51939-544 LF has a pitch of 0.635mm and is 8mm in length. This ensures the connector can fit into the tiny through-holes while still providing a secure and reliable connection.

Working Principle

The working principle behind the 51939-544 LF backplane connector is simple. When the connector is inserted into the through-hole of the PCB, the contact pin extends outside and makes contact with the other side of the PCB. This forms a conductive connection which allows the signals and electric current to flow between the two sides of the PCB. The contact pin is spring-loaded which allows it to make sturdier contact with the PCB.

Application Fields

The 51939-544 LF backplane connectors are mainly used for highly reliable electrical links which support a range of high-frequency signals. As these connectors are applied to the printed circuit boards, they offer a stronger and more secure connection than is possible with conventional through-hole components. The connectors can be used in a wide range of applications, including automotive, medical, industrial automation, and consumer electronics.

The high speed and reliability of the 51939-544 LF connectors make them ideal for use in applications where high temperature, shock, and vibration are present. Additionally, they are suited for board-to-board connections in devices such as development boards, motherboards, and power supplies. The versatile and reliable nature of this backplane connector make it an ideal choice for a range of applications.

In conclusion, the 51939-544 LF backplane connector is a reliable and versatile component which offers excellent performance in various application fields. It is a reliable and cost-effective solution for connecting two sides of a PCB with high-frequency signals. The spring-loaded contact pin ensures a secure and reliable connection and makes this connector an ideal choice for a wide range of applications.
