Backplane Connectors - Specialized : 51940-551LF Application Field and Working Principle

The 51940-551LF is a specialized Backplane Connectors (BPC). BPCs are a type of electrical connectors which connects different circuit boards and other components within a system housing or chassis. This type of connector is used especially in high-performance systems and applications.The 51940-551LF is a specialized BPC which has been designed for high-performance systems. It is a two-row through-hole device with pins on both sides. The device is designed to ensure maximum contact and reliability and is suitable for applications where high-current, high-frequency and high-voltage signals need to be transmitted. It can also be used in applications where impedance control is required.The 51940-551LF is a unique BPC in that it is designed to transmit high-accuracy signals within a wide temperature range (from -40 to +85°C). It is also designed to reduce the electromagnetic interference (EMI) which is present in some types of electronic equipment. This makes it suitable for applications found in avionics, automotive and telecommunications.In terms of working principle, the 51940-551LF BPC works by transmitting electrical signals through its pins. The signals are transmitted from the printed circuit board (PCB) to the connector, which then transmits them to the other components of the system in a highly accurate manner. This data transmission is achieved by using differential signal pairs, allowing for more accurate and reliable data transmission. Furthermore, the signals are filtered using additional features which reduce EMI.The 51940-551LF also uses a special plating technique for its contacts. The contacts are plated with a corrosion-resistant alloy which provides good electrical conductivity while still providing a long life for the device. This plating technique also helps to prevent electrical arcing and provides a robust resistance to shock and vibration.Overall, the 51940-551LF is a specialized BPC designed specifically for high-performance applications. It is designed for use with PCBs as well as for use as stand-alone components. It is designed to transmit high-accuracy signals within a wide temperature range while also reducing EMI. It is highly reliable due to its use of differential signal pairs, corrosion-resistant alloy plating and robust resistance to shock and vibration. This makes it a great choice for applications such as avionics, automotive and telecommunications.
