Introduction

The 51939-587LF is a backplane connector designed for use in applications where power supplies and/or signals must pass through a single connector connecting multiple PCBs. The 51939-587LF is designed to be extremely simple, while providing dependable communication and power transfer capacities. This article will discuss the application field and working principle of the 51939-587LF.

Application Field

The 51939-587LF is perfect for applications which require communication and/or power transfer between multiple printed circuits boards. It is commonly used to connect PCBs in computing systems using the 6U standard, and is particularly well-suited for use in cases where the amount of space required to place two PCBs in close proximity is limited, such as in embedded systems. Additionally, it can be used in applications where shock and vibration resistance is a concern, as the 51939-587LF has been designed for maximum resilience in rough environments.

Working Principle

The 51939-587LF is a connector that works by allowing contacts from one printed circuit board to make contact with the matching contacts of the other printed circuit board, enabling both communication and power transfer capacity. It accomplishes this by having a row of single pin contacts attached to one side of the connector, and a corresponding row of receptacle contacts attached to the opposing side. This configuration allows both the power and communication signals to be fed through the connector.

The 51939-587LF also contains a built in switch mechanism which ensures that even if the physical connection between the two PCBs is faulty, no power is transferred between them. This is accomplished by having the switch mechanism switch the power on and off as the connector is engaged and disengaged from the two PCBs, ensuring that no power is transferred in cases where the connection is faulty.

Conclusion

The 51939-587LF is a specialized backplane connector designed for use in applications where power supplies and/or signals must pass through a single connector connecting multiple PCBs. It is particularly well-suited for use in cases where the amount of space required to place two PCBs in close proximity is limited. The 51939-587LF works by allowing contacts from one printed circuit board to make contact with the matching contacts of the other printed circuit board, enabling both communication and power transfer capacity.
