51939-812LF

Backplane connectors are an essential part of any electrical system, providing a connection between electronic components and an electronic backplane. Despite their ubiquity, different types of connectors feature vastly different application fields and working principles. The 51939-812LF is an outstanding example of a specialized backplane connector that features a number of unique characteristics.

Physical Characteristics

The 51939-812LF is a type of vertical-style connector, meaning it is designed to connect two or more components in an upright orientation. It features a rugged Diecast zinc housing, providing superior durability and enabling it to be used in high-vibration environments. The 51939-812LF’s contact points are made of gold and feature a selective gold plating, making them more durable and resistant to corrosion than other types of contacts.

Application Fields

The 51939-812LF connector is particularly useful in applications where space is at a premium. Its slim form factor and the fact that it can be mounted directly onto a printed circuit board make it ideal for use in space-constrained systems. Additionally, its Duracoat finish helps reduce aberrant movement, making it highly suitable for use in machines that experience a lot of vibration. The 51939-812LF connector can also be used in industrial automation, communications systems, and automotive applications.

Working Principle

The 51939-812LF connector features a hinged plate, which is connected to the pin receptacle through a spring. This hinged plate helps keep the pins in alignment and prevents accidental disconnection. As mentioned earlier, the contact points are made of gold and feature a selective gold plating. This increases the connector\'s durability. Additionally, the contact is designed to make a secure connection between the connector and the circuit board, guaranteeing that the connection will remain stable throughout vibration and wear and tear.

Conclusion

The 51939-812LF is a specialized backplane connector that features a number of unique characteristics, making it particularly well-suited for use in space-constrained, high-vibration applications. Its rugged diecast zinc housing, gold contacts with selective gold plating, and hinged plate that prevents accidental disconnection all come together to make the 51939-812LF one of the most reliable connectors for use in industrial automation, communications systems, and automotive applications.
