202516-3 Connectors, Interconnects

Backplane Connectors, such as 2051-16-3, are an essential part of modern connected systems and are typically used in high-speed, industrial applications. Not only do they provide high-speed transmission of data and power, but they also allow for greater system density and efficient system design. The 2051-16-3 Backplane Connector is designed for use in highly ruggedized applications, offering reliability and performance in tough environments.

Design

The 2051-16-3 backplane connector is constructed of a heavy-duty plastic housing that incorporates two-piece terminal contacts, each consisting of four gold-plated contacts. The connector is designed to be fully interlocked, allowing the terminal contact to be secured in the connector. The four-pin socket gives the advantage of a double-stacking surface, so a circuit board of double thickness can be plugged into the same connector. The 2051-16-3 is designed to meet the severe requirements of extended life in commercial aircraft, industrial, and military applications.

Application

The 2051-16-3 connector is suitable for a wide variety of backplane connection applications, including card cages, PCBs, and network systems. It is designed for installation and removal from both sides of the PCB, making it especially suitable for double-sided applications. This connector is particularly useful for high-density situations, as its design facilitates the use of highly dense circuitry. Additionally, its two-piece design makes it exceptionally durable and resistant to shock and vibration.

Electrical Characteristics

The 2051-16-3 connector features a current rating of 3A, a voltage rating of 100V, and a maximum insulation resistance greater than 1000 megaohms. Additionally, it is designed with a contact-to-contact resistance of less than 10 milliohms and an insulation resistance of greater than 5 gigaohms. The contact material is gold plated with silver/nickel undercoat, which is corrosion-resistant and high-reliability. The contact pins feature a locking mechanism that ensures secure latching with a maximum contact force of 16 pounds. The contact pins are designed with a maximum torsion force of 100 cycles to ensure durability and reliable operation.

Working Principle

Backplane connectors, such as the 2051-16-3, are designed to provide maximum system reliability. The contacts are designed in a two-piece configuration, consisting of a male and female contact. The terminals are securely locked in place by an interlocking mechanism, ensuring that the contacts are secure and the circuit is correctly closed. The contacts are designed to have an extremely low resistance, providing steady current and power transmission. The contact force is designed to achieve maximum electrical performance and mechanical strength. Additionally, the contacts feature a locking mechanism to prevent loss of contact.

Conclusion

The 2051-16-3 Backplane Connector is designed for reliable performance in tough environments. Its heavy-duty plastic housing incorporates two-piece terminal contacts, each consisting of four gold-plated contacts. Its two-piece design makes it especially durable and resistant to shock and vibration. Additionally, it is designed with a locking mechanism to ensure secure latching with a maximum contact force of 16 pounds. Overall, the 2051-16-3 Backplane Connector is an excellent choice for high-reliability backplane connection applications.
