Backplane Connectors - Specialized - 51939-185 Application Field and Working Principle

The 51939-185 is a specialized backplane connector that has become essential for many industrial applications. The connector has been designed to quickly and easily connect a number of electrical and electromechanical components. It is widely used in industrial control, telecommunications, aerospace, and medical electronics and has been adopted as a standard by many manufacturers.

Functionality and Specifications

The 51939-185 connectors have a modular design and are available in two types: single-row and double-row. They have a low-profile with a uniform thickness that provides good wear resistance. The contact features of the 51939-185 connectors are gold plated with a round pin and square socket design, which minimizes impedance and eliminates resonance in signal transmission. The adapter also has a highly reliable locking system that provides good tensile force and minimized crosstalk.

Application Field

The 51939-185 connector is an ideal choice for a variety of industrial applications. Its gold plated contact features provide a high-speed, low-resistance connection with minimal crosstalk. The adapter is also ideal for applications that require frequent changes in voltage and current, as the durability of the connectors ensures that it can tolerate a wide range of temperatures. It is commonly used in industrial control applications such as data acquisition, relay logic control, motion control systems, machine automation, and process control.The connector is also suitable for telecommunications, aerospace, and medical electronics. It is often used in high-speed communication systems such as Gigabit Ethernet, 10 Gigabit Ethernet, and Fibre Channel. Its reliable locking system ensures a secure connection and minimal interference in signal transfer. In aerospace, the 51939-185 connector is used in air traffic control systems, data link communication, and navigation systems. In medical electronics, it is used in medical imaging equipment, patient monitoring systems, and other medical device applications.

Working Principle

The 51939-185 connector is designed for easy assembly and disassembly. The two halves of the connector are connected by a movable section. The two halves have a unique ‘contact-controlled’ locking system that prevents the connector halves from separating. To connect the halves, the movable section is pulled back, allowing the connector halves to slide together. Once the halves are connected, the movable section is released, creating a secure connection between the components.The 51939-185 connector provides reliable, high-speed connections with minimal crosstalk. The gold plated contact features ensure that signal transmission is precise and interference is minimized. The adapter is also highly durable and can withstand a wide range of temperatures.

Conclusion

The 51939-185 backplane connector is an essential component for industrial, telecommunications, aerospace, and medical electronics applications. Its reliable connections with minimal crosstalk, high-speed signal transmission, and durable design make it an ideal choice for a wide variety of applications. It is also easy to assemble and disassemble, making it an ideal choice for applications that require frequent changes in voltage and current.
