Rectangular Cable Assemblies

Rectangular cable assemblies, such as SFSD-05-28-F-08.00-DL-NUS, are specialized devices for applications involving wiring between electronic components or subsystems. Such assemblies can provide flexibility and ease of installation in applications where direct wire to component connections may be impractical to implement. Additionally, rectangular cable assemblies can provide noise immunity and enhanced reliability while improving user safety.

Uses

Rectangular cable assemblies are used in a number of applications, including networking, safety, instrumentation, medical, and industrial automation. They are also often used in low-voltage, non-process control applications because of their ability to deliver power and data in a lightweight and compact design.

Construction

The construction of a rectangular cable assembly is generally simple and consistent. The core of the assembly consists of two subassemblies, a plug and a receptacle. Each subassembly contains contacts made from metal such as oxygen-free copper, nickel-plated brass, or phosphor bronze. Each contact is crimped, assembled, insulated, and then either soldered or glued to form the connector. The cables used can be either single-cored or multi-cored, depending on the application.

Working Principle

The working principle of a rectangular cable assembly is based on the electrical connection between the contacts in the plug and receptacle. When the two subassemblies are plugged into one another, the electrical connection is made between the contacts, allowing power and data signal to flow between them. Typically, the two plug and receptacle subassembles need to be matched for cable specifications and assembly requirements in order for the connection to be made successfully.

Design Considerations

When designing a rectangular cable assembly, it is important to keep in mind the application and the environment in which the assembly will be used. Depending on the application, the cables used will need to have superior electrical characteristics and possess the necessary mechanical strength. Additionally, the contacts and insulation material used should be of such quality that will withstand the environmental conditions in which the assembly will be exposed to, including temperature, humidity, vibration, and corrosion.

Industry Standards

Industry standards for rectangular cable assemblies have been developed by the Institute of Electronic and Electrical Engineers and Underwriters Laboratories. These standards ensure that cables and associated components meet certain safety requirements and design criteria for use in electrical applications. These standards cover areas such as insulation requirements, operational tests, conductor requirements, connector design, and terminal marking.

Conclusion

Rectangular cable assemblies, such as SFSD-05-28-F-08.00-DL-NUS, are specialized devices for applications involving wiring between electronic components or subsystems. Such assemblies can provide flexibility and ease of installation in applications where direct wire connections may be impractical to implement. Designers must be aware of important considerations when specifying a rectangular cable assembly, such as cable specifications, mechanical and electrical characteristics, and industry standards.
