D-Sub, D-Shaped Connectors - Backshells, Hoods - are a type of connector widely used in modern computer systems and other devices. The 5749190-1, in particular, is an specialty connector used for various applications. This article will discuss the application field and working principle of the 5749190-1.

Application Field

The 5749190-1 D-Sub connector is a high reliability solution for those applications where EMI/RFI shielding is a priority. It is suitable for applications in military, aerospace, and other harsh environment such as shipbuilding, factory automation, and medical applications due to its high degree of reliability. It is also widely used in the automotive sector due to its vibration and shock resistance. In addition, this connector is also suitable for applications in the telecommunications sector due to its low maintenance requirements and its high level of RFI protection.

Working Principle

The 5749190-1 utilizes a specialized type of electrical connection called a ‘floating ground’ in order to improve the EMI/RFI shielding. Floating grounds allow the current to flow between the inner and outer wire shields while maintaining the electrical and electromagnetic isolation between the two shields. This ensures that the signal is protected from outside interference.

The 5749190-1 utilizes a one-piece design with two-part housing, which provides a good balance between shielding and accessibility. This design allows for easy installation and maintenance. The connector’s pins are tensioned, ensuring greater reliability and providing a secure connection. The two-part housing also has the added advantage of helping to minimize undesired noise within the circuit.

The 5749190-1 is constructed from top-grade materials that have been specially selected and processed for use in a harsh environment. The metal housing is nickel plated to provide additional protection against corrosion. The insulation material and the contact design are optimized for this particular application, providing superior EMI/RFI protection and higher reliability. The contact pins are plated with tin-nickel to ensure good electrical performance and improve the signal transmission.

The 5749190-1 is a reliable, high performance connector and is ideal for a variety of applications. Its combination of excellent contact design, top-grade materials, and effective EMI/RFI shielding make it a great choice for harsh environments. It provides superior performance both electrically and electromagnetically and is sure to meet the demands of any application.
