Introduction

D-Sub Connectors are a type of electrical connectors that are typically used for data and serial connections. The 179-025-613R491 is a specific type of D-Sub Connector. It is a relatively small connector that is used in a variety of applications including telecommunications, medical, communications, and automotive. The 179-025-613R491 can also be used in industrial automation systems. This connector is made up of several individual components that work together to create the complete connector.

Design

The 179-025-613R491 D-Sub Connector is made up of metal contacts, an inner insulator, a flame-retardant shell, and a crimp band. The inner insulator is made of high-grade PBT material that is flame-retardant and corrosion resistant and has a high mechanical strength. The metal contacts are made of zinc alloy and are plated with either a gold or silver finish depending on the application. The crimp band is made of stainless steel and is designed to securely attach the contacts to the inner insulator. The flame-retardant shell protects the internal components from external damage and is also designed to provide an electrical connection between the contacts and the crimp band.

Application Field

As mentioned, the 179-025-613R491 D-Sub Connector has a wide range of applications. In telecommunications, the connector is used to connect telephone lines and digital transmission lines. In medical and communications applications, the connector is used for on-board diagnostics. This connector is also used in industrial automation systems for sensor and actuator connections and in automotive applications for controlling audio signals.

Working Principle

The 179-025-613R491 D-Sub Connector works by providing an electrical connection between two different components. The metal contacts are inserted into the inner insulator, and the crimp band is attached to the contacts. This creates an electrical connection between the contacts and the inner insulator. The inner insulator and the contacts are then securely held in place by the flame-retardant shell, which also provides the necessary electrical connection between the contacts and the crimp band. The electrical connection is then completed by attaching the two connectors to the respective components. Once the connection is established, data or signals can be transferred between the two components through the D-Sub Connector.

Conclusion

The 179-025-613R491 is a D-Sub Connector that is used in a wide range of applications. It is designed with a metal contact and an inner insulator, which are held in place by a flame-retardant shell and a crimp band. The connector works by providing an electrical connection between two components, allowing for the transfer of data or signals. It is reliable and durable, making it suitable for a variety of applications.
