D-Sub connectors are one of the most widely used interconnection systems in the world and are used in a variety of industries, from automotive and industrial, to consumer electronics and medical device applications. A D-sub connector is a type of electrical connector containing multiple parallel pathways of wires or cables housed in a metal shell. The D-sub terminals are contained within the housing, which acts as a shield against dust and other elements, preventing it from entering the connection and causing damage. The term “D-sub” comes from the «D» shaped metal shell which provides a housing for the terminals, and it also includes a type of backshell which surrounds the terminals and provides additional protection from the environment.

The 749854-1 application field and working principle is a D-shaped connector produced by Neutrik. This type of D-sub connector can be used in a variety of applications ranging from professional audio and video applications, to automotive and robotics. The 749854-1 is a male connector with two contact rows that mate with a female socket connector. This type of connector is suitable for industrial and automotive environments due to its robust design.

The 749854-1 connector is covered by a backshell and housing which provides extra environmental protection. The backshell is an important part of a D-sub connector, as it helps to keeps dirt, dust, and other contaminants away from the contact pins, preventing leakage and corrosion and extending the life of the connector. This backshell also provides strain relief for the cable and helps to reduce crosstalk between signals and ground lines.

The working principle of the 749854-1 D-sub connector is very simple. Two contact rows are inserted into the female socket connector and the backshell is then snapped around the two. The backshell provides extra protection and strain relief, and this is essential as it helps to prevent wear and tear from repeated use. The contact columns in the 749854-1 are held securely in place by a spring-loaded finger mechanism which helps to ensure proper alignment and eliminates unwanted movement. This ensures that the connector is secure and resistant to vibration and shocks.

Overall, the 749854-1 is a great option for applications where robust, reliable connectors are needed. The D-shaped connector provides a secure connection which is resistant to dust, moisture and vibration, and the backshell helps to keep out dust and contaminants to prevent wear and tear. The 749854-1 is a reliable connector which can be used in many applications, from industrial and automotive, to professional audio and video applications.
