D-Sub Connectors

D-sub connectors are miniature connectors commonly used on electronic and instrumentation equipment. They are ubiquitous due to their versatility, robustness and generally long life. The connector system typically has a field-replaceable insert which grounds the pins within the subminiature connector, grouping and sustaining the pins during high-vibration applications. The 747461-3 is a popular D-sub connector model from one industry-leading manufacturer.

747461-3 Application Field

The 747461-3 is often used within the instrumentation, automation and laboratory equipment markets. They are popular where the components must maintain robust performance at all times and during testing or experimentation when vibration is expected. The design stands out because of its proven durability, the high quality materials used and the efficient wire management.

747461-3 Working Principle

The working principle of the 747461-3 D-sub connector takes advantage of specialized contacts inside the subminiature connector body. The contact points made by the pins protrude through the base of the connector, making contact with the metal insert. The metal insert is surrounded by a plastic insulator, but is capable of grounding the pins inside the body to create an efficient and reliable connection. The connector also features wire management, which helps to keep the connections tidy and reliable, improving the connectors overall performance.

The contacts are designed to make contact with the ground, but also to create a ‘land’ around the pins. This helps to boost the stability of the connection, allowing it to remain reliable during operations when a component may be subject to a heavy vibration environment.

Conclusion

The 747461-3 is a popular D-sub connector model commonly used in instrumentation, automation and laboratory equipment. It is renowned for its robustness and versatility and provides reliable performance in a variety of applications. It benefits from a field-replaceable insert which grounds the pins within the subminiature connector, creating an efficient connection with a ‘land’ for added stability. The connector also offers wire management for a tidier, more reliable connection.
