D-Sub connectors are electrical connectors that have a manually operated, two-piece electrical mechanism used to connect and disconnect cables and wires. These connectors come with both male and female pins that are fitted into a single-piece shell. The male pins slide into the female sockets with the help of a sliding mechanism which gets actuated when the main pin is twisted. Generally, these connectors come in three varieties which are specified according to the pin configurations. The most commonly used variety is the 9-pin male and female varieties, which are usually used for connecting VGA, Ethernet and audio-visual equipment.

The 747459-5 D-Sub connector is part of the Amphenol D-Sub Connector series which comply with the US military specifications of environmental, mechanical and electrical requirements. The connectors belong to the 9-pin gender (shell) variety and feature two contact inserts with PCB mount directors. Structurally, it is made up of two parts: the main body and the shell that cover the male pins inside. The two contact inserts, which adhere to the pin size of 7.62/0.254mm and have a current rating of 3 A, connect the wires going in and out of the connector.

The body of the 747459-5 differs from typical D-Sub connectors in the way that it offers superior protection against dust, moisture and water ingress, which might be an issue when the connector is mounted in outdoor environments. The body is built with IP67 protection and also has a soldering/welding tail. This offers enhanced reliability and is usually seen in heavy-duty, industrial grade applications such as power plants, industrial manufacturing, and agricultural and transportation equipment.

The 747459-5 offers effective protection against short-circuits and leakages, thus providing greater safety and preventing the risk of electrical shocks or system failures. The contacts of these connectors are replaceable, and the connection is held firmly, offering a robust and secure connection which is ideal for a wide range of signal and power applications. The contact inserts have silver-plated copper alloy with gold overplating, offering repairability and increased service life. The connector also features a designed shield cover, which offers superior EMC shielding protection from electromagnetic and radio frequency interference.

The 747459-5 is available in different sizes and is suitable for many applications such as process control, medical equipment, drive control systems, instrumentation, telecommunications, and automotive applications. This connector comes with a wide range of features and specifications which make it suitable for use in difficult and challenging environments.
