D-Sub Connectors are a style of connector often used for RS-232, RS-423, or parallel port connectivity. They are characterized by their D-shaped shell, typically with 3-15 pins, with the shell diameter being larger than its inside depth. The 749806-1 is a high performance connector with multiple features and applications.

The 749806-1 uses a shell in the typical D-shaped style, but with an extended length of 1.875”. This extended length allows for more pins, and improves isolation due to the increased surface area. This shell provides greater circuit protection and strain relief, preventing damage to the connector and its leads. The 749806-1 also boasts shorter lead lengths for greater space savings within the application.

The 749806-1 is a blind-mate connector, meaning that the connector can be mated without having to be physically present in the device or PCB. This makes the 749806-1 ideal for applications where space is limited, as the blind-mating allows for faster assembly. The 749806-1 is rated for 1000 mating cycles, and uses board-in contacts for increased performance.

The 749806-1 is an adapter and card-edge connector that is designed for Ethernet, telecommunications, and other high-performance applications. It operates up to 1GHz, with a frequency bandwidth of up to 400MHz. The 749806-1 also provides excellent signal integrity with both differential pair and single-ended signals. The contact-locking design ensures secure connections, and prevents connector separation due to shock or vibration.

The working principle of the 749806-1 is that it uses a contact force to provide secure and reliable connections. The contact force is generated by the contact-locking design, which helps to ensure secure connections and prevents the connector from being accidentally disconnected. The contact force also helps maintain a consistent connection throughout the life of the connector, even in applications where the connector is exposed to shock or vibration.

The 749806-1 is ideal for use in Ethernet, telecommunications, and other high-performance applications. The contact force ensures secure connections that resist shock or vibration, while the shorter lead lengths allow for maximum space savings within the application. The blind-mate design also allows for faster assembly, making the 749806-1 a great choice for applications where time and space are important.
