D-sub connectors are a type of electrical connector used in a variety of applications. Also known as DB connectors, they are named for their distinctive D-shaped shell and typically used for low-voltage signals. D-sub connectors can be further broken down into size categories, based on the number of pins they contain, and each size offers a different level of performance and capability, including shielding for protection against electromagnetic interference.

The 1655409 D-sub connector is a high-density, mini-D connector that is designed for use with rigid flex circuits. The connector features nine positions and performs both power and signal functions. The contacts are 24-28AWG, and the shell is made from diecast aluminum. It is designed to fit into a .100 inch (2.54mm) pitch, and the holding force of each pin is rated at 5 pounds (2.2kg). The 1655409 also meets flame-retardant requirements UL 94 V-0.

In terms of application, this particular D-sub connector is well suited for use in flight control, position control, and computation systems, as well as hand-held communication systems. Thanks to its high-density construction, it is able to handle a large number of interconnects in a small form factor. This makes it suitable for applications such as transportation, medical, and military.

In terms of working principle, the 1655409 D-sub connector features a carefully designed spring-loaded connection system. This ensures a secure connection between the cable and the connector while preventing any undesired disconnection due to shock or vibration. The connector is held in place by either a plastic latch or a metal latch, depending on the application, and the pins are configured in a solder bucket to streamline the soldering process.

Overall, the 1655409 D-sub connector offers a reliable and cost-effective way to connectivity in a variety of applications. Its high-density and flame-retardant design makes it suitable for use in applications such as aviation, transportation, medical, and military, while its spring-loaded connection system ensures a secure connection that will last for years.
