Q-G® PD Series, Circular Connector Assemblies

Circular connectors, also known as circular interconnects, are a type of electrical connector designed in a circular form factor with multiple pins or sockets. These connectors are characterized by several key features, including the connector type, number of positions, shell size-insert, shell size MIL, mounting type, and fastening type. Connector type refers to the specific function or application of the connector, and includes options such as distributor, h-distributor, insert, jack and plug, line drain, line source, panel drain, panel feed-through, plug and receptacle, plug, receptacle, t-distributor, and terminal outlet. The number of positions refers to the number of pins or sockets in the connector, which can range from just a few to dozens or even hundreds. Shell size-insert and shell size MIL refer to the physical dimensions of the connector, with shell size-insert denoting the size of the connector in millimeters and shell size MIL referring to the size in inches. Mounting type refers to how the connector is attached or mounted, with options including free-hanging, panel mount, and PCB mount. Finally, fastening type refers to how the connector is secured or fastened, with options including bayonet, screw, and push-pull mechanisms. Overall, circular connectors are versatile and widely used in a variety of applications, from aerospace and defense to automotive and industrial systems. Understanding the various characteristics and options available for these connectors is essential for selecting the right type for a given application.
