Circular metric connectors are an electrical connector type made according to a metric standard. This type of connector features circular metal shells with metal pins or terminals on the inside. These connectors are common in a variety of applications, ranging from test and measurement equipment to automotive connections.
The circular metal shells of these connectors are usually made of brass which offers high electrical and mechanical resistance. The interior of the shells includes several metal terminals which can be either male or female in design. The pins are typically made of copper, silver or gold depending on the application. Depending on the design, the terminals can be arranged in various ways such as break-away tabs, insulation displacement connectors (IDC) and other configurations. These configurations can help protect against electrical shorts and provide reliable connections.
Due to their standardized designs, these connectors are suitable for use in a variety of applications. They are used to provide connections between modular devices and for many industrial and automotive connectors. They are often used for power, signal, and control connections.
Overall, circular metric connectors are an extremely versatile type of connector that can be used in a variety of settings. They are reliable and provide a secure connection.
