When you are working with multiple electronic systems, you will likely need a connector part to route power and signals across various applications. Across a myriad of industries, including those operating with aircraft, industrial machines, communications, and more, electrical connectors are needed to join printed circuit boards (PCBs) and modules as a last step during assembly, as this allows for separate circuits to be tested on their own, saving manufacturing time and costs. Many connector types also work as the interface between sensitive electronic equipment and the outside world. With many applications for electrical connectors, different variations are available to accommodate particular connections. As a popular choice for harsh environments, this blog will specifically take a closer look at metric circular connectors, their benefits, and their applications.
