All About Circular Connectors
The choice of which connector to use for operations in need of data and power transfer can be challenging. Of the two basic design choices, rectangular or circular, both offer wide ranges of versatility and many benefits across various applications. Both circular and rectangular connectors can be custom ordered and specified for the number of contacts, contact diameter, shell size, configurations, and more. However, circular connectors boast unique advantages over rectangular connectors for specific applications and environments, those of which we will cover in the following blog.
Commonly used for free-hanging connections, circular connectors are easier to mount on a panel compared to rectangular connectors, for starters. As there is a wide selection of circular connector designs available today, the method used to fasten them to your applications can vary, offering designs with threaded, bayonet, or snap-lock fasteners. It is often wrongly assumed that circular connectors are not well-suited for applications where space is limited, but the wide variety of circular connectors available today includes miniature designs for such uses. In addition to their versatility, circular connectors surpass rectangular connectors as the best choice for a few key advantages.
Interestingly, circular connectors are ideal for extreme environments, as they are constructed to be more durable than their rectangular counterparts. Circular connectors boast rugged construction, such as designs that feature a closed-entry female contact design with secure threaded or push-pull coupling options. These design options prevent contamination or wear caused by water or dust, while maintaining a secure seal in extreme environmental conditions. As such, for applications that must receive an IP-67 rating or higher for ingress protection, circular connectors are the best option. Circular connectors are also ideal for applications that must meet the compliance requirements set forth by IEC and RoHS. Overall, circular connectors perform better in harsh and corrosive environments due to their rugged design.
Due to their many strengths, circular connectors are often used in military applications, medical settings, automotive manufacturing, and other types of machine building. Circular connectors are also wise choices for conditions exposed to oil and gas. When you know your application requires a circular connector, you should consider three main factors prior to procurement. First, consider the proper wire gauge for your applications to ensure all parts of your application fit together. Next, you should consider the amperage of the devices with which your connector will be paired. Lastly, you should consider the environment of your devices, and for any further guidance, it is always wise to seek guidance from a professional. With many connectors to choose from for your power and data, the task of selecting the right design can be daunting; however, with the right information, you can locate a connector that will keep your devices operating steadily.
