Industrial Circular Connectors are heavy-duty connectors that are typically used in tough environments and feature multiple contacts housed in a circular body. Circular industrial connectors can be used in automating processes and industrial applications. 

Some of our range boast high IP ratings such as IP67, IP68 and IP69K, making them brilliant to design into a high moisture environment. Circular connectors for industrial and automation applications are multi-pin connectors that are typically based in a plastic or metal housing.

Our range of Industrial Circular Connectors can be easily mounted via panel or PCB to get your project running. Typically our connectors come pre-built, however, we do offer a range that needs to be crimped and built. and are available in both plugs and socket types with straight or right angle cable entry.
