Circular Connectors from Northern Connectors
If you’re searching for a high-performance terminal to connect cables in a site that may involve high pressures, vibrations, temperature shocks, or similar kinds of mechanical turbulence, then look no further than our circular connectors. The same applies if you need industrial cable connectors that are protected against interference from electromagnetic signals.
Of course, these high levels of protection also enable our extremely resilient circular connectors to withstand moisture and water, dirt and dust, and other particles that may otherwise get inside and potentially damage the cables within the connector.
We have a large selection of circular connectors available with next-day delivery, with a variety of IP ratings and mating styles, as well as miniature and sub-miniature versions. Whether you need snap-in or push-pull connectors, sew termination, bayonet connectors, panel-mounted or board-mounted connectors, you’re sure to find exactly what functionality you need for your project.
We also supply hybrid circular connectors, which conveniently connect both power circuits and signal circuits using a single shell.
What are the benefits of circular connectors?
Circular connectors have become widely adopted across a range of industries due to their robust design, ease of use, broad range of configurations and extreme versatility. Consisting of multi-pin inserts sat within a robust mechanical housing with a circular design, they are capable of efficiently transmitting data, signal and power.
These versatility of circular connectors and their broad range of benefits and useful attributes have helped them become an indispensable industry standard:
- Easy to install and remove
- Compact designs
- Reliable and secure locking mechanisms
- Sealed ingress protection up to IP68 & IP69K
- Capable of housing various kinds of contact within the same shell

Frequently Asked Questions
What are circular connectors?
Also known as ‘circular interconnects’, circular connectors are essentially what their name suggests – cylindrical mechanical shells used to connect cables in the form of multi-pin connectors. They ensure that data and power can be continuously transmitted safely between devices.
Circular connectors have been manufactured and implemented to deliver vital electrical signals that keep complicated systems and machinery running as they should, especially in demanding environments where their hardwearing design offers essential protection.
The cylindrical design of circular connectors allows them to reliably deliver a continuous stream of data and power without the cables becoming misaligned and accidentally decoupling, or being damaged by surrounding elements.
The contacts of a circular connector are typically made from oxygen-resistant metals like steel or brass, which can also be plated with another metal to improve their electrical conductivity, while the shell that houses and seals is often made from a resilient insulating material like moulded plastic or rubber.
