Frequently asked questions

What are power connectors?

Power connectors are used to connect power sources to electronic devices, transferring electrical power from one point to another – whether between different devices or within the same unit. They can also be used to transfer data at the same time. 

Industrial environments demand a consistent supply of high levels of power, so heavy-duty industrial power connectors are needed to create and maintain stable electrical connections that can handle these more intensive requirements. 

Industrial power connectors come with a range of current rating and voltage options, as well as a variety of termination styles and locking mechanisms to ensure a strong and stable connection. There are several ways they can be securely mounted to enhance safety and prevent accidental disconnection. 

Power connectors may be easy to assemble and link together for efficiency, but they are constructed with hardwearing housings designed to protect against all kinds of challenging conditions experienced in industrial environments. This includes everything from dustproofing and waterproofing to resistance from high temperatures and pressure. 

What types of power connectors are available?

We supply high-quality power connectors suitable for a range of industrial applications here at Northern Connectors. As you will see from browsing above, our selection includes industry standard IEC/EN 60309-1 & IEC/EN 60309-2 connectivity, power/signal hybrid solutions, modular configurations, and more.

Industrial power connectors are available in the form of circular connectors, rectangular connectors, and D-sub connectors, each with a variety of pin configurations, shell sizes, and orientations. These rugged connectors also have various housings and hoods available in lightweight plastics, which can offer ingress protection of IP67 and above when mated.

When you click on a product type for more information, you can view the specifications and any special features available that may make the connector more suitable for certain applications. We provide the manufacturer's brochure as a downloadable PDF so you can read through every detail for yourself and find out which other products and accessories are compatible with your equipment.

Which power cable connector do I need?

With so many power connectors and associated components to choose from, if you don't already have a specific product in mind, then you may not know where to start in selecting the most suitable power connector for your intended application.

To make this process more efficient and convenient, the Northern Connectors website allows you to browse by industry, so you can narrow down your search to connectors that are designed for use in your sector – whether that's automation, instrumentation, transportation, or another. We also have several connector guides available as downloadable PDFs.

As suppliers of industry-leading connector brands, you can also browse by brand if you prefer to use products from a specific manufacturer. Or, if you're looking for reliable connectors that can withstand dust and liquid ingress, you can also browse by IP rating.

If you're searching for replacement or compatible parts, you can simply contact us with the individual numbers marked on each part, and we can then help you source the exact power connector parts you're looking for. Even if you're starting from the ground up with a new design, you can always come to the knowledgeable Northern Connectors team for technical advice.
