Choosing the right connectors for industrial automation applications can pose a lot of challenges. Automated systems form the backbone of many modern sectors, and as such, they require components and connectors that meet the highest standards of quality and reliability.

When selecting a connector for your automation application, it is therefore important to ask yourself the right questions. Will this component be suitable for the demands of the working environment? Can it be relied upon to deliver long-lasting performance, without requiring maintenance? Can it be incorporated into an efficiently-designed system?

To help you find the right connector for automated systems, Northern Connectors has teamed up with HUMMEL, one of the world’s leading manufacturers of industrial connectors, to offer advice on how to choose the best components for your application.

What should I look for in a connector for automation?

Choosing the right connector for automation industry applications means looking for products that offer guaranteed performance on a number of important metrics. Here are the key qualities to look out for, as recommended by the experts at Northern Connectors and HUMMEL:

High transmission capabilities

Connectors used in automation applications are required to support the effective transmission of power, signals and data via industrial ethernet. In this Industry 4.0 era, these demands are only increasing, as modern innovations emerge that require enhanced networking, intelligent controllers and lightning-fast communication between machines and products.

As such, you will need to ensure that your connectors are able to provide a robust performance in terms of transmission capability, delivering the speed, voltage and/or power needed to keep your systems operating at peak performance.

Robustness and reliability

Automation technology is used in a wide variety of sectors and environmental conditions, from outdoor environments where equipment is likely to be exposed to the elements, to challenging industrial settings where ambient temperatures can run higher than 100°C.

If you require a connector for an automation application, you will need to realistically evaluate all of the conditions under which your systems will operate, and find a connector that is able to provide a firm, reliable and secure connection even under duress.

Compact design for space-saving

Because automated equipment is designed to operate independently, without relying on manual maintenance or interaction, these systems need to be designed as efficiently as possible to accommodate all of the circuitry and components needed for self-sufficient operation.

Space is often at a premium when designing a system that provides reliable automated functionality, which is why it is important to look for connectors with a compact design that can fit comfortably into an efficient layout.

Hybrid connector design

Another means of conserving space within an automated equipment layout is to utilise connectors that can serve multiple purposes all in one shell, with a single connector taking the place of two or more single-purpose components.

Many modern hybrid connectors are able to achieve this, transmitting power, data and signals through the same cable in order to provide considerable savings on space, costs and setup time.

Which HUMMEL connectors are best for automation applications?

If you are looking for connectors for an automation application that tick these boxes, HUMMEL can recommend a number of industry-leading solutions that have been proven to offer significant advantages and reliable performance:
