Industrial connectors are specialised cable connectors that are used to secure cable assemblies in industrial environments, ensuring stable connections for efficient power, signal, or data transmission.
Unlike standard connectors, industrial-grade cable connectors are specially designed to endure challenging industrial conditions – such as vibrations, moisture, and high temperatures.
These connectors are available in a wide variety of sizes, shapes, and configurations to meet the specifications required for industrial applications across diverse sectors.
Their importance cannot be overstated, but for those new to the world of industrial connectors, the vast choice might seem confusing or overwhelming.
That’s where this beginner’s guide can help – read on to learn more about industrial connector types, applications, and requirements, and where to find them.
Types of industrial connectors
The most common types of industrial connectors that you’re likely to come across include:
- Circular connectors – featuring cylindrical housing for compact multi-contact connections
- Rectangular connectors – space-saving rectangular housing for higher contact densities
- D-sub connectors – forms a ‘D’ shape that facilitates straightforward and stable insertion
- Coaxial connectors – aka RF connectors, which transmit multi-MHz radio frequencies
- Ethernet connectors – aka RJ45 connectors, which provide fast data transmission
Circular, rectangular, and D-sub connectors are typically power connectors, but – depending on the design – they can often accommodate multiple types of connections in the same shell.
Coaxial connectors transmit radio signals, while Ethernet connectors transmit data. All of these transmissions require rugged cable connectors that can withstand harsh conditions.
Industrial connector applications
Industrial processes heavily rely on the undisrupted transmission of power, signals, and/or data. If something goes wrong with a cable connection somewhere in the assembly, the whole system could be compromised, with potentially dangerous consequences.
For example, industrial connectors are used to run a wide range of machinery, from medical to telecommunications to aerospace equipment. Reliable computers, automation, and power distribution are critical to keep the world running as we know it.
Without robust connectors that can maintain transmissions between control systems and different devices in industrial settings, cables and connections would fail under conditions like constant exposure to heat, moisture, vibrations, and potential impacts.
After all, electrical and signal failures can pose severe safety risks, from fires to inoperative machinery – which is why industrial connectors have standardised qualities to prevent this.
Requirements for industrial connectors
It’s obvious, then, that industrial connectors must be carefully designed, tested, and implemented according to strictly regulated standards.
The first step in choosing an industrial connector that meets the precise requirements of a specific application is to determine the current, voltage, and frequency characteristics, plus the number of contacts and their layout.
Next, you should consider mechanical compatibility – the connector shapes, sizes, mating interfaces, mounting options, termination styles, and locking mechanisms will influence the success and stability of the connection.
Mismatching connectors will lead to installation and maintenance issues and result in poor connectivity, which is why it’s important to stick to the same connector types and/or brands throughout a system to ensure they’re compatible.
Another key step in ensuring optimal performance from industrial connectors is to select designs that have been tested to the environmental conditions you need them to operate in – not just the minimum, but the maximum levels.
This means looking into the capabilities of the housing and seal design as well as the IP rating. The latter explains the level of protection the connector has against the ingress of dust and moisture – some may also have ratings for temperature and chemical resistance.
Something that can help with all of these requirements is choosing products from reputable industry-leading brands, and ordering them from a trusted distributor.
Finding an industrial connector distributor
A reliable connector distributor will not only offer an extensive catalogue of industrial connector products, but will also have years of experience and insight to back up their services.
So, if you go to a long-standing UK distributor of industrial connectors, such as Northern Connectors in the North West, they can guide you through the suitable products they have available based on the requirements of your application.
Other than the manufacturer, there’s nobody who understands the industrial connectivity solutions they provide better than the supplier, so there’s no-one better to help you navigate the busy world of industrial connectors – ensuring you get what you need, when you need it.
