There are many Types of DIN rail enclosures. DIN rail Enclosures are produced in different sizes, colors, shapes, heights, etc. depending on the industry they are manufactured to. For instance in the Building automation industry DIN 43880 is the most common DIN rail, as it fits the electrical cabinet in regular housings and buildings. In the process manufacturing industry however the DIN IEC 60664 is the most common DIN rail, as it is larger and fits larger electrical cabinets that are used in accommodating a large building height.
In the Machine industry they use a mix of both DIN rails depending on the specific case. The DIN rail enclosures are manufactured to fit the DIN Rail, so when the DIN standard that is best for your application is decided, you can find the size of the DIN rail enclosure for the exact need. The width of the enclosures are mainly from 1 module to 15 modules which is 17,5mm up to 262mm.
When working with electronic installations, especially in industrial control, automation and networking applications, you will undoubtedly come across the DIN rail in your journey. These rails are the metal rails used to mount electronic components in control cabinets, junction boxes or electronic enclosures. You can think of them as the backbone of complex electronic setups, as they are the components that house circuit breakers, contactors, terminal blocks, transformers, relays and other control equipment to the rack within a cabinet.
The fact that DIN rails are made to an industry standard, which is now adopted globally, allows them to be compatible with many different electronic components. As such, you can be sure that your DIN rail's terminal blocks or circuit breakers will fit regardless of the manufacturer. This standard also allows us to produce DIN rail enclosures that are compatible with the rails you already own or plan to use in your next project.
We recommend implementing these kinds of mounting rails and enclosures in any environment where you don't want to fuss with panel mounting, or for applications such as control panels when you want a central location for all of your equipment. What's more, DIN rails can help you save space while also reducing labor time and cost, as they allow engineers to easily and quickly attach interchangeable components to the rail. At a glance, these rails simplify and standardize setups so that you can effortlessly work with parts and products from many different manufacturers.
While a good majority of DIN rail jobs are hyper-specific to the user, there are some basics that apply to most projects to help you get started. We will also help you determine which type of enclosure is appropriate for your unique DIN rail needs, as you should be well aware of materials and how they perform in certain environments.
How to Choose Din Rail Enclosure for Your PCB?
Consider the Requirements
Before you choose a DIN electrical box, determine your needs. You should go with an enclosure that's right for your applications. That will help you decide which material is a good fit. For instance, while there are plastic enclosures, an aluminum enclosure might be best for you.
Start with Popular Options
When you shop for a DIN rail enclosure, exploring popular options tells you about the latest trends and designs in the industry. It gives you a solid idea about what other consumers buy. If you've always gone for a specific type of enclosure, going over popular options updates you on the latest market offerings. There could be better choices that you can choose from. That's why it's an excellent idea to always check which enclosures are popular.
Look at Size
You can choose a DIN rail box from a wide array of colors, sizes, and orientations. Browse through the many styles available. If your PCB sits in the box or enclosure, you should go for vertical sizes at around 7.5 mm up to 45 mm. If you're checking out horizontal dimensions, you should look for options ranging from 18 mm in width to about 270 mm.
Check the Features
Features can make a huge difference when you shop for a box for your PCBs. Standard enclosures come with vents, pre-loaded terminal blocks, and led holes. You can also expect removable sides and covers and clear plastic faceplates. If you need multiple board applications, check if the enclosure comes with other profiles.
Go Over Specification
Before you choose an din rail enclosure, consider the specification of the box. Check its approval rating. Do those details check out? If you have modifications, consider looking for a manufacturer that provides custom din rail enclosures. That will make it easier for you to select the din rail enclosure you need for your PCBs. With customized features, you won't have a problem finding what you're looking for.
Research the Manufacturer
What do you know about the manufacturer? Is it easy to get in touch with them? Choose a vendor that you can work with easily. Find one that's responsive to your inquiries, calls, and emails. Prompt replies are good. That means they're interested. If the company takes days or even a week before they answer, bring your business elsewhere. Check if there are any official complaints lodged against the company. That could mean recurring problems with the company's services or products. Spare yourself the stress and choose a different manufacturer.
