Certifications for NEMA/IP Electronic Enclosures can make a Difference

An industry leader in electronic enclosures
Josiah Haas provides guidance on NEMA and IP rated enclosures

While I often use my blog to discuss important issues in enclosures or the electronics industry, it is sometimes nice to hear a different voice in the process.  Josiah Haas, our president, was recently interviewed for Automation World by David Greenfield on the differences between a certified and non-certified enclosure and when to use what type of certification. He clarifies how the use of the appropriately rated products can improve both uptime and component safety.  As companies move their products into different environments and/or upgrade their current products, this podcast is a solid background to insure that the engineer is making the right choices.   Here is the podcast link:

Bud Industries 4th of July Musings

NEMA Box
Bud has a complete line of NEMA IP electronic enclosures

As I write this and we prepare for the 4th of July holiday, I am once again struck by the American Dream and how our Electronic Enclosure Company’s story could have only happened in the United States.  As I have mentioned before, Bud Industries was founded as Bud Radio by my grandfather, Max Haas, in 1928.  An immigrant from what is now the Czech Republic around 1900, he had a self-taught engineering and marketing mind and was fascinated by what we would now call technology and the opportunities it would present.  What started as an antenna company (the first to offer a product that eliminated the need for a roof top radio antenna), evolved into car antennas, and then into other radio parts (he sold off the antenna business), and finally into enclosures.  He and my grandmother worked hard to take the ideas he uncovered and turn them into a solid enduring business. 

I think about how few countries, at that time, would allow a refugee family to be welcomed into their land, provide free education for their children, and encourage them to be whatever they wanted with relatively limited restrictions.  While America of that era was not perfect, it offered many the chance to create the best life they could for themselves and their families and to hopefully allow their children to have better lives than theirs.

Fiberglass Electronic Enclosures Broaden their Appeal

Although I have been involved with the electronic enclosure industry for nearly 40 years, I continue to be amazed at the variety of applications which require these enclosures.  The application space has expanded significantly since we introduced NEMA 4x Fiberglass Enclosures a few years ago.  These durable boxes are priced well below market, but provide industry leading protection.    They are more durable than polycarbonate boxes with less vulnerability to cracking when struck.   Some of the applications that we have seen recently include:

  1. In solid state lighting, the controls for the lighting need to be enclosed and often protected from outdoor or factory environments.  Numerous customers find that fiberglass provides a simple solution to long term exposure
  2. Fiber optic distribution, again in the lighting or energy fields
  3. In food services, we have customers that locate their controls in the fields or barns to track production where frequent hose down or weather situations require proper protection
  4. Climate controls and environmental tracking industries are also a unique niche that fiberglass enclosures effectively support.
  5. Solar Energy collection and conversion is a growing application for these electronic enclosures as they can withstand higher heat and yet are not conductive as one finds with metal enclosures.

The market for Fiberglass enclosures is broad and rapidly growing as pricing becomes more competitive.  With durable protection, limited conductivity, and hose down capabilities, they have much to offer.  Don’t forget that we can modify these boxes with cutouts, slots and other secondary operations to improve assembly time and truly provide a turn-key solution.

Enclosures that Offer Great Value

When selecting an enclosure, often an engineer is focused on the aesthetics of the box, looking to the “shell” to help create an attractive device to promote in the market.  This is especially true in a consumer type product where marketing is as important as design features.  But there are many instances where all that is required is a strong enclosure to provide protection for the sensitive equipment inside.  For a smaller box, one of the most cost effective yet durable solutions is a die cast aluminum enclosure.  Die casting is a low cost operation that produces a product that provides a large level of protection from external damage, yet often comes with great features such as molded in pcb mounting slots and offsets.  The come in versions that include NEMA or watertight enclosure gasket or even protection against EMI/RFI.  While they are tough, they are relatively easy to modify for holes, cutouts or even powdered or silk screened.  Bud offers all of these versions plus options for welded or molded mounting brackets.  For many, it becomes important not to just look at the visuals, but to evaluate all of the electronic enclosure options to determine the best overall value to the project.

How to Interpret NEMA Ratings

Perhaps one of the most confusing standards for an engineer to follow is NEMA ratings as it relates to enclosures.  It would be natural to consider that the higher the NEMA rating, the greater the protection.  This is definitely not the case.  It is also typical that one might assume that having a NEMA rating of any sort implies a high level of protection.  This is also not the case.  NEMA ratings are set up in a way to address a variety of concerns:  safety from moving parts, protection from dripping water, dripping oils, sprayed liquids, UV, corrosion, ice, and many more.  NEMA 1 ratings, for example, simply suggest that the product protects against contact with moving internal parts.  The ratings becomes confusing when you consider that NEMA 4 protects your product from sprayed water, ideal for wash-down or weather intensive locations.  NEMA 12 only protects against dust, falling dirt and dripping liquids so would be more appropriate in an environment where there may be less significant environmental factors, such as a factory which may not be a clean room.  NEMA 3 is weather resistant, with NEMA 3r protecting against icing as well.  The point is that you want to be sure you are receiving the level of protection you need without overpaying for too much.  For a complete listing of all of the relevant NEMA ratings for enclosures, Bud has a great tool, the Design Tips Handbook which you can download for free at http://www.budind.com/request_designtips.php .  Good luck with your design!

Electronic Enclosures Musings

This is the first real posting on the new Bud Industries Blog.  Why have I decided to start a blog?  Does the world really need one more?  I think it does and there are several good reasons why.  First, any good engineer focuses their energy on designing the components that go into the box, and frankly have limited time to learn the choices in enclosures.  I will chat about the best ways to select the perfect enclosure for any application.  For example, determining which NEMA rating is required for an application can be confusing, yet the right choice will save money and insure the integrity of the finished product.  Another question I will cover is the proper materials required for the enclosure.  Often, the designer is most comfortable with a material they have worked with before, but my posts will help them understand where alternatives may provide improved flexibility or functionality.  Our mission is to make specifying the least technical component, the enclosure, quick and easy.  So check back often, let me know if there are areas that you would like me to discuss, and I hope you enjoy the blog.
