Flammability 101 for Plastic Electronic Enclosures

Knockouts make it easy to install your equipment
Among the broad line of plastic products are various options for
flammability and IP/NEMA Ratings

We are often asked about our flammability ratings and what they mean.  Quite simply, they allow the designer to understand how the plastic material will act when exposed to fire and how it impacts that fire.  A key point is that the testing is done on a sample of the material, not on the final enclosure.  Further, it does not deal with how the box will protect the components but more how the material will react when exposed to a flame.  It assists in understanding how will the enclosure will protect against the fire or, potentially, if it will contribute to it. 

Here are the ratings that are most often developed for the materials that are used to make plastic electronic enclosures: Read More >>

Bud Industries introduces IP67 Vents

Bud's IPV IP67 Vents
Bud’s new IPV Series vents are rated IP67

One of the most significant problems in protecting electronic or electrical components with a NEMA/IP rated enclosure is ventilation.  By the nature of the enclosure being sealed, air flow or cooling is a challenge.  Further, as the components typically produce heat, there can be a heat buildup within the box creating not only high internal temperatures but also condensation as the internal and external temperatures vary, which defeats one of the purposes of a dust-tight or water-tight environment.  Most NEMA vents are provided to protect against dirt and dust using a normal filter to avoid that ingress while allowing some air flow.  However, as the applications of electronics moves into more hazardous environments, such as outdoors, protection against water and weather related elements reduce the value of those traditional products.  Bud Industries is pleased to announce a new series of IP67 rated vents that not only filter for particles while allowing airflow, but also it protects against water/rain/hose down and oils, even when the box is submerged for up to 30 minutes.

By use of an e-PTFE membrane, it is innately able to repel both water and oils yet allow sufficient air flow to balances the heat.  It operates both indoors and outdoors, is uv resistant, and so is the perfect solution at an incredible price. One concern that is overlooked in many applications is the impact of many heating and cooling cycles on the enclosure gaskets.  As the internal and external temperatures begin to vary, the box, particularly if it is plastic, slightly expands and contracts.  Over time, this continual flexing can cause the original gaskets to fail, leading to internal component damage.  The steady airflow provided by Bud vents avoids that temperature variation and keeps your components safe.  Read More >>

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 BRP Server Rack Series Is Plug and Play

19” Cabinet racks have been in use for almost 100 years since ATT first decided to set the standard for mounting of the termination and repeater equipment for toll cables in the early days of the telephone.  A few years later, the hole locations and distances between holes on the mounting rails of 1.75” was established and Bud Industries created its first “relay racks” shortly thereafter as we serviced the rapidly growing radio market.  Flash forward, and as is the case for many type of electronic enclosures, the rack specifications have remained consistent but the applications have changed with technology.  Today, instead of cable hubs and repeaters, these racks are likely to be used for server mounting, power supplies, as well as audio and data communications equipment.

Die Cast Boxes, the Ugly Enclosure with Great Appeal

Bud’s Die cast aluminum box may not be our best looking, but its great protection and low price are unbeatable

In the electronic enclosure world, we often say that our job is to make your projects look good.  We enclose all of your components, protect them from damage, and provide the shell that allows many products to be marketable.  We offer a variety of high style enclosures and boxes from small hand held clear usb drive enclosures to sleek server racks.  Alas, beauty is not the case with our traditional aluminum die cast enclosures (our CU die cast series) but they make up for it with solid protection and an incredible low price. 

Made from ADC-12 Aluminum alloy, they come with close fitting flanged covers that easily attach to the base with internal bosses maintaining the integrity of the box.  There are 15 sizes to choose from and many sizes have molded in pc mounting guides.  There are three styles of boxes available.  In addition to the original series, the CU-4xxx series has welded on external base plates to assist in wall or equipment mounting.  The CU-5xxx series comes with mounting flanges molded into the cover to provide not only easy mounting but increased security as the box needs to be unmounted to gain access to the internal equipment.  Read More >>

Bud Industries Explains NEMA vs IP enclosures

Bud's SNB series offers top protection at an amazing price all available from stock today
Bud’s SNB NEMA 4x IP65 steel enclosures

One of the questions we get asked most often is how do NEMA and IP ratings compare.  That is, can one find an enclosure with a NEMA rating and use it to fit a required IP rating?  The quick answer is no as there are different types of tests and even different testing bodies who set these ratings.  However, if your purpose is to just determine which NEMA is closest to a specific IP rating and vice versa, there are similarities.  First, some definitions.  Electrical enclosures are rated based on their ability to withstand a varying degree of environmental elements, including dust, water, and ice. In the United States, the National Electrical Manufacturers Association developed the NEMA rating for classifying an enclosure’s level of protection from those environmental elements. The International Electrotechnical Commission (IEC) http://www.iec.ch/index.htm has developed an alternative rating system, the IP standard, which stands for Ingress Protection. The standard format is “IP’ followed by two numbers which designate the level of protection. The first digit, which ranges from 1-6, specifies the level of protection from solids, and the second digit, which ranges from 1-8, specifies the level of protection from water. The higher the number is, the greater the level of protection. For instance, an enclosure with a rating of IP10 would offer less protection than an enclosure that is rated at IP54.

The following table summarizes the various IP number designations: Read More >>

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.

Why Select a Fiberglass Reinforced Polycarbonate NEMA Enclosure?

Terminal Box Electronic Enclosures in stock today
Bud is excited to introduce these IP66/67 rated terminal box electronic enclosures

One of the most consistent questions that Bud Industries receives deals with the best materials for a NEMA or IP rated enclosure.  Bud provides Nema and IP rated boxes in almost every material including steel, stainless steel, abs plastic, polycarbonate, fiberglass and die cast aluminum.  In the last few years, we have added an interesting combination of polycarbonate and fiberglass (10%) that is becoming increasingly popular for many good reasons.  This combination offers many advantages over both polycarbonate and traditional fiberglass materials when utilized for electronic enclosures.

Fiberglass is typically stronger than polycarbonate but because of the glass fibers it can crack upon impact.  Polycarbonate is much less likely to crack.  By adding a relatively small amount of glass fibers, the enclosure gains significant strength but still is basically crack resistant.   This makes this product especially useful in a factory or other environment where the box may be more likely to receive impacts from other materials or equipment.
