How to Determine and Pinpoint the Exact Dimensions for Plastic Electronics Enclosures?

We recently just moved and re-arranged the furniture in our living room. My dog’s own crate has always been placed in the corner of our living room. Along wit some of our new furniture, there was no longer a room available for my dog’s crate. So we have to identify or look for another space for the crate. Since my dog is a medium sized Labrador, the crate is super huge.

To be able to move this into a new space or location, we have to run our creativity. We have to find a space spacious enough to fit the crate so that it can crate up and be installed on the wall. This in return, reminded me of the video game, Tetries.

I was being reminded of this fact while I was talking with a customer just the other day. The customers often call to our company because they want to ask for help in selecting the right enclosure. This person was particularly looking for a “a CD ROM sized enclosure”. When I told the customer that I would be more than happy to find something similar to that size range, the customer told me that it is just what he exactly needs as per dimension wise.

The customer then was really hoping to produce a product that would be able to slide into the same area like the optional CD ROM available in the computer. In order to fit that exact space, the customer need the right dimensions. This is too large and it would not eventually fit, and too small that it will not hold very stable.

As we have recently discovered, this problem presents several difficulties on a very few levels. While the majority of the manufacturing companies will shape the enclosures with several type of ranges to be able to offer the best choice available to the customers. However, it is nearly impossible to be able to find the exact match for the dimensions within a different product line.

There are companies that offers wide range of sizes and different styles of electronic enclosures. Several of their enclosures are mostly rectangular in shape, but majority of them have the same ratio of length that ranges form width to height. We just recently found out that the most used size range is 2 x 3 inches, and in line with this there are several options that exists within the 1/2” range. While each of them consist of a very deffierent depth.

This is to be able to give you the best and with the most options possible to help in finding out the most perfect enclosure for the companies’ needs.

What are the Other Available Product Lines for NEMA-Rated Electronic Enclosures Manufactured from Plastics?

Being a Cleveland sports fan is very very hard. Because of the team’s last year performance, their most notable low game point happened in July. It was also nationally reported that LeBron James have finally decided to leave the Cleveland Cavaliers. These infamous words by James “I have chosen to take my talents to South Beach” I think will haunt Cleveland fan’s memories forever.

Just this morning before the broadcast of James’ decision, the Cleveland’s owner – Dan Gilbert – promised to make sure that his team will bring the championship to Cleveland. Even before Lebron can win one for Miami. After the game of not so famous ‘10-‘11 season, I was really excited to see the draft of 2011 NBA as Cleveland has already accepted its 1st overall pick. Of course, with the excellent opportunity for them to increase their talent on the bench.

Just like the Cleveland team, who just recently got a new talent in the draft, there are enclosure manufacturing companies who are getting ready to launch their new product lines. These companies will be on the run for the expansion of their top line NEMA-rated electronic enclosures. And this line also has the additional sizes and version available for their respective series.

With these new developments, there will be no longer a need for the acquisition of a different flange kit available to the NEMA boxes. As these newly updated enclosures will constitute a surface-mounting flanges that are molded directly on the box. This is a new and convenient features of the flanged NEMA boxes that comes with their accessibility.

The customers will also be able to remove the cover of the enclosure without removing the electronics enclosure from its surface it is currently mounted on. In addition to this, the brass inserts also allow for the re-entry into the enclosure box. Given that you can do this for unlimited number of times. And also, always remember that the enclosure series NEMA rated enclosures are generally design to fit to IP65 of IEC 529 and adopt the NEMA 1, 2, 4, 4x, 12 and 13 specifications.

All About Server Rack Air Conditioning

With the warm weather quickly approaching this year, it is very vital for companies to make sure that their portable spot cooler is working perfectly fine. Just in case that companies do not have a good portable spot cooler for the server racks, this is the perfect time to get one. There are companies that sell a wide variety of portable spot coolers as well as accessories that will make your equipment cooler when you need them to.

The portable spot coolers are the best way just in case the normal air conditioning system in your server racks are not working well. Or if they are working, they are not releasing enough cool air to lower the temperature of your server racks. There are companies that sells units from 10,000 Btu/hr to 92,000 Btu/hr. In addition to this, the 10,000 BTU unit can be installed unto the server cabinet to achieve the maximum efficiency with the purchase of additional kit. Whatever the companies’ cooling needs are, there are widely available spot cooler solutions.

In addition to this amazing spot coolers, companies are also selling wide variety of server racks accessories that are widely available for directing the air flow, reducing the exhaust heat out of the room, pumping condensate and so much more. What is more exciting about this is that the units are maintained to be kept in stock and they are already ready to ship. So that the customers can get their coolers ASAP.

Companies also offer a 1 year warranty for the parts and accessories of this product. The total labor for the whole unit and included is the 3 year warranty on some parts and labor for the compressor. Rest assured that companies that will purchase a portable spot cooler will surely get a good investment.

NEMA Electronics Boxes are Stable: Don’t Worry

I believe for my entire life I have been a little bit grace-challenged. Ironically, most of the time I do better when I wear heels compared to flats, rubber shoes, or tennis shoes. Which is for me, this comes at a good advantage because I am only 5’1” and I need the additional inch lift from heels. I feel like I am like Sandra Bullock where she portrayed the character of tom-boy cop who goes undercover as a beauty queen.

As she walks into the movie, she just woosh her way in wearing her elegant, sassy dress paired with stilettos heels – and she accidentally just falls flat on her face. You read that right. And when I think about it, I came up with the realization that it is all about being stabilized. Protecting myself from the crushing pain from a fall. It is either I need an equipment or a tool to help me stand tall and upright (even if that means planting my feet in a dancer’s position) or I have to keep my momentum moving so that I will not fall.

The plastic enclosures also come with good stabilization process. The material which it was made has an added UV stabilizer to be able to protect the enclosure from the degrading effects of UV light. This is somewhat similar to applying the right amount of sunscreen for you to be able to protect your skin from the harsh sunlight. With this in mind the plastic manufacturers also add UV stabilizers for their plastic material – called benzophenones – in the raw plastic material before it was injected in molding the product.

The additional additives in the plastic material works by absorbing the radiation coming from the light and it slowly disperses the absorbed energy as low-level heat. This helps the plastic material to keep from the free-radicals to be formed in the material.

Therefore, when it comes to stabilizing the electronics enclosure, the UV stabilization is crucial because it helps your NEMA enclosure from having material degradation while it is being used in engineering projects. Especially if it is installed in harsh environments. There are enclosure companies that offers plastic materials that comes with UV protection, and these enclosures are stabilized for outdoor use.

The company only needs to contact the enclosure manufacturing company to inquire of their plastic enclosures if it comes with UV protection. It is always recommended to make sure that this is the case. It is hard just to speculate things when the products are seen on the internet. With today’s weather status, it is recommended for plastic enclosure to have UV protection to avoid early material degradation. It will cost a lot more for the company if they have to quickly replace the enclosures they bought because the plastic material is starting to degrade.

The Reason Why NEMA Electronic Cases Don’t Degrade

During summer in Cleveland, it is a smack dab in the middle of the unimaginable humidity including the sweltering high temperatures and balm nights. If you decided to go and step outside, you will start dripping in unimaginable sweat.  Because of the increase in humid and one can not really tell if they are just sweating or it is just because there is too much liquid collected from the air. One can say that they really hate bitter cold winters, but I will still choose it over any day rather than suffer in heat and humidity.

This is why when it come to electronics enclosure, the NEMA 4 and NEMA 4X rated ones seems to be so cool when it comes to this kind of weather. They are made to endure and withstand the heat because they are designed and engineered using a flame-retardant polycarbonate material. Together with a UL94-HB flame-rating, this enclosure becomes UV stabilized. The impact this material can resist and withstand in terms of temperature ranges from -40 Celsiums to +120 Celsius.

Even of the enclosure cases are not situated or installed in an area that gets water, the present moisture in air can still damage the electronics. The gasket which is provided with the NEMA rated electronics enclosure can help in protecting the internal electronics from that type of moisture. In addition to this, the housings also come with standard and stainless steel enclosure screws.

For the WP NEMA enclosures, WC NEMA and WA series NEMA enclosures – they are all made, designed, and engineered in line with IP65 of IEC 529 and NEMA 1, 2, 4, 4x, 12 and 13 specifications. The electronics enclosure is also listed to have the specifications of UL.508-4x

Some enclosure manufacturing companies can also give NEMA specific mounting boss screws. The 6mm screws can be utilized to effectively secure the PCB unto any of the internal mounting bosses that are carefully molded into the enclosure.

Different Types of Enclosure Seals and Gaskets

Gaskets are necessary enclosure accessory to help seal the electrical enclosures according to the set of standards published by National Electrical Manufacturer’s Association (NEMA). The gaskets can be used from ratings 1 to 12. Some of the most popular ratings for indoor enclosures are 12 and 13. The common enclosures for outdoor application are 3, 4, 4x, 6, and 6P.

The electrical enclosure standards are very crucial because they have direct effect on safety and protection. It can also help the customer choose and obtain the right product for their company or business needs.

With this in mind, the good gasket design in an enclosure is very crucial for the engineer to make a very good seal and it is as important as the gasketing material itself. The design will bring a good impact on the functionality, aesthetics, and the overall performance.

Some of the common gasket types are:

Stripping – these gaskets are being supplied in rolls with a material slit to be able to determine the width that can be cut or separated in length by using the assembler. The low scrap-rate makes the stripping of the gasket cost-efficient. Despite of this, the corner seams of the material roll may make the system more susceptible to wear and leakage. This will only happen if the gasket is not properly designed or even assembled.

Die-cut – Once the material is cut using a steel-rule die, water-jet, or laser, the die cutting process helps in eliminating the corner seams of the material roll. Die-cut gaskets are very popular and common once the complexity of the design does not allow for the stripping or if the overall size of the gasket will not bring in larger center scrap. This can be lessened by designing a “fold-out” gasket.

Form-In Place – when it comes to dispensing the component, an elastomer is applied in liquid form and it is directly applied on the enclosure. The elastomer liquid then forms into a foam and it cures at room temperature. The form in place is usually is cheap to apply and it yields the most benefits once the gasket design becomes very complexed. Or else it will result to an important yield loss without the die-cut shape.Bulb Extrusions – this process can be tailor-fitted or designed specifically for abrasion and/or possible environmental resistance by utilizing very durable and high quality elastomers. The hollow center gives provision and allowance for compressibility as the material can be naturally firm or steady. The skinned surface of the gasket on all sides combined with high density minimizes and decreases any possible water ingress on the enclosure.

Designing Enclosures that can Give Protection Against Water and Object Ingress

In this article, I want to share with you the knowledge that I have in designing and creating enclosures that should be able to withstand some of the extreme, harsh, and worse environmental hazards. This discussion would eventually bring us to the issue between NEMA and IP rating standards. Because these two standards most of the time brings confusion to how they work. With this in mind, this article is meant to somehow clear the air of confusion surrounding this subject. In order to make this more simpler, I will only use NEMA ratings for the majority of specifications but there are IP counterparts for the NEMA ratings I will mention. To make this article relatable.

As the writer of this article, I would like to make it to a point that I emphasized on the importance of the designers’ consideration on what they are trying to get in designing enclosure. Design engineers should make sure that their agendas in designing the enclosure should be clear. Are they trying to achieve environmental protection the enclosure can give? Or are they trying to comply to the formal standards and requirement of NEMA for electrical enclosures? The latter might have been greatly influenced by the owner of the company or the manager of operations.

With this in mind, the enclosures should be made sure that these will really deliver what they are designed for. There are several variables a design engineer should consider in choosing the right type of enclosure they should have for their company. There are basic enclousres that gives basic protection from any type of solid object ingress. A higher NEMA rating might mean that this enclosure will give higher protection. Unlike the IP ratings, NEMA rating will give the protection it can give aside from the water or solid object ingress.

The main difference between IP and NEMA, the latter gives the level of protection it gives for corrosion protection. For the enclosures that will be installed in very harsh environments, it is important that one of the basic needs for enclosure property is its capability to withstand corrosion. There will be also times that the enclosure will be parlty or totally submerged in water so any NEMA rating of 6 will be helpful.

With this in mind, NEMA enclosures types is primarily set to promote certain standardized product specifications for electrical devices. NEMA is designed to have specifications on how the enclosure should perform given the certain type of environment it will be exposed to. For harsh environment, it is recommended that type 6 will be used. Aside from these features, NEMA ratings are designed to:

1. Protecting personnel from hazardous internal parts Give protection for personnel that might be exposed to hazardous internal parts and;

2. to protect the enclosure against damage from harsh environmental hazards.

How System Integrator Delivers Value in Today’s Technology

The one great function of system integrators is they are in the industry to help companies solve automation problems. This happens by integrators giving the time, talent, and technology that is crucial to convert a plan into a completed company project. Once a manufacturing plant is prepared to make its operations bigger, the production systems should also upgrade its processes. However, the main question that should be answered is where in the part of the expansion a system integrator can help? 

To help companies answer this question, the Control System Integrators Association (CSIA) a body formed for independent, professional service providers that utilize hardware, software, and communications products are ready to give the clients within a specific industry the best options for systems integration. This includes control and information systems. With this in mind, this body dictates that the system integrators create design and implements complicated systems for the end users of the process in different industries. Such as manufacturing, process plants, and other industrial facilities. 

The Siemens Digital Factory is popular with their engineering capabilities and information technologies that helps businesses automate their manufacturing processes. This covers all types of businesses from the plant floor to the corporation and enterprise level. The automation processes enable the company owners and manufacturers have cost-efficient ways and practical energy use. In return, this helps in the increase in production while decreasing the harmful effects on the environment. 

There are articles that discusses about different system integrators. There is one case study that involves water and wastewater treatment plants. In this study, there is PLC involved. The project involves the replacement of the PLCs or programmable logic controllers. There is also converting protocols, upgrading supervisory control and data acquisition (SCADA) system both hardware and software. The second case involves PLC consolidation and the upgrade of SCADA software. With this in mind, both projects are really successful. 

The another case study shows how the users of the systems such as: insurance companies, system manufacturers, different government offices. These companies and offices can identify their need for a process safety system. This system should be designed, operated, and well maintained over its life cycle. In the article, they list the set of key codes and different standards that are very well applicable to the different process of other industries and they give different perspectives about the fulfillment of legacy systems.
