Who or what is NEMA? NEMA is the National Electrical Manufacturers Association (USA) and they provide a designation for enclosures, including computer enclosures as guidance to the level of protection they offer. NEMA is the United States equivalent of the International organisation IEC (International Electrotechnical Committee). The IEC issue IP ratings (Ingress Protection) that are […]

Dust can be one of the biggest enemies of a computer. It can get into the workings of a machine and clog up filters and vents. This can cause over-insulation and can short circuit electronics. Dust is one of the primary reasons for the early failure of a computer, so it’s important to protect PCs […]

Water and electrical equipment such as computers are not happy bedfellows which makes using a computer in wet areas a hazardous undertaking. However, water is liberally used in industrial areas particularly food preparation areas. Unfortunately, most computer enclosures are not designed with any waterproofing in mind and taken into an industrial environment these off-the-shelf computers […]

Having worked in both an office environment and an industrial shopfloor I am only too aware of the differences in working in the two extremes. Whilst on a shopfloor you can no longer walk around in your best suit and day shoes. Instead workers who are employed in industrial areas have to wear protective clothing […]

When selecting an enclosure whether it is for an industrial computer or other type of electrical advice it is important to understand what protection it offers here is a list of the American NEMA codes that signify the protection the enclosures offer. Here are some of the most common NEMA codes used in the industrial […]

With industrial computers it is important to understand in what conditions the machines can be used in and what elements they offer protection against. NEMA codes are similar in effect to the European IP rating system (Ingress Protection) but are established by the National Electrical Manufacturers Association (NEMA) of North America. However, unlike the European […]

Many businesses spend a huge amount of their annual budget on advertising and you don’t need me to tell you that advertising can be really expensive but it is worthwhile if it generates income. However, in the current economic climate and with customers reluctant to make investments adverts yield less income than they were a […]

Here are some of the most commonly used IP codes in the industrial computer enclosure industry. The IP codes signify how much protection the enclosures offer against the penetration of foreign bodies and permeation of water. The two digits signify the protection against solid objects (the first digit) and liquids (the second digit. The greater […]

It is commonplace in the industrial computer industry to keep coming across the term ‘IP rating,’ this article will examine the IP rating system, explaining what it means and where it is used. IP stands for ‘ingress protection’ and is usually assigned to enclosures and in industrial computers this is the enclosure that houses the […]

A recent study has discovered that computer keyboards house more germs than toilet seats even harbouring potentially lethal bacteria such MRSA. Experts say there are over 3,000 microbes per square inch on the average keyboards compared to just 49 microbes on a toilet seat! With the increasing use of computers in the health professions they […]
