  • The Importance of Shielded Cables

    Electromagnetic Shielding Many factories are known for their electromagnetically-charged atmospheres. In these factories, it is extremely important to protect the operation of equipment from the EMI charges output by other machines and processes. If the machines cannot operate properly, then the entire factory can become un-operational. The best way to protect these machines from unwanted EMI exposure is to shield all machine cables with EMI shielding to protect the cords and electrical processes from EMI. EMI shielding companies provide a variety of cable protection methods that are highly effective at...

  • Provide Additional Electromagnetic Shielding with Custom Fabric

    Many companies have to protect their machines and other products from dangerous radio frequency electromagnetic radiation and electromagnetic wavelengths that can damage delicate machinery and equipment. Often, computer parts and other delicate machinery will malfunction in the presence of electromagnetic radiation. When this occurs, the machine cannot perform according to the desired specifications, and may cause problems with the manufacturing process or even break the machine altogether. While many machines already come with built-in electromagnetic shielding, not every machine does. Other machines may have a certain type of shielding, but...

  • Elasto Proxy Supplies EMI Shielding for Military Electronics and Medical Equipment

    Elasto Proxy, a supplier of specialty sealing solutions and custom fabricator of rubber and plastic parts, is supplying EMI shielding for military electronics and medical equipment. Electromagnetic interference (EMI) can disrupt sensitive electronic components and endanger the lives of the warfighters and hospital patients who depend on them. The causes of EMI are numerous, and include everything from radio transmitters and electric motors to fluorescent lights, power lines, and computer circuits. Regulations limit unwanted electronic emissions, but EMI shielding remains mission-critical. Whether aboard a navy frigate or inside a hospital...

  • EMI Shielding and Security

    Electromagnetic Shielding Few industrial professionals are not aware of the importance of electromagnetic shielding in the protection of sensitive electronic devices. Electromagnetic interference can disrupt the operation of a wide variety of unshielded electronic devices. Because there are so many contexts in which electronic devices are relied upon within industry, EMI shielding is an important tool for protecting the functionality of most of those devices to at least some extent. What those same professionals may not have known, though, is that EMI shielding can be used to protect them in...

  • MuMetal: First Among Magnetic Shielding Materials

    Electromagnetic Shielding MuMetal's the name. Low-frequency magnetic field attenuation's the game. Whether it is needed for magnetoencephalography or for photomultiplication, MuMetal is an excellent magnetic shielding choice. Here at the EMI Shielding blog, we do our best to make the realm of such complicated concepts as electromagnetism and magnetic shielding accessible to everyone. Understanding MuMetal can enrich a person's understanding of magnetic shielding products generally. All said and done, MuMetal is just a fancy word for a nickel-iron alloy with a pinch of molybdenum and copper (though different companies offer...

  • Electromagnetic Shielding: Averting Crises Daily

    Electromagnetic Shielding Many people tend to stare down their food as it cooks in the microwave. At first glance it might seem like staring at a microwave from a short distance is not terribly smart behavior. After all, the process involves using microwave radiation to heat objects. Rest assured, though; microwave ovens pose no risk to riveted onlookers. They are encased in electromagnetic shielding. Take a look at your microwave if it's nearby (or look one up if it's not). Notice how you can see through a metal mesh into...

Industry Information

Protecting Industries from Electromagnetic Radiation

With so many devices in the modern world emanating electromagnetic radiation, many people are concerned with the safety of these devices. Since electromagnetic products have only been in use for a few decades, it is impossible to determine if they are truly safe.

Luckily, electromagnetic shielding can block EMI and RFI radiation. Shielding comes in many forms, as thick as an actual sheet of metal and as thin as a simple coating of paint. EMI shielding manufacturers have a variety of ways to keep radiation from damaging people and sensitive equipment. EMI shielding is used in factories to protect sensitive equipment from damage and it is used in cell phones and other personal electronic devices to prevent the waves from passing through the body.

Other industries, such as the military and other safety organizations also use EMI shielding to protect equipment and people. Certain shields and coatings are used for tasks like, preventing waves that can trigger harmful devices and disrupting pulses that can damage sensitive electronics. Some coatings are simply necessary to prevent two forms of waves from interfering with one another, such as the waves produced by two different machines in a factory.

Without the protection that EMI coatings and shields provide, many industrial companies would have a lot more problems. Machines that interfere with one another could cause expensive damages. Radiation passing into workers could potentially cause health problems. It is essential to protect the equipment and people in a factory or any commercial setting from the potential of EMF or RFI radiation.

Electromagnetic Shielding

Electromagnetic shielding is a barrier which protects electronic equipment from ambient electromagnetic interference. Electromagnetic interference, or EMI, is the magnetic field which is created by electrical currents; EMI can travel along wires, electrical circuits and conductors, while radio frequency interference (RFI) is radiated electromagnetic noise, which travels through the air as radio waves. Both EMI and RFI cause similar effects, although EMI typically operates on lower frequencies than RFI.

EMI enclosures, EMI coating, EMI gaskets and  EMI filters are used as magnetic shielding to guard sensitive electronic equipment. EMI and RFI are created, by widely varying degrees, by everything which conducts electrical energy, including electrical wires, electrical appliances, computers and all electronic equipment. Signal-bearing electronic devices such as mobile phones give off RFI. Normal electrical currents are disrupted when moderate to high levels of EMI or RFI are introduced; un-channeled electromagnetic signals and radio frequency waves can act as "noise", magnetically altering normal flow of electrical currents and impeding the flow of electrical energy. Electromagnetic shielding and EMI filters can be found in medical devices, computers, mobile phones, stereo systems, television sets, windows, vents, fabrics, foils and even walls.

Shielding sensitive electronic equipment from electromagnetic interference and shielding high EMI-emitting equipment from contaminating other equipment can be achieved by enclosing equipment in a conductive EMI absorbing material or by coating equipment or equipment enclosures with EMI coating. Thus, electromagnetic shielding can be accomplished through evident physical objects, or through unapparent objects. Electromagnetic shields are also called magnetic shields, EMF shields or RFI/RF shields and may be made from conductive rubber, like nitrile or silicone, or metals with high magnetic permeability. Metals such as nickel, copper, steel and aluminum are commonly used, although the industry standard magnetic shielding material is Mu-Metal®, an alloy of nickel, iron, copper and molybdenum. Many industries depend on EMI shielding products to protect communication systems, in industries such as medical, telecommunication, stage production, sound production and many others. Within circuit boards and CPUs, most problematic EMI comes from electromagnetic cross-talk between different components on the same board as EMI travels across wires and conductive materials.
