  • The Basics of EMI Filters

    Wire Shielding Most electronic products give off electromagnetic interference and radiation through radio waves, electromagnetic waves, and other wavelengths. If not carefully protected and harnessed, these waves can interfere with the effective operation of other electronic systems in the area. Too much electromagnetic radiation exposure can lead to the scrambling of electronic signals and the warping of magnetic systems that will cause a machine to break down or malfunction. Manufacturers of electronics prevent the damage from EMI using a series of different methods. First of all, the manufacturers try to...

  • Do You Need Protection From Your Cell Phone?

    Wire Shielding Every person I know spends the greater part of their day on their cell phone. Whether that means spending countless hours having conversations with people or sending thousands of texts a day, I think it is pretty obvious that we are a nation that loves to talk. All that talking however, has been known to cause problems. Besides the obvious carpal tunnel implication from over texting on your cell phone, there is another danger that can come from your mobile phone that has many people worried. The electromagnetic...

  • Magnetic Shielding and EMI Regulations

    Wire Shielding Title 47, Part 15 of the Federal Code of Regulations is the code that regulates all devices that generate unlicensed transmissions. Many people may think of pirate radio or amateur ham radio broadcasts when they hear the words unlicensed transmission, but in reality any electromagnetic emission from an electronic device is an unlicensed transmission, and all electronic devices emit electromagnetic interference to at least some extent. Consumers are likely to realize at least one provision of FCC 47(15). Section 15.5 states that certain unlicensed emitters of electromagnetic waves...

  • Shielded Cable and Lessons in Electromagnetism

    Wire Shielding My parents exposed my brothers and me to music when we were very young. For some reason, my dad let me play around with his electric guitar and amplifier. When I got bored with that, I'd pull the cable out of the guitar and press my finger to the tip of the cable, which caused the amp to make a loud, intensely annoying buzzing sound. I later discovered that the buzzing sound was caused by the interaction between my body's own electrical field and the amp. I noticed...

  • The Importance of EMI Shielding Products

    Consumers have come to expect their electronic devices to work without interruption or incident, and quickly. Gone are the days of dad climbing up onto the roof to adjust the TV antenna, as are the days of unreliable dial-up Internet connections and asking the operator to connect our phone calls. Electronics continue to increase in their importance and popularity in consumer contexts as well as in all levels of industry and commerce. A basic fact of electrical engineering is that all objects that generate magnetic fields are capable of interfering...

  • Magnetic Shielding Efficiency for Wiring Applications

    Increasingly, many magnetic shielding applications today require a flexible, continuously enclosed shielding barrier to avoid pickup of external fields or radiation of interfering, unwanted fields.  One of the key components to a successful solution is choosing the correct shielding alloy.  Co-NETIC® AA has been used in many demanding applications and is one of the most recognized and specified brands of magnetic shielding alloy worldwide.  Co-NETIC® AA alloy is a proprietary material known for high permeability and used for reducing EMI in electrical / electronic wiring applications such as:  power feeds,...

Industry Information

Wire Shielding

Wire shielding is a specific type of EMI shielding that protects wires and cables from damaging electromagnetic energy. It is also employed when a product is suspected of causing electromagnetic energy, therefore blocking the waves it creates from affecting outside equipment. Electromagnetic interference is caused by the interaction of two separate magnetic fields produced by different electrical currents.

The shielding of wires and cables to limit electromagnetic interference is particularly important because they are abundant in industrial, office, commercial and home environments. As both a receiver and source of electromagnetic interference, insulating wires is necessary to keep EMI at a minimum. Like most electromagnetic shielding products, such as gaskets and filters, wire shielding is made from a variety of metal substances. Among those commonly used is aluminum, nickel, copper and steel. All of the mentioned metals have a high magnetic permeability. Alloys like Mu Metal, which is a trademarked combination of Nickel, Molybdenum, Silicon, Manganese, Carbon, and Iron are also often found surrounding wires. Shields for wires may come in a number of different forms. Braided wires can create a mesh coat that wraps around a wire, or a smooth surface jacket can be used to coat the wire instead. Sometimes numerous types of wire shielding are utilized at once to thoroughly deflect electromagnetic interference.

Wire may be bought with shielding already in place, or wire shielding kits may be purchased to cover and protect already installed bare wires. The type of shielding chosen depends on many factors, including the wire diameters and the amount necessary to cover all the wires in an environment. The shielding works by way of deflection, or by conducting the energy into the ground rather then into the wire it is protecting. Other forms of EMI shielding also work in this fashion, although the shape may be vastly different. For example, EMI coating is a spray on liquid that hardens on the surface it is applied to, then acting as a deflector of EMI as well as RFI energy. RFI, or radio frequency interference, is extremely similar to EMI, except that it moves in free space instead of through electrical wire. Wire shielding protects the mechanical wire source from RFI waves as well as the EMI. Products that require the safety of wire shielding include televisions, telephones, industrial machinery run by way of electricity, computers, light sources and many more products. These are utilized in virtually every industry, therefore making wire shielding a common necessity.
