The most common perpetrators of EMI include computers, wireless devices, power lines, microwave equipment, and high-frequency electronics.<\/p><p>EMI can cause electrical noise, such as hum or static electricity, but more worrisome is its ability to interrupt power, degrade signals, or prevent the transmission of data. Shielded cable connectors can deflect EMI, preventing your electrical equipment from radiating EMI. Here are three things you need to know before you choose an interconnect solution.<\/p><figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" class=\"wp-image-5465 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-9.jpg\" alt=\"\" \/><noscript><img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"450\" class=\"wp-image-5465 lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-9.jpg\" alt=\"\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-9.jpg 600w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-9-300x225.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/noscript><\/figure><p>1. Shielded cables require shielded connectors to ensure proper grounding and shielding.<\/p><p>Shielding the cable without shielding the connector is only doing half the job. Unless the connector has a similar level of shielding, your cable assembly will not achieve maximum EMI coverage. In other words, unless both components are adequately protected, you will not gain the benefits of shielding.<\/p><p>2. There are two main types of cable shielding to choose from.<\/p><p>While you will find variations of shielding, such as combination or spiral shielding, the two most common types are foil and braid. Both have specific advantages and disadvantages that require careful consideration.<\/p><p>Foil shielding involves a thin layer of copper or aluminum that wraps around a cable or connector. This type of shielding is lightweight, provides 100% high frequency coverage, and is relatively inexpensive to produce. However, foil shielding is also very fragile, which limits its flex life and mechanical strength.<\/p><p>Braided shielding involves a tight criss-cross pattern of thin tin or copper wires wrapped around a cable or connector. This type of shielding is strong, flexible, and effective at all frequency levels (especially low frequencies). However, braided shielding does not guarantee complete coverage and is bulky, which makes it more expensive to produce and unsuitable for tight spaces.<\/p><p>3. The effectiveness of shielded cable depends on three factors:<\/p><p>Type and thickness of shielding material.<\/p><p>Are there any openings in the shield (such as small gaps in the braid).<\/p><p>The effectiveness of the adhesive connection to the ground.<\/p><p>Overlapping the braided shield with the foil shield can extend coverage and protect against outside interference, while properly grounding or &quot;earthing&quot; the cable will reduce the cable&#039;s radiated signals to increase the shield&#039;s effectiveness against EMI.<\/p>","protected":false},"excerpt":{"rendered":"<p>Electromagnetic interference (EMI) occurs when electrical currents, magnetic fields, and radio frequencies disrupt the flow of energy in nearby circuits.
