Why Is EMI/RFI Shielding Important For Cable Assemblies?

Why-Is-EMI-RFI-Shielding-Important-For-Cable-Assemblies

The world is full of smart and intelligent equipment like cellphones, WiFi, Bluetooth, etc. whose signals are crowding the airwaves. This crowding results in signals from one device crossing over another; thus resulting in thousands of signals intersecting together, and creating a lot of electrical noise. These signals are targeted by cable assemblies, who work as antennas to draw in or emit signals, thus attracting the electrical noise, which results in the phenomenon that we call electromagnetic interference (EMI) or radio frequency interference (RFI).

With the effect of EMI/RFI, cable assemblies experience poor signal quality, loss of data, or even complete disruption of the functioning of electronic equipment and also other nearby components. You may have noticed how when your cellphone is kept near your television, an incoming call may result in the television to waver its picture quality; or when kept near an audio equipment, may produce a buzzing sound. While all these instances are normal, can you imagine how severe or dangerous the effects can be if instead of the television and audio equipment, there is an electronic medical device, a nuclear operation, or a high-voltage contact switch nearby!? EMI/RFI in such situations can prove to be extremely disastrous!

This is the reason why some regulations are set to enforce EMI testing to ensure that the product doesn’t generate EMI/RFI disturbances that can impact other electrical circuits; and that the product performs even in electromagnetic environments, without being affected by interferences. The only solution to prevent such disasters from occurring is EMI/RFI shielding. An EMI/RFI shield encases the cable assembly conductor such that it protects the assembly against electrical noise. Such shielding may work to deflect electromagnetic energy, or pick up the energy and ground it. As easy as it may sound, the process is actually difficult. This is because EMI/RFI radiates from an electronic source in a wave-like pattern. With the increasing number of sources that create signals, smaller and faster devices create smaller and faster waves, which makes it very difficult to block them. However, when specialized and proficient cable assembly manufacturers in India work to produce EMI/RFI shielded cable assemblies, things become simpler and safer.

Looking at the above issues associated with EMI and RFI disturbances, and how difficult it is to block these waves, it is always advisable to not invest in off-the-shelf cable assemblies. Instead, you must partner with expert manufacturers and engineers who provide the most reliable solutions, and showcase specialized expertise in EMI/RFI shielded cable assemblies. One name you can approach is Miracle Electronics, the leading cable assembly manufacturers in Germany, where you can get perfectly customized solutions for your individual application. And, concerning the quality of products, there is nothing to worry about as the company’s production processes are certified for quality, and the quality of cable assemblies produced are legally approved for platform specific applications. Furthermore, every cable assembly produced is tested for dimension, weight, continuity, environment compliance, and every other element that needs to be checked and verified, before being delivered to the clients.
