EMI Definition

EMI which is standing for Electromagnetic Interference is referring to a disturbance that is produced by an external origin which is interfering with an electrical source or a circuit. Similar to a radio frequency interference the EMI when caused can significantly impact how electronic devices operate leading to them malfunctioning or ceasing to work completely.

The reason behind why electromagnetic interferences happen can be due to a close encounter between electricity and magnetic fields. When electronic devices come into contact with EMI the datacenter cables can experience a surge in voltage and can lead to the erasure of data on hard-disk drives and solid-state drives.

How to prevent EMI?

Since the discovery of the electromagnetic interference there have been developed numerous options for stopping such an event from occurring altogether to prevent the before mentioned outcomes. We shall go over the three most popular methodics of putting a stop to EMI.

The first solution is always recommended to pay attention to wire shielding especially with an added bonus of twisted wires to put protection to the maximum from electromagnetic interference. On the usual occurrence this type of wiring is installed by a professional team as it is quote treacherous to handle it without training.

The next on the list is making sure you put adequate grounding practices to use by connecting sensors to stable grounding. On top of that it is recommended that you skip the overlaps of grounding and give preference to a single source since the improper installation could lead to you failing to overcome power surges.

Last but not least is making sure you are remembering the proper routing of the cable, for instances, be prepared to route signal cables away from electrical circuits and outlets as they can cause an EMI themselves.
