Electromagnetic compatibility (EMC) as a prerequisite for efficiency and safety



The electrification of our everyday life is progressing rapidly - at an unstoppable pace so it seems. This is a development that can also have unwelcome effects on sensitive electronic systems as the applicable standards for effective shielding from electromagnetic radiation lag behind technical advancements. All the more reason, therefore, to identify and correctly assess potential risks in good time.


Risks when operating electronic equipment

A host of electronic systems used for diagnostic purposes, monitoring, treatment etc. are focused in areas such as hospitals or laboratories, military facilities or in industry. Internal or external influences conditioned by electromagnetic fields can result in significant disturbances and have fatal consequences.


Risks during data processing

An unexpected problem in electronic data processing or time-consuming disruption of the computer network are phenomena which, regrettably, are not uncommon. To an increasing extent they are due to electromagnetic interference.

Risks for data security

Data security has to be a prime consideration wherever sensitive data are processed. Entire IT systems can be disrupted from outside with relatively little effort. Suitable measures should also be taken to prevent unauthorised access to sensitive data. Using appropriate means, data on computer screens, graphics and video cards can be accessed even without cable connection from as far away as about 100 metres.


The electromagnetic compatibility (EMC) of an electronic system is assured if:

  • the electromagnetic radiation generated does not interfere with its own system
  • the electromagnetic radiation generated does not interfere with other electronic systems
  • the system is immune to interference from other electronic systems
