Shielding is the most effective protective measure against sources of electromagnetic interference. Interference is caused by electronic components, particularly those used in automated industries. Without professional shielding, such electromagnetic interference can lead to the failure of entire systems in the worst case. That is why EMC-compatible wiring is extremely important. To prevent failure or a negative impact on your system, we provide you with extensive knowledge and a comprehensive product portfolio around shielding.
Electromagnetic field interference
At the dawn of the electronic age, radio interference and interference with reception were a common occurrence during wireless transmission. Professional shielding was virtually unknown at the time. With the growing popularity of electronic devices in recent decades, an increase in the type of interference mentioned above was also observed. This circumstance led to the assumption that the interference was caused by the devices themselves. When adjacent live conductors (+/-) were examined, it was found that voltage differences existed between them. These differences cause every electronic device to emit electromagnetic interference. The overlapping of various instances of electromagnetic interference from different devices increases the overall level of electromagnetic interference. It has therefore become necessary to protect all devices against electromagnetic interference. The effects of electromagnetic interference can cause a great deal of damage, especially in industrial process and production technology. A particularly high level of immunity is therefore needed for electrical MCR (measurement and control technology) equipment. Device manufacturers must issue a declaration of conformity for their products to guarantee this immunity. Devices may only be brought to market if they comply with the EMC standard.
What is EMC?
European EMC legislation stipulates:
Electromagnetic compatibility is the capacity of a device to work satisfactorily in an electromagnetic environment. The device itself must not cause any electromagnetic interference that would be unacceptable for other devices present in this environment.
