RF-shielded enclosures are used to protect electronic devices and equipment from external electromagnetic interference (EMI) and to prevent the emission of electromagnetic radiation (EMR) from the device or equipment.

Electromagnetic radiation is present all around us, and various devices emit different frequencies of electromagnetic radiation. These frequencies can interfere with the functioning of electronic devices, resulting in data loss or system failure. This interference can come from sources such as power lines, radio and TV broadcasts, and other electronic devices.

RF-shielded enclosures, also known as Faraday cages, are made up of a conductive material that blocks out electromagnetic radiation. These enclosures provide an electromagnetic barrier between the electronic device and the external environment, effectively isolating the device from unwanted electromagnetic interference.

In addition to protecting electronic devices from external electromagnetic interference, RF-shielded enclosures are also used to prevent electromagnetic radiation from the device from leaking out into the surrounding environment. This is important in applications where electromagnetic radiation could cause interference with other electronic devices, such as in medical or military settings.
