In the event of inadequate shielding, electromagnetic waves and electrostatic fields cause unwanted voltages and currents resulting in mutual interferences of neighboring equipment. The consequences are audible humming, functional impairments and signal interferences (e.g. of sensors and electronic control units), plus a higher risk of fire due to overloads up to and including total equipment failure. Protection films for EMI shielding from Schreiner ProTech provide relief: They reduce the hazards emanating from electromagnetic radiation.
