Electronics engineers are very familiar with the need for electromagnetic interference or EMI protection and will consider in their design good board layout, filtering, grounding, signal integrity etc. to try resolving EMI at its source. However, shielding of the enclosure is just as important and solves the problem of radiated emissions and susceptibility. Shielding is a mechanical fix for an electrical problem and the enclosure design engineer should be aware of the types of gaskets available and their different attributes and ensure there is enough land area on the enclosure seams, doors etc. to fit the gasket. TE offers comprehensive EMI products and EMI/EMC solutions providing consistent protection.
Conductive elastomers are fully cured silicones or fluorosilicone loaded with a variety of highly conductive particles providing superior EMI/RFI shielding performance combined with excellent environmental sealing. The various conductive fillers are designed to ensure galvanic compatibility whilst providing low contact resistance between mating surfaces. Kemtron Ltd.’s many years of manufacturing experience combined with quality control and compliance testing ensures our conductive elastomers are suitable for the most demanding situations, offering consistency time after time.
