The electrical engineering sector covers the field of connectors, sensors and casing seals. These applications arise in the industrial and automotive sectors. Fulfilling the requirements of certain IP protection classes and in terms of electrical conductivity are only two of the aspects which have to be taken into account in this segment. Mouldings and O-rings are the product groups most frequently applied here. As a material, silicone is one of the most widely used, while sensors call for the use of the entire range of materials, as many different media including temperature and fluid levels have to be measured.
