Housing technology for nitrogen oxide sensors

NOx is used as a collective term for nitrogen monoxide and nitrogen dioxide. These gases are produced, for example, during the combustion of fuel in the engine and are then guided through the aftertreatment in the exhaust system. This process reduces the emission of dangerous nitrogen oxides to a minimum and serves to improve air quality.

High-quality NOx housing technology

The complex electronics of nitrogen oxide sensors require a robust housing. Mounted near the exhaust system, the thermal and mechanical load exercised by temperature differences and vibrations strains the plastic housing. Glass-fibre-reinforced PBT withstands these stresses over very long periods and can also be processed dimensionally accurately. In addition to dimensional accuracy, cleanliness plays a major role in housings for miniaturised electronics, especially in bonding applications. Besides avoiding metallic particles in the process, the bonding surfaces must also be protected against any greasy contamination. This must be taken into account when designing the equipment, gripper systems and tools. In addition, the inserts and finished parts have to be handled in a specially coordinated procedure. Production on fully automated lines allows large quantities to be manufactured while achieving excellent quality. This also secures a competitive advantage in globalized markets. Regular reviews in line with our IATF 16949 certification guarantee that the quality of our products reliably meets the highest standards.

Housing technology for sensor electronics from the specialists

Our manufacturing method allows us the greatest possible flexibility in accommodating our customer’s requests. This applies, for example, to the housing shape and size as well as the selection of the materials used, such as plastics, contacts or bushings. A housing specially designed for the part and customized constructional features result in a truly customized product.
