To do this, an aluminium fastener is applied directly to the weld point. Aluminium is non-ferromagnetic and complements protection against external influences. The complete pipe is then given a plastic coating made of PP or PA several millimeters thick. The aluminum component is thus completely concealed below the surface.    <\/p><p>Nevertheless, it must be checked during the ongoing process whether this fastener is present and in the correct position. At the same time, the steel pipe itself must not be considered a &#8220;signal&#8221;.

Although many sensor systems react fundamentally to metal, they do not distinguish between ferromagnetic and non-ferromagnetic materials.

Thin aluminum foils are often processed or transported there \u2013 for example, as a barrier or protective layer. These films are very thin, highly reflective and often difficult for optical systems to detect. At the same time, there are other metal parts in the area, such as steel, which should not be considered a signal.   <\/p><p>Inductive sensors with selective behavior solve this task particularly elegantly. They react specifically to non-ferromagnetic metals such as aluminum and ignore ferromagnetic components. This means that even a thin aluminum foil can be reliably detected in the process without the need for complex image processing or additional evaluation. The underlying technology corresponds exactly to the principle that is also used for coated steel pipes \u2013 only in a different form of application.   <\/p><p> <\/p><figure id=\"attachment_21421\" aria-describedby=\"caption-attachment-21421\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-21421\" src=\"https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6-1024x576.jpg\" alt=\"Inductive sensors monitor aluminum foil on packaging containers on a conveyor belt in a production line\" width=\"800\" height=\"450\" srcset=\"https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6-1024x576.jpg 1024w, https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6-300x169.jpg 300w, https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6-768x432.jpg 768w, https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6-1536x864.jpg 1536w, https:\/\/we.automation-inside.com\/wp-content\/uploads\/2026\/02\/121-InduktiverSensorK1_Aluminiumfolie_6.jpg 1920w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-21421\" class=\"wp-caption-text\">Aluminum foil detection by inductive sensors in the packaging line<\/figcaption><\/figure>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dcca735 elementor-align-center elementor-widget elementor-widget-button\" data-id=\"dcca735\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/www.wenglor.com\/a\/121\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Learn more about the application<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3325887 elementor-widget elementor-widget-global elementor-global-7294 elementor-global-22 elementor-widget-spacer\" data-id=\"3325887\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-32dfed3 elementor-widget elementor-widget-text-editor\" data-id=\"32dfed3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h3><strong>The decisive advantage: Clear material selection<\/strong><\/h3><p>Whether it&#8217;s an aluminium fastener under plastic or thin aluminium foil in the conveying process \u2013 the steel environment is practically &#8220;faded out&#8221; while the desired material is reliably detected. This creates a robust solution that can be integrated comparatively easily into existing systems and offers a high level of process reliability. <\/p><h4><strong>Transferable to many applications<\/strong><\/h4><p>Such requirements are by no means limited to pipe production or packaging technology.
