une source de lumi\u00e8re infrarouge ou laser. En r\u00e8gle g\u00e9n\u00e9rale, une barri\u00e8re immat\u00e9rielle se compose d'un \u00e9metteur et d'un r\u00e9cepteur (ou d'un r\u00e9flecteur). De nombreux faisceaux de lumi\u00e8re sont \u00e9mis de l'\u00e9metteur vers le r\u00e9cepteur (ou le r\u00e9flecteur), et lorsque la lumi\u00e8re est bloqu\u00e9e par un objet, la machine cesse de fonctionner. Les barri\u00e8res immat\u00e9rielles de s\u00e9curit\u00e9 sont largement utilis\u00e9es dans diverses machines telles que les \u00e9quipements hydrauliques et les ascenseurs, les machines de cisaillement ou les presses lourdes, etc.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-863333a elementor-widget elementor-widget-heading\" data-id=\"863333a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Qu'est-ce qu'une barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 de type 2 ?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-856397b elementor-widget elementor-widget-text-editor\" data-id=\"856397b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">La barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 de type 2 est un dispositif de protection photo\u00e9lectrique peu co\u00fbteux qui est principalement utilis\u00e9 pour prot\u00e9ger les mains qui ne sont pas en contact avec le sol. <\/span><span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/www.motioncontroltips.com\/what-is-external-device-monitoring-how-does-it-relate-to-machine-safety\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Surveillance des dispositifs externes (EDM)<\/span><\/a><\/span><span style=\"font-weight: 400;\">Il est con\u00e7u pour les situations et les machines pr\u00e9sentant des dommages mod\u00e9r\u00e9s ou mineurs.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-946cdda elementor-widget elementor-widget-heading\" data-id=\"946cdda\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Qu'est-ce qu'une barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 de type 4 ?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e12c807 elementor-widget elementor-widget-image\" data-id=\"e12c807\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"768\" height=\"384\" src=\"https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine-768x384.jpg\" class=\"attachment-medium_large size-medium_large wp-image-13187\" alt=\"Barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 utilis\u00e9e dans les machines \u00e0 cisailler\" srcset=\"https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine-768x384.jpg 768w, https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine-300x150.jpg 300w, https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine-600x300.jpg 600w, https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine-64x32.jpg 64w, https:\/\/lorentzzi.com\/wp-content\/uploads\/2024\/01\/Safety-light-curtain-used-in-shearing-machine.jpg 1024w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4af27e4 elementor-widget elementor-widget-text-editor\" data-id=\"4af27e4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\"><span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/lorentzzi.com\/fr\/products\/proximity-sensor\/safety-light-curtain\/type-4-safety-light-curtain-ple-rating-for-finger-protection\/\">Barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 de type 4<\/a><\/span> est sp\u00e9cialement con\u00e7u pour les occasions n\u00e9cessitant un niveau de protection \u00e9lev\u00e9.
