The LZR®-FLATSCAN 3D SW is a safety sensor designed for swing doors. Using laser time-of-flight technology, its volumetric detection field covers the complete opening area of the door, guaranteeing more comfort and safety to the users. Completely touchless. It prevents any contact with the user by avoiding sudden movements of door leaves. The coverage of the hinge area and the leading edge area is increased to avoid any risk of contact.

If a person or an object is present in the pathway, the door does not make any sudden movements thanks to the 4 laser curtains. Any risk of contact with the door is prevented whatever type of swing door.

The high resolution volumetric curtains of the LZR®-FLATSCAN 3D SW detect fingers and bodies in the entire defined detection area. The hinge area and the leading edge are secured.

Thanks to a third output, the LZR®-FLATSCAN 3D SW also has an activation function, ensuring hygienic and on demand opening of the door. You can choose between creating up to 2 push buttons or using the curtains to activate the door, without the inconvenience of wiring new switches.

The LZR®-FLATSCAN 3D SW offers a hygienic safety solution by avoiding the use of mechanical finger protection.
No maintenance and cleaning is required to fight the spread of bacterias.
