The DW-FLATSCAN3D uses volumetric laser technology to create an extremely accurate and reliable safety solution for automated swing doors. This sensor employs lasers and 'time of flight' technology, rather than traditional infrared detection. Generating a high resolution volumetric laser curtain, DW-FLATSCAN3D allows the door to work as a virtual presence detection system. This ensures that the door only moves when the whole pathway is clear.
