The LT was specifically developed for use in elevators, doors and gates. It is very easy to install, cost-efficient and available in the typical monitoring heights. The LT40 complies with the EN81-70 and EN81-20 requirements. Through use of parallel beams, the detection of objects equal to or greater than 50 mm is ensured over the whole monitoring area. It´s fully compatible to its predecessor and can easily be used to modernize existing elevator systems that already utilize DUOmetric products.
