Opening, area surveillance and safety sensor for industrial doors
Technology Laser


The LZR®-WIDESCAN sensor uses laser technology, based on analysis of time of flight. By generating 7 tilted laser curtains, the sensor creates a volumetric area in front of the door. One device can carry out 3 functions: opening the door, areas surveillance and safety. More than just a sensor, it improves the comfort and safety of the users and increases the protection of the door.


Volumetric coverage

A matrix of 64 pixels in front of the door enables accurate distance measurement and offers advantages, such as calculation of object dimensions and trajectory.

Door protection

The LZR®-WIDESCAN becomes your doorkeeper. It detects approaching or parked vehicles accurately in order to prevent any contact with the door.

Energy savings

Thanks to the reliability of its presence detection, the sensor reduces the time-lag and guarantees earlier closing of the door. The analysis of trajectory, height and type of object enable filtering out parallel traffic and ignoring pedestrians if desired.

Independent of floor and environment

Laser technology offers a high level of independence when confronted with weather conditions such as rain, snow, fog, etc.
