Using a rotating optical system, these measurements are made on a 190° semi-circular area every 0.25° for a total of 760 measurements per scan.
The device performs 33 scans per second.
The Safety Laser Scanner creates a controlled safety area with a maximum radius of 4 meters and a warning area with a maximum radius of 20 meters. The safe detection of a person inside the safety zone is assured independently from the reflectivity of its clothes or skin.
The shape of the two controlled areas is fully programmable. Therefore, for each of the 760 measurements per scan, the laser scanner will compare
the programmed distance to the measured distance.
If the measured distance is less than the programmed one, this means that an obstacle is inside the safety zone. A stop command will thus be sent to the machine.
