These devices scan their environment using a quickly-rotating laser measurement beam. This allows them to detect objects even at long distances. With an opening angle of 190° and a measurement distance of up to 65 m, the laser scanner can monitor an area of one hectare. Object detection occurs in parallel in up to 4 detection fields. Convenient configuration software RODsoft permits the parameterization of 8 detection field pairs and 4 detection fields. The status output takes place via a serial interface and an optional warning output. Should service be necessary, the device can be swapped out and put back into operation extremely quickly thanks to the ConfigPlug configuration memory.
