Page 12: General Information
Attention Laser! This symbol warns of possible danger caused by hazardous laser radiation. The light section sensors of the LES series use a class 2M laser: Viewing the laser output with certain optical instruments, e.g. magnifying glasses, microscopes or binoculars, may result in eye damage.
Page 13: Safety Notices
The protection of personnel and the device cannot be guaranteed if the device is operated in a manner not complying with its intended use. The light section sensors of the LES series are laser distance sensors for presence detection of dimensions of objects using their edges.
Page 14: Working Safely
Adjustments: Do not attempt any adjustments to or alterations of this product. Do not open the protective housing of the light section sensor. There are no user-serviceable parts inside. The glass optics cover is the only aperture through which laser light may be observed on this product. Leuze electronic Technical description LES...
