an arm’s length and is valid as a minimum supplement to protect against reaching

4.3.6.3 Height of the scan plane
Overview
If y
ou choose a resolution of 70mm for hazardous area protection, it is not possible to
detect a human leg under certain circumstances. This is because a beam does not hit
the leg. Rather, the beams pass by the sides of the ankle (see figure 29, page 38). If
you mount the safety laser scanner at a height of at least 300mm (height of the scan
plane), the scan plane is at calf height and the leg is detected even at a resolution of
70mm (see figure 30, page 39).
