Safety light curtains, approach at a particular angle α
If α ≥ 30°, see perpendicular approach
If α < 30°, see parallel approach
Hbottom beam ≥ 15 * (d - 50 mm)
Required d ≤ (Hbottom beam /15) + 50 mm
The resulting S is applied to the beam which is located farthest from the danger zone. This beam can be configured at a maximum height of 1000 mm over the reference plane.
Heights > 300 mm are considered to be possible for an adult to crawl under.
