The height of the protected area
It is important to distinguish between “Height of the sensitive area”
and “Height of the controlled area” (see Fig.2).
- The height of the sensitive area is the distance between the
lower and the upper limits respectively of the first and the last
lens.
- The height of the controlled area is the effectively protected
area. It delimits the area where an opaque object with larger or
equal dimensions respect to the resolution of the safety light
curtain may certainly cause the interruption of a beam.

The safety distance
It is important to carefully calculate the distance between the point
where the safety device will be placed and the possible danger
associated with the machine to be protected (
see section 2
“Installation mode”
for
the calculation of the safety distance).
