•
The object blocks access to the hazardous area. Lateral interruption in the protec‐
tive field is not possible.
•
Smart Box Detection may only be used in applications where it is ruled out that
people or body parts can be recognized as valid objects, e.g. due to their work
clothes or due to deliberate manipulation of the protective device.
Functionality
The protective device detects objects that cast a rectangular shadow without gaps
when passing through.
If, on the other hand, other objects, especially persons, enter the protective field, the
protective device detects the deviation from a valid object. The dangerous machine
state is stopped.
Figure 25: Left: Rectangular shadow without gaps. Right: Shadow with gaps.
If Smart Box Detection is configured, the protective field always remains active. Inter‐
ruption in the protective field above a valid object is reliably detected by the protective
device and the dangerous machine state is stopped.

Object properties
Overview
Smart Box Detection allows geometrically uniform objects to pass through the protec‐
tive field that have a certain minimum size.
Objects in reality often have odd object edges or are damaged, e.g. the transport box
is torn or dented. Smart Box Detection therefore also allows objects whose upper and
lower and lateral object edges are within a certain tolerance zone (increased availability
of the system).
