SICK MLG-2 Prime

Figure 12: Cross-beam function
A minimum dist
ance between the sender and the receiver is required for the cross-
beam function. The minimum detectable object size depends on the position of the
object within the detection area. Detection of the smaller minimum detectable object
size is therefore only possible in the central area (b) of the detection area.
•
The cross-beam function is only useful for object detection (NBB ≤ 1). For other
applications (height classification, object recognition, etc.), the results of the paral‐
lel-beam function are used.
•
Use of the cross-beam function increases the response time.
•
With the cross-beam function, a minimum distance needs to be maintained
between sender and receiver. The minimum distance depends on the aperture
angle of the light grid.
•
For moving objects for the cross-beam function, the minimum detectable object
depends on the speed of the object.

3.7 Operating reserve
The operating reserve defines the operational safety before contamination, vibrations,
misali
gnment, temperature fluctuations, etc. cause the MLG-2 to produce incorrect
measurements.
The MLG-2 is subject to a certain level of contamination depending on its environment
and application. In principle, the MLG-2 must be cleaned regularly and a teach-in
should be carried out after cleaning.
