3.4.2 Measurement principle
Provided no object is located between the sender and receiver elements, the light
beams from the sender elements will hit the receiver elements.
If an object is located between the sender and receiver elements, the light beams will
be blocked, depending on the size of the object.

Sensing range
The detection area is determined by the monitoring height and the sensing range of
the light grid. The monitoring height is determined by the beam separation and the
number of beams. The sensing range of the light grid is the distance between sender
and receiver.

Beam separations
In order to achieve different levels of measurement accuracy, the MLG-2 is available
with different beam separations.
