Sensing range
The detection area is determined by the monitoring height and the sensing range of the
li
ght g
rid. 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.
3.4.3 MLG-2 Prime synchronization
The sender and receiver synchronize with each other optically, so no e
lec
trical connec‐
tion is necessary. For this reason, either the first or last beam of the MLG-2 Prime must
always be made. If both beams are blocked, no measurements can be taken. As soon
as one of the beams is made again, the sender and receiver synchronize once more.
However, this can take up to seven scan cycles (see "Scan time", page 18).

Beam separations
In or
der t
o achieve different levels of measurement accuracy, the MLG-2 is available
with different beam separations.
