Figure 36: MDO: Example of a light grid with 10-mm beam separation and the set 9x cross-beam
option
For the 9x cross-beam option, the MDO for a device with 10-mm beam separation is
equal to 8 mm in the MDO3 range and 6.5 mm in the MDO2 and MDO4 ranges. In the
MDO1 and MDO5 range, the MDO is 15 mm, as in parallel-beam operation.
It should be noted that the 9x intersection is achieved only in the middle region of the
vertical light grid length (from beam 4 to beam N-3). After that, the cross-beam option
decreases by one option per beam.
The MDOx ranges are relative indications. In this example, if the light grid has a working
distance of 1,000 mm, the MDO3 range is 120 mm and MDO2 and MDO4 ranges are
330 mm each. If the light grids are spaced twice, the MDOx range is also doubled.
The higher the set cross-beam option, the greater the range of better resolution due
to crossed beams between the sender and receiver (MDO2 – MDO4). The table below
contains the MDO data depending on the set cross-beam option and the beam separa‐
tion of each individual range.
