Special devices, customer-specific settings or no results at all
In the following cases, please contact your SICK AG sales office:
■Your MLG-1 is a special device: MLGx-xxxxxxxxSxx (example:
MLGx2-1180F822S01)
■Your MLG-1 has customer-specific settings: MLGx-xxxxxxxxKxx (example:

2 Advantages of the MLG-2 compared to the MLG-1
The MLG-2 offers the following advantages over the MLG-1:
■Able to detect smaller objects (high-resolution mode)
■Improved detection of transparent objects thanks to “Transparent mode”
■Improved ambient light immunity due to the smaller aperture angle
■Better able to adapt to the environment and the application thanks to a variety of
operating modes
■Shorter response times and minimum presence time
■Smaller minimum distances when mounting multiple light grids
■Flexible mounting of removable fieldbus module (no blind zone)
■Removable fieldbus modules that can be ordered separately
■Control panel for easy commissioning without a PC
■IO-Link interface V.1.1
■Easy configuration with the SOPAS configuration software via an Ethernet interface
■Configuration options for multiple applications (measuring tasks)
For additional information, see the relevant operating instructions.
2 ADVANTAGES OF THE MLG-2 COMPARED TO THE MLG-1

3 Response times
As the MLG-2 offers shorter response times, you may have to adjust the PLC configura‐
tion. Alternatively, you can also set a digital output delay for the MLG-2. See the relevant
MLG-2 operating instructions.

The response time depends on the beam function and on which basic function is
selected.
In the case of the cross-beam function, multiply the response time in the diagram by 2.
