SICK MLG10A-0740B10801 MLG-2 Measuring Light Grid
Description
MLG10A-0740B10801, part no. 1221116, belongs to the SICK MLG-2 range of measuring automation light grids for object and profile detection. The catalogue summary lists: device version: Pro – Extended functionality; inputs/outputs: 2 x analog + 2 x Q (IO-Link); option: None; beam separation: 10 mm; operating range: 8.5 m.
Understanding the MLG10A-0740B10801 before you specify it
It watches the shadow of an object across many beams, so one device gives height, position or the number of objects passing through. The data sheet gives the beam separation, operating range, detection height and response time.
These determine the smallest object that can be resolved and how fast the line may run. It is described in the operating instructions. Many closely spaced beams give a profile of height or position, while a few beams only indicate presence.

About brand
SICK is the German maker of industrial sensors: photoelectric and proximity sensors, safety laser scanners and light curtains, encoders, distance sensors, code readers and gas analysers. Erwin Sick, an optics engineer, founded it in Munich in 1946, and in 1952 it introduced its first marketable accident-prevention light curtain, which protected press operators by stopping the machine when a hand broke the light beam. The company moved to Waldkirch in the Black Forest in 1956 and is still headquartered there. It is a privately held company, and has been an Aktiengesellschaft (AG) since 1996.

Choosing a SICK sensor
For object detection, the sensing principle comes first. A retro-reflective sensor (WL series) sends light to a reflector and switches when an object breaks the beam; it is reliable over long distances and easy to align. A sensor with background suppression (WTB series) detects an object at a set distance and ignores what is behind it, which suits conveyors with shiny or dark backgrounds. A through-beam pair (WS/WE) gives the longest range and the highest reliability in dust. For transparent bottles and film, use a model built for transparent objects (for example WL12G-3B or WL150-P420). The digits in the code also matter: "P" usually means a PNP output and "N" NPN, and the last digits set the connector or cable. For machine guarding, a safety laser scanner such as nanoScan3 or microScan3 protects an area, while a safety controller such as Flexi Soft combines several safety devices.
Where SICK products are used
In Oman and the GCC, SICK sensors are used in packaging and bottling lines, food and beverage plants, logistics and airport baggage handling, cement and steel plants, ports and cranes, automated warehouses, and on machines built by European OEMs. SICK safety scanners guard robots and automated guided vehicles, and its encoders give position feedback on motors, hoists and conveyors.

Ordering SICK products: what we need
Send the type code and the 7-digit SICK part number from the label (for example WTB12-3P2431 together with its part number). For a replacement sensor, add the output (PNP or NPN), connection (M8, M12 or cable) and sensing distance. For encoders, add the interface (incremental, SSI, PROFIBUS, PROFINET), resolution and shaft type. For safety scanners, tell us the model and whether the existing configuration needs to be kept.
