Area Laser Light Barriers Used for Measuring Purposes
In addition to an analog output, 2 switching outputs are available as PNP N/O contacts. The switching points can be positioned anywhere along the band. The 1-10 V analog signal changes continuously depending on how much of the laser line is covered. The size of the object being measured is determined by the level of coverage.
Common areas of application of this laser light barrier include the selection of objects according to size or position, diameter testing in winding processes, monitoring thread breakage, entry speed reduction, and aerosol testing.
