Array sensor

The Ax20 array sensor has a high-resolution line array that allows objects to be detected with a repeatable accuracy of 50 µm. It is suitable for detecting edges, inspecting material thicknesses, counting parts or determining positions.

The Ax20’s scanning method of operation results in no supplementary reflector being required. The measurement area can be up to 30 mm wide. Its adjustment is particularly easy due to the visible white light. In addition, the sensor is highly immune to ambient light and supplies precise and reliable results regardless of the reflectivity properties of material surfaces — without any need for teach-in.

With its compact housing and appropriate mounting accessories, the Ax20 offers a high level of installation flexibility. This is as important for applications in packaging machines, in the print and paper sector, or in metal processing; for example, as there are numerous ways in which the measurement values can be used. Typical areas of use include the provision of measurement values for controlling the sides of webs of endless materials such as foils, paper or fleeces. The continuous application of a material, such as a strip of glue applied by a glue applicator system, can be detected and tracked with high precision. The position of, for example, sheets of paper, flat work pieces or electronic cards can be reliably determined with the assistance of the Ax20 and the Ax20 is also suitable for counting the number of parts ejected from a machine, even those passing through the measurement field in free fall.
