Sick are presenting the new Ax20 array sensor at the at the SPS/IPC/DRIVES fair. “Line-for-line further ahead” is what the new Ax20 array sensor promises. The sensor has a high-resolution line array with which the most varied of objects can be detected with a repeat accuracy of 50 µm. Whether for detecting edges, inspecting material thicknesses, counting parts or determining positions – the rapid line sensor, offering a hitherto impossible level of compactness and flexible mounting, opens up new automation solutions.
The Ax20 array sensor’s scanning method of operation, as a result of which no supplementary reflector is required, is a major advantage. The measurement area can be up to 30mm wide. Its adjustment is particularly easy with the visible white light. In addition, the sensor is immune to ambient light and always 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 array sensor 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 the numerous ways in which the measurement values can be used. Typical areas of use for the scanning line sensor include the provision of measurement values for controlling the sides of webs of endless materials such as foils, paper or fleeces, whose passage through a machine can be regulated according to the signals transmitted through the analogue 4-20 mA output.
Detection can take place both through the edge of the web and on the basis of a line on the material. The continuous application of a material, e.g. a strip of glue applied by a glue applicator system, can be detected and tracked with maximum precision.
The Ax20 array sensor also offers interesting opportunities in the area of position detection. The position of, for example, sheets of paper, flat workpieces or electronic cards can be reliably determined with the assistance of the Ax20 array sensor.
