Sick’s new compact Ax20 array sensor is said to deliver high performance web positioning and edge detection. The scanning opto-electronic system offers repeatable automated object detection with a resolution down to 50 micron, allowing precision control of web position even at high operating speeds.
Operating from one side of the web only, the sensor’s measuring range of up to 30mm eliminates the need for fine adjustment, while the visible light spot facilitates accurate alignment, without the need for teach in. These advantages are said to ensure the Ax20 is far more versatile and reliable than conventional fork sensors.
The compact Ax20 requires no reflector, so is easy to locate and mount, and simple to adjust for optimum results. It is immune to high levels of ambient light and reflective or transparent materials.
As well as high speed web detection, the sensor can be used in a variety of applications, including edge detection and thickness measurement of sheet-fed material such as paper and card, even in stacks.
The Ax20 measures just 100mm by 65mm by 50mm thick, but scans a wide area, totaling 30mm, at a range of up to 100mm. The compact size of the sensor unit and its wide scanning capabilities are said to make it ideal for installation in confined spaces.
