Siemens's Industry Automation Division is producing a new inductive proximity switch for the precise analogue and dynamic measurement of distances from metal objects. The Simatic PXI920 has a compact M12 frame size and a high IP67 degree of protection. It measures object distances from 0 to 3mm at a frequency of 250Hz. Values of between 0 and 10V, proportional to the measured distances of the object, are made available at a voltage output for further processing. The proximity switch can be mounted flush. It is especially suitable for dynamic fine positioning and controlling feeders, for example so-called "dancer controls', which are used for continuous products, such as foils, plastics, paper, sheet metal and textiles.
Simatic PXI920 is suitable for use in a wide range of applications, such as packaging processes, plastic processing machines, and in the manufacture and processing of continuous products. In automated production, analogue distance measurement plays a part in the precise evaluation of wear and fracture, and in making the simple distinction between tool and workpiece. This new inductive proximity switch has advantages over binary proximity switches, especially under difficult environmental conditions. For example, it can detect the presence of swarf and slag before a possible plant failure occurs.
