Inductive proximity switch for dynamic fine positioning and control

04.03.2009
Siemens´s Industry Automation Division has produced a new inductive proximity switch for the precise analog 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 3 millimeters at a frequency of 250 hertz.


Values of between 0 and 10 volts, 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.

The 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, analog 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.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
