From pattern detection to rapid position identification: SICK's PS30 pattern sensor for increase flexibility and reduced material consumption

SICK's new PS30 sensor is a scanning opto-electronic sensor for rapid and precise position identification and presence detection for labels, packaging materials, or tubes. The PS30 is able to detect complex patterns even when objects are moving at high speeds of up to 10 m/s. Based on the principle of operation of a line sensor, it delivers a stable switching signal. The PS30 is primarily used in the packaging industry.

Distinctive taught-in patterns in an image are used as a reference for the subsequent reliable detection and positioning of objects; special reference marks are not necessary. Increased design freedom, reduced material consumption, and effective process control are the advantages. Commissioning the sensor is a quick and user-friendly process which can be completed on the control panel, in the SOPAS configuration software, or via the machine's HMI. Engineering tools for automated format changes and visual diagnosis are available. Formats can be changed quicker and more easily, thus saving time and money.

Increased flexibility

The PS30 is an incredibly flexible solution which responds to trends in the packaging industry toward ever more complex and unusual labels. Offering unrestricted design freedom, the PS30 impresses not only when used on endless tracks – it also delivers outstanding results when detecting patterns on individual objects. Labels can be positioned securely without a print mark. Significant and distinct image areas are analyzed in order to ensure reliable pattern detection – an analysis of the entire image is not necessary. This results in a very fast response time and precise position identification even at high speed. Furthermore, less material is needed for labels when using the PS30, because significant material overlap is no longer necessary to cover the print mark.

SICK is one of the world’s leading producers of sensors and sensor solutions for industrial applications. Founded in 1946 by Dr.-Ing. h. c. Erwin Sick, the company with headquarters in Waldkirch/Germany ranks among the technological market leaders. With more than 50 subsidiaries and equity investments as well as numerous agencies, SICK maintains a presence all around the globe. In the fiscal year 2015, SICK had more than 7,400 employees worldwide and achieved Group sales of just under EUR 1.3 billion.
