Pepperl+Fuchs releases SmartRunner family of light-section 2D vision sensors

October 17, 2018 – Pepperl+Fuchs has released its SmartRunner family of sensors, based on a combination of light-section technology and 2D vision, and tailored to the needs of specific applications.

The SmartRunner Matcher is a compact, camera-based light-section sensor that combines both the evaluation process and the interfaces in one device. The device features a specially pre-configured firmware that enables it to specialize in extremely precise profile comparisons.

After initial setup and configuration of the reference profile, the Matcher captures an image of each object’s line profile. Using LEDs and a 2D camera, the SmartRunner Matcher compares the current profile to the taught-in reference profile. When the scanned profile matches the reference profile, the Matcher sends a “good” signal. When the profile deviates from the reference, it sends a “bad” signal.

A 2D vision sensor requires significant object contrasts for it to perform a viable evaluation. In comparison, the Matcher “sees” succinct shapes and edges, as the projection of a sharply defined laser-line enables clear and unique evaluations. The company says this makes the system noticeably less sensitive to disruptive extraneous light, reflections, and the influence of various object colors and surfaces.

In addition to the Matcher, Pepperl+Fuchs also introduces the SmartRunner Detector. The focus of this light-section sensor is on protecting expensive components and increasing machine availability. It detects even the smallest unauthorized parts, overlapping and overhangs. The Detector reliably identifies objects with a minimum size of 0.25 mm in a trapeze-shaped measuring range with a width of 350 mm at a maximum range of 700 mm.

The SmartRunner Detector evaluates both the laser line on the object as well as the background for the most reliable results. The integrated camera also makes it possible to record images in order to document the complete process and assure top quality control. The recorded error images can be uploaded remotely, preventing trips to the factory floor and allowing easy monitoring of difficult-to-access machine areas. The high-performance LEDs supply consistent, brightly lit images. Parameterization through Data Matrix control codes is also possible.
