The Cognex Checker 252 vision sensor offers expanded inspection capabilities. Model 252 includes all inspection capabilities of the Checker vision sensor family, plus additional software sensors that verify height, width, and diameter as well as deliver pass/fail results on high-speed production lines. Checker 252 also features one-click setup. By clicking on the center of the part feature to be inspected, an image of a familiar caliper appears and locks on the edges of the part feature, sets the minimum and maximum thresholds, and learns edge polarity—all automatically. Suitable for use in the automotive industry, the model 252 can verify dimensions of parts with very low-contrast edges and solve a wide range of measurement verification tasks.
