Cognex has added the Checker 3G series to its award-winning Checker vision sensor product line. With simple setup, integrated part detection, lighting, I/O and job change all in a rugged IP67 housing, Checker 3G is the easy, reliable and affordable way to verify all products or parts on the line. With it the user chooses whether to configure the sensor as a presence sensor or measurement sensor. Presence sensors verify that features are present. Measurement sensors verify that features are the correct height, width and/or diameter. In either mode, there is no limit to the number of part features that a single Checker can “check”. Checker is also able to detect and track over 6,000 ppm in varying positions along the production line, overcoming imprecise part positioning and delivering consistent, precisely timed pass/fall results. No other sensor, vision sensor, or vision system can do this.
