Checker 252 verifies height, width and diameter and finds part feature edges with a click

Cognex has expanded its Checker vision sensor product line with the Checker 252 model. The 252 offers all inspection capabilities of the award-winning Checker vision sensor family, plus additional software sensors that verify height, width, and diameter and deliver reliable pass/fail results on high-speed production lines. The Checker 252’s One-Click Setup facility means that when the operator simply clicks on the centre of the part feature, 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 automatically. “With its screen caliper, the Checker 252 makes pass/fail measurement verification simple and reliable,” said Pascal Dorster, vision sensors business unit manager. “Manufacturers in industries, such as automotive and packaging, can now verify dimensions of parts with very low contrast edges and solve a wide range of measurement verification tasks not possible with photoelectric sensors.”
