Cognex Expands Inspection Capabilities of Checker Vision Sensors

Model 252 adds pass/fail inspection of height, width, and diameter

Cognex Corporation (NASDAQ - CGNX), the world's leading supplier of machine vision systems and vision sensors, has expanded its Checker vision sensor product line with the Checker® 252 model. The 252 includes 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.

Key to the simplicity of the Checker 252 is its One-Click Setup.  By simply 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.

“With its unique screen caliper, the Checker 252 makes pass/fail measurement verification simple and reliable” said Pascal Dorster, Vision Sensors Business Unit Manager. “Manufacturers in many 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.”

As with other Checker models, the 252 is available with the Cognex SensorView 350, a compact, industrial, panel-mount display. The Checker 252 will be available in November, 2008. For more information, please visit
