Enhanced Vision Sensors

Dec. 1, 2008
The Checker 252 vision sensor possesses the inspection capabilities of the vendor’s previous Checker sensors and adds additional software features that verify height, width and diameter, and are designed to deliver reliable pass/fail results on high-speed production lines.
Key to the simplicity of the Checker 252 is its one-click set-up. 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 automatically. With this screen caliper, says the vendor, the sensor simplifies pass/fail measurement verification. The Checker 252 is said to verify dimensions of parts with very low-contrast edges and solve a range of measurement verification tasks not possible with photoelectric sensors.Cognex Corp.www.cognex.com877.264.6391
