NO PLC REQUIRED FOR NEW COGNEX CHECKER SENSOR Checker 101E simplifies part tracking and rejection on variable-speed production lines Natick, MA, March 22, 2006—Cognex Corporation (NASDAQ - CGNX), the world's leading supplier of machine vision sensors, today announced CheckerTM 101E, a new model in the revolutionary Checker family of sensors. Checker sensors are the first and only sensors in the world that use patterns to detect and inspect parts, providing unmatched reliability. Checker 101E offers all the simplicity and power of the original Checker 101, plus it directly accepts encoder signals, eliminating the need for a PLC when tracking and rejecting parts on variable-speed production lines. “The simple-to-use Checker 101 sensor radically changed the way sensor users detect parts or part features, eliminating the complex wiring, mounting, ladder logic programming, and precise part handling required when using multiple photoelectric sensors,” said Brian Phillips, Cognex Vice President, Expert Sensors. “By directly accepting encoder signals, the Checker 101E eliminates the cost and complexity of a PLC for part tracking and rejection on

variable-speed lines. Unlike the shift register of a PLC, which requires programming, Checker’s shift register is automatic, enabling it to accurately track up to 4,000 parts between the inspection and rejection point.” Acquiring and processing over 500 images per second, Checker is able to detect and inspect parts on the fastest production lines. If inspection is not required, Checker can be used to detect and track parts or webs for improved process control. Checker’s step-by-step setup makes it simple for anyone on the factory floor to deploy. The Checker 101E is available now.
