Cognex has introduced the Checker 101E, a new model in its Checker family of sensors. Checker sensors use patterns to detect and inspect parts, providing high degrees of reliability. Checker 101E offers all the simplicity and power of the original Checker 101, plus it directly accepts encoder signals, avoiding 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.
