Cognex's Checker 101E directly accepts encoder signals, eliminating the need for a PLC when tracking and rejecting products on variable-speed production lines. Acquiring and processing over 500 images per second, the unit is able to detect and inspect product. If inspection is not required, it can be used to detect and track products for improved process control. The unit offers automatic shift register, enabling it to accurately track up to 4,000 items between the inspection and rejection point. Checker's step-by-step setup is easy to deploy, says the company.
