Vision sensor directly accepts encoder signals

A Cognex UK product story
Edited by the Engineeringtalk editorial team Mar 23, 2006

Machine vision sensor uses patterns to detect and inspect parts, and directly accepts encoder signals, eliminating the need for a PLC when tracking and rejecting parts on variable-speed lines.

Cognex has introduced the Checker 101E machine vision sensor.

Checker sensors use patterns to detect and inspect parts.

The 101E 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 VP for 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 track accurately up to 4000 parts between the inspection and rejection point".

Acquiring and processing over 500 images per second, it can detect and inspect parts on fast production lines.

If inspection is not required, it can be used to detect and track parts or webs for improved process control.

The step-by-step setup makes it simple for anyone on the factory floor to deploy.
