Low-cost presence and measurement sensor works remotely

Cognex Corporation has added the Checker 4G Series to its line of vision sensors. The new sensor adds Ethernet networking for remote setup and monitoring capabilities, PLC communication through EtherNet/IP and PROFINET, and the ability to save inspection images to an FTP server, and all for less than $1,000.

Checker 4G allows the user to configure the sensor as a presence sensor or measurement sensor to inspect and error proof the manufacturing process. Presence sensors verify that features are present. Measurement sensors verify that features are the correct height, width and/or diameter. In either mode, there is no limit to the number of part features that a single Checker can "check". With patented part detection technology, Checker sensors are also able to detect and inspect over 6,000 parts per minute in varying positions along the production line. No other sensor, vision sensor, or vision system can overcome imprecise part positioning while delivering consistent, precisely timed pass/fall results according to the company.-mpweditorial@ubm.com
