Cognex Corporation, the world’s leading supplier of machine vision systems and vision sensors, has added the Checker 3G series to its award-winning Checker vision sensor product line.
With simple setup, integrated part detection, lighting, I/O and job change all in a rugged IP67 housing, Checker 3G is the easy, reliable and affordable way to verify all products or parts on the line.
With Checker 3G, the user chooses whether to configure the sensor as a presence sensor or measurement sensor. 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”.
Checker is also able to detect and track over 6,000 ppm in varying positions along the production line, overcoming imprecise part positioning and delivering consistent, precisely timed pass/fall results. No other sensor, vision sensor, or vision system can do this.
The new Cognex offering does not require a PC for setup. Instead, the SensorView Teach Pendant, with its unique one-click setup technology, allows the user to set up jobs right on the line and has them running in a matter of minutes. A single teach pendant can be used to set up any number of Checker 3G sensors and can remain connected for real-time application monitoring.
The SensorView Teach Pendant is a compact, rugged, panel-mount display for both the Checker 200 and 3G series of vision sensors. More than just a display, SensorView provides production statistics and a user-definable view of the parts that Checker is inspecting. This enables operators to easily monitor their production process, change jobs, or retrain patterns without a PC.
The key to the simplicity of the Checker is its one-click setup. By simply clicking on the feature in the image that you want to inspect Checker automatically creates a sensor, learns the features attributes and sets the appropriate pass/fail criteria.
The Checker 3G series joins the existing Checker 200 series that features additional I/O, encoder-based part tracking, an industry standard ladder logic editor for custom logic and the ability to inspect smaller features over a larger area. The Checker 3G is currently available.
