Cognex Corp. has added two new high resolution models to its line of Checker vision sensors. The Checker 3G7 features 752 x 480 pixel resolution for better inspection of small features and high intensity white LED Illumination for optimum image contrast. The Checker 3G7 can be configured as either a presence or measurement sensor, and can detect and inspect up to 800 parts per minute. All Checker 3G models require no PC for set up, and can be configured in a matter of minutes using the SensorView teach pendant and One-Click Setup feature.
The new Checker 272 offers the same resolution and lighting features as the 3G7 plus a ladder logic editor, encoder-based part tracking and additional IO. The Checker 272 includes presence and measurement sensors.
Checker is the only inspection sensor available today that can detect and inspect parts, eliminating the need for an external triggering device, according to the company. All Checker models feature integrated lighting and rugged IP67 housing.
