Cognex has added two high resolution models to its line of Checker vision sensors. The Checker 3G7 features 752 x 480 pixel resolution for high quality inspection of small features and high intensity white LED illumination for optimum image contrast. It 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 don't require a PC for set up, and can be configured quickly using the SensorView teach pendant and One-Click Setup feature.
The Checker 272 offers the same resolution and lighting features as the 3G7 plus a ladder logic editor, encoder-based part tracking, and additional IO. It includes both presence and measurement sensors.
Checker is an inspection sensor that can both detect and inspect parts, eliminating the need for an external triggering device. A single Checker can inspect multiple part features simultaneously, and can track parts of varying position on the line, so there is no need for precise part fixturing. All Checker models feature integrated lighting and rugged IP67 housing.
