Cognex Corporation's Checker 101 is a simple-to-use and inexpensive sensor that can visually detect the presence or absence of components during the manufacturing process. Checking for the presence or absence of multiple items is one of the most frequent tasks in manufacturing. To ensure product quality in applications such as these, most manufacturers currently use either a complex system of multiple photodetectors or they rely on people to perform inspections.
Now, with a single checker, manufacturers can inspect 100% of their products at each stage of their production lines. And, because Checker can analyze more than 400 images per second, it can keep up with even the fastest manufacturing operations.
