Natick, MA— Cognex Corp. introduced its new Checker 101 single-purpose sensors at PackExpo International 2004 , Nov. 7-11, at Chicago’s McCormick Place. The firm says its simple-to-use, inexpensive sensors can visually detect the presence or absence of components during the manufacturing process. Cognex plans to begin shipping Checker 101 in 2005’s first quarter.

'Checker 101 is the first member of Cognex's new Checker family of vision sensors. Unlike general purpose vision systems that can be programmed to perform a wide variety of tasks, each model in the Checker family will do only one thing, but it will do it extraordinarily fast and well,' says Dr. Robert Shillman, Cognex's chairman and CEO. 'Checker 101 was designed from the ground up to be far simpler to use than any general purpose vision system. It’s so simple that even first-time users will have it up and running in a matter of minutes. And, because of its low price and ease of use, factory technicians and electricians will find Checker an attractive tool for solving many manufacturing problems that they previously solved, or tried to solve, with photodetectors or other similar devices.

“The market for all presence-sensing devices is in excess of $1 billion annually, worldwide, and, because Checker 101 has a significant price/performance advantage over other means of presence sensing in complex applications, we expect it to garner a significant percentage of that market over time.'

Checking for the presence or absence of multiple items, such as the cap and the label on a bottle, or all of the lugs on a truck wheel, or all of the pills in a blister pack, is one of the most frequent tasks in manufacturing. To ensure product quality in these applications, most manufacturers currently use either a complex system of multiple photodetectors, or they rely on people to perform inspections. Now, with one Checker, manufacturers will be able to inspect 100% of their products at each stage of their production lines. And, because Checker can analyze over 400 images per second, it can keep up with even the fastest manufacturing operations.

Checker's compact design provides illumination, optics, sensor, processor, memory and I/O, all integrated into one industrial-grade package about the size of a cell phone. In addition, Cognex says its unique, patent-pending technology enables Checker to automatically detect when a product is ready to be inspected. Consequently, it doesn't require an external trigger, even for products in continuous motion at high speed, as
