Vision sensor
Checker® 4G series COGNEX

The Checker® 4G Series of vision sensors offers unmatched performance and flexibility to solve even the most difficult applications. The Checker® 4G Series offers the same powerful and easy to use setup Checker is known for plus Ethernet networking for remote setup and monitoring, PLC communication through EtherNet/IP and PROFINET and the ability to save images of every inspection to an FTP server. Like all Checker vision sensors, the 4G Series integrates lighting, optics, camera, processor and I/O in an industrial IP67 housing—all in a package small enough to fit into the tightest of spaces.

Checker vision sensors offer extremely reliable part detection and inspection unattainable with photoelectric sensors, because they:

Use Cognex patented part detection technology to eliminate the need for an additional sensor to determine if the part is present.
Inspect multiple part features simultaneously with a single Checker yielding simple pass/fail results.
Overcome varying part positions which eliminates the need for costly fixturing by finding and inspecting your part.
Empower the factory floor to solve problems through our simple four-step process and our One-Click Setup™ for inspections. Even a first-time user can have it up and running in minutes–without training.

Choose your own configuration when you need it. In any mode, Checker can perform multiple “checks” on each product you manufacture.
