Easy, reliable and flexible

The Checker® 4G series of vision sensors 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. Checker 4G models 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.

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

The Checker 4G models also provide additional flexibility through a number of unique features:

  • Industry standard Ladder Logic editor allows for customization of results and eliminates PLC programming
  • EtherNet/IP industrial protocol with RSLogix5000™ Add-On-Profile
  • PROFINET industrial protocol support
  • Image storage to FTP server
  • Remote setup and display through your PC
  • Encoder-based part tracking for variable speed lines
  • Up to four discrete outputs
