Your Benefits

  • Flexibly expandable light grid system: Up to 60 sensors can be cascaded and controlled centrally via the FlexChain host
  • Ready for operation immediately: The sensors are identified and taught in at the push of a button
  • Optimum measurement certainty thanks to sequential sensor cycling without mutual interference
  • Highly flexible positioning of through-beam photoelectric sensors, photoelectric retro-reflective sensors, photoelectric proximity sensors and light grids at any distance or in any position
  • High process stability thanks to extensive diagnostic function
  • High flexibility due to logic configuration in the host and the IO-Link, CANopen and RS-485 interface variants



The FlexChain is a flexibly configurable light grid thanks to the sequential connection of several sensors. There is no need for long connection cables or complex wiring. By pressing a button on the FlexChain Host, the sensors can be addressed and taught-in automatically, meaning the system is immediately ready for use. Different sensor technologies can be combined and freely arranged: Through-beam photoelectric sensors, photoelectric sensors. The raw sensor data is evaluated via the FlexChain Host with integrated logic modules or forwarded directly via IO-Link, CANopen, RS-485 or I/O signals. Detailed diagnostic information ensures optimum process stability and measurement certainty during operation.
