Safety light curtains
C4000 Advanced

Increase productivity with greater machine safety

Your Benefits

  • Blanking functions enable reliable and safe object detection and thus increase productivity
  • Time-saving alignment and diagnostics by means of 7-segment display
  • Beam coding protects the systems against mutual interference and thus offers a high level of availability
  • The clone plug can duplicate configurations quickly and easily, thus saving time and money
  • Increased flexibility and reduced wiring complexity via cascading of up to a maximum of three systems
  • Convenient configuration anddiagnostics ensure increased availability


Increase productivity with greater machine safety

The C4000 Advanced safety light curtain reliably protects against access into hazardous points and areas. Integrated blanking functions allow objects (such as cables or work tables), but not people, to enter the protective field. Cascading several systems offers the user a high degree of flexibility for the application solution. The restart interlock (RES) and external device monitoring (EDM) functions provide easy machine integration. Various mounting adapters and innovative accessories enable flexible installation. The industry-tested 7-segment display saves time during alignment and diagnostics. The C4000 Advanced, which provides protective field heights from 300 mm to 1,800 mm, offers reliable machine protection up to the highest protection level, PL e.
