Safety light curtains
C4000 Advanced ATEX II 3G/3D

Total flexibility – even in explosive environments

Your Benefits

  • ATEX II 3G / 3D for use in 2/22 zones
  • Large sensing range up to 21 m and sufficient power reserve for use in paint finishing lines, for example
  • 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
  • Quick and easy commissioning by means of pre-configuration of the systems or clone plug
  • Convenient configuration and diagnostics ensure increased availability


Total flexibility – even in explosive environments

The C4000 Advanced ATEX II 3G/3D safety light curtain is a cost-effective, reliable solution that safeguards hazardous points and areas, even in potentially explosive atmospheres. Functions such as the restart interlock (RES) and external device monitoring (EDM) 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. Plus, the C4000 Advanced ATEX II 3G/3D safeguards areas with up to an 1,800 mm protective field height.
