Safety light curtains
M4000 Advanced Curtain

On-site connection of the muting signals and high resolution

Your Benefits

  • High resolution (14 mm/30 mm) reduces the safety distances for access protection – both with and without muting
  • The robust housing and high power reserve enable reliable use, even in harsh ambient conditions
  • Mounting grooves on three housing sides ensure more flexibility in the installation and simplify machine integration
  • User-friendly interfaces and status indicators facilitate commissioning and maintenance
  • On-site connection of the muting signals on the UE403 muting switching amplifier minimizes the time spent laying cables and facilitates commissioning procedures and maintenance
  • Reduced downtimes through all-around-visible LED and diagnostics displays as well as configuration memory in the UE403 muting switching amplifier


On-site connection of the muting signals and high resolution

The M4000 Advanced Curtain safety light curtain, together with the UE403 muting switching amplifier, provides an efficient solution for conventional muting applications involving automatic material transport. It is ideal for applications that require high resolutions due to a short safety distance. The simple configuration via PC and the local connection of the muting signals ensure maximum availability. Various mounting adapters and innovative accessories enable flexible installation of both the device and muting sensors. Integrated functions, as well as status and diagnostics information, ensure quick commissioning and prevent unnecessary machine downtime. The modular design allows the coordination of device features and provides a cost-effective solution for higher-level machine safety. Lastly, sens:Control devices, accessories, and service concepts provide a complete packaged solution designed specifically for the application.
