Safety light curtains
M4000 Advanced Curtain

Your Benefits

  • The high resolution (14 mm / 30 mm) reduces the safety distances for access protection, with and without muting
  • The rugged housing and high power reserve enable reliable use, even in harsh ambient conditions
  • Mounting grooves on three sides ensure greater mounting flexibility and facilitate integration with the machine
  • Customer-friendly interfaces and status indicators facilitate commissioning and maintenance
  • On-site connection of the muting signals to the UE403 muting switching amplifier minimizes cabling work and simplifies commissioning and maintenance
  • Reduced downtime due to all-around-visible LED and diagnostics displays as well as the configuration memory in the UE403 muting switching amplifier


Together with the UE403 muting switching amplifier, the M4000 Advanced Curtain safety light curtain forms an efficient solution for conventional muting applications with automated material transport. It is particularly well suited when high resolutions are required due to short safety distances. Simple configuration via PC and the on-site connection of the muting signals ensure maximum availability. Various mounting adapters and innovative accessories enable flexible installation of the device and muting sensors. Integrated functions as well as status and diagnostic information enable quick commissioning and minimize unnecessary machine downtime. The modular design allows the specific coordination of device features to requirements and provides an economical solution for high machine safety. In addition, sens:Control devices, accessories, and services complete the product offering and form packaged solutions designed specifically for industrial environments.
