Multiple light beam safety devices
M4000 Advanced

Intelligent and efficient: connection of the muting signals directly on site

Your Benefits

  • The wide scanning range allows the device to be customized according to the application
  • Robust design with a high level of resistance to environmental changes ensures high machine availability, even under special ambient conditions
  • Mounting grooves on three housing sides ensure more mounting flexibility and simplify machine integration
  • Customer-friendly interfaces and status display simplify commissioning and maintenance
  • For 2- and 4-sensor muting, the on-site connection of the muting signals significantly minimizes wiring costs and simplifies commissioning and maintenance
  • Reduced downtime due to 360° visible LED, diagnostics displays and configuration memory in the UE403 muting switching amplifier
