Together with the M4000 Advanced multiple light beam safety device, the UE403 muting switching amplifier forms an efficient solution for remote, conventional muting applications with automated material transport. Its integrated functions, which can be configured easily via the RS-232 interface using a computer, and the simple on-site connection of the muting signals and control switches to the UE403 muting switching amplifier make it possible to implement access protection solutions with muting with maximum availability.


  • Connection of 2 to 4 muting sensors, external muting lamp, reset and override control switch, belt stop signal
  • Functions: Concurrence monitoring, monitoring of the total muting time, sensor gap monitoring, sensor testing, partial blanking, end of muting via the ESPE, integrated override
