Sick ELG3-1890R121 Overview



Light-grid ELG3-1890R121 Height 930mm/Beam spacing 30mm, Relai Output NO/NC, range 12m

Sick ELG3-1890R121 Description



  • Up to 128 beams
  • Different beam separations 30 mm and 60 mm
  • High functional reserve (gain) for ranges up to 12 m
  • Potentiometer for sensitivity setting
  • Ambient light up to 150,000 lux
  • Tough, aluminum housing
  • PNP/NPN/relay output and a test input
  • Optical synchronization
  • Your benefits

  • Insensitive to ambient light when exposed to direct sunlight, strobe lights, and highly reflective objects, eliminating false trips
  • High functional reserve (excess gain) ensures operation even if it gets dirty, dusty, or misaligned, reducing maintenance costs
  • Efficient and effective way to combine multiple sensors in one housing with one connector
  • Simple commissioning thanks to a larger optical aperture angle and manual fine adjustment option
  • Optical synchronization enables quick installation and cost-effective connection
  • The sensitivity adjustment can be used to detect or ignore translucent materials to reduce production problems
