UDC-18GM-400-3E1 Double sheet sensor

Key Benefits at a Glance

  • Ultrasonic system for reliable detection of no, one, or two overlapping sheet materials, preferably papers
  • No teach-in required
  • Function indicators visible from all directions
  • Insensitive to printing, colors, and shining surfaces
  • Material weight from 10 g/m2 up to over 2000 g/m2
  • Very wide material spectrum, finest papers up to thin sheet metals as well as plastic- and metal foils
  • Perpendicular or inclined sensor mounting relative to the sheet plane possible
  • Programmable
