Sensing Coils IRT: Features

  • Typical application areas: Tube processing machines (Straightening, Pilgering), tube feeding by mandrel bars
  • High operational reliability under difficult conditions
  • Position and orientation independent object detection
  • Insensitive to non-metallic contamination
  • Insensitive to environmental influences like temperature and humidity
  • Response sensitivity largely constant in the entire sensor area
  • Detection of even small objects (ferromagnetic bar material with ø1.25mm)
  • Available in various dimensions
  • Extremely robust design, protection class IP65
  • Coil body milled from durable solid plastic
  • Sensing coil sealed in coil body
  • Up to 3m long connection cable between IRT and IRV

Control Unit IRV20: Features

  • Automatic compensation of environmental metal masses
  • Automatic compensation of environmental fields
  • Automatic adjustment of the optimum response sensitivity related to the immersion depth of the material in the coil
  • Adjustment remains stored after power-off
  • High operational reliability under difficult conditions
  • Isolated optocoupler switching outputs with high load rating (30V/100mA)
  • Isolated optocoupler switching inputs
  • Robust metal housing, protection class IP65
  • Supply voltage: 24V DC or 24V AC
