Ultrasonic sensors - Long type M18

  • Very large detection range
  • Intuitive setting of the detection range via pushbutton or IO-Link
  • Clearly visible LED for indicating switching status and echo
  • With programmable switching output and scalable analogue output
  • Non-contact detection independent of colour, transparency or surface characteristics of the object
