Ultrasonic sensor M18 short design

Rate this product
  • Can be used as a diffuse reflection sensor or retro-reflective sensor
  • Reliable measurement regardless of transparency, gloss, surface characteristics and material colour
  • Resistant to contamination, moisture, dust and mist
  • Stainless steel housing material (DIN 1.4404) or plastic (PBT)
  • Two different operating ranges up to 1.2 m
  • Switching output NPN/PNP, analogue output
  • Parameterization via programming cable
  • Temperature compensation

Thanks to the compact and robust design, the U*18S is the optimum solution for difficult application conditions. In combination with selectable output forms, the space-saving version offers flexibility for measuring and switching applications.

In addition, this series can be used either as a diffuse reflection sensor or as a retro-reflective sensor.
