Laser distance measurement sensors

The laser distance measurement sensors of the LDM series measure distances between themselves and any solid surface, without contact. By doing so, accuracies of a few millimeters are achieved. With their robust design, the LDMs can be used for a wide range of applications, under tough industrial conditions and over a long period of time.

 

Advantages

 

  • wide distance ranges
  • high accuracy
  • easy integration
  • made for industrial applications
  • robust and reliable
  • lifetime of more than 10 years in industrial environments
  • OEM modules available for integration into own products
