Increase speed and positioning accuracy, even around corners, with the OLM. 

   Web Part Container
The OLM optical linear measurement sensor determines its absolute position using a bar code strip mounted along the length of travel – up to 10 km. The bar code strip can be placed along a curve, incline, decline or straight line. The OLM is used for high speed, high precision positioning of overhead cranes, rail and transfer cars, and other vehicles. The OLM measures the right position every time - even if the path is blocked by another vehicle.

  • Positions vehicles within 0.1mm out to 10km
  • Works in freezers down to -30°C and steel factories up to 60°C
  • Longest runtime of any positioning sensor - its four LEDs and CMOS camera last twice as long as lasers and rotating mirror technology used in competitive sensors and positioning methods


  • Increase speed and positioning accuracy - reach positions faster with millimeter accuracy
  • Non-contact solution helps ensure longer use and reliable measurement
  • Measure along a straight line, curve, incline and more, providing more flexible measurement options
  • No internal moving parts and resistance to shock and vibration, increases uptime
  • Fast installation and commissioning,  reduces start up time


  • Overhead conveyors and electric monorails – position each within 1mm of the target. Because the exact location of each vehicle is known, throughput is increased and collisions are avoided.
  • Elevators for vertical positioning – horizontal positioning of the OLM keeps debris from blocking optics and 100% solid state LEDs and CMOS elements last twice as long as laser and wiredraw/cable solutions. High speed 0.1mm resolution output results in faster moves, more trips per hour and no over or under shooting and throughput destroying corrections.
  • Freezer areas – SICK’s technology allows these sensors to operate in temperatures as low as -30° C without any additional heaters or protective housings – something most sensors cannot handle due to laser and electronics limitations.
