Nanometer precision absolute 2D position

PreciLabs proprietary 2D absolute position encoding and real-time 2D absolute position decoding techniques (patent pending) enable the reading of the 2D absolute position of a 2D absolute code printed on a surface:


• High Precision (sub-nanometer)

• Very high position refreshment cycle (>100kHZ)

• Large sensor/scale travel speed (200m/s)

• Practically infinite scale dimension (>500e6 km2)

• Best in class error detection and correction

• Scale damage and/or contamination up to 50%

• Highest safety integrity level

• Compensation of static and dynamic tolerances

• Easy, low-cost printing and installation e.g. self-adhesive tapes in arbitrary lengths / segments

• Compact, low-cost, single-ASIC solutions

• Condition monitoring, early detection of failure

• Deformation sensing

• LASER marking reading on shiny steel surface (e.g. hydraulic piston rod)

• Can serve Multi-dimensional, 2-6D absolute position sensing

PreciLabs Aboslute 2D Position Sensors are offered as PreciLabs branded products for system integrators or White Label product to sensor manufacturers. The modularity of the design offers different connectivity protocols and the option to design custom enclosure around the PreciLabs sensor module hardware. For higher volume application, PreciLabs provides a reference design based on PreciLabs position sensing components and firmware.


Application examples:

  • Hydraulic piston position (e.g. forklift trucks, construction machines, mining, etc.)
  • Elevator cabin position
  • Elevator motor angular position (>23bit/revolution (b/rev))
  • Moving Stages 2D-6D position (we can use also the printed 2D code for 3D-6D)
  • Conveyor position in factory automation
  • Assembly lines in factory automation
  • Three dimensional 3D robot / forklift track position for warehouse order preparation system
  • Storage rack position
  • 1D-2D cutting machines (e.g. wood, steel, plastic)
  • Precise crane position
  • Torque sensing
  • Deformation, load sensing, condition monitoring of machine parts, early detection of failure
