Optical linear scale

Product code: “uLMO-xx”

Linear scale ( linear encoder, linear position sensor ) is designed for measurement of linear movements of mechanisms.


Main properties

  • High precision: (0.005mm, 0.001mm)
  • Noise protection: TTL or RS422
  • Aluminum case
  • Measurement length: 100 … 2500mm.


The main application area is measurement of the tool movements

  • Milling machines
  • Lathes
  • Erosive machines
  • Coordinate machines
  • Microscopes, etc.


For display of information about the current position of the tool we offer the Digital readout device “uDR – 1300D”.

Also for measurement of linear movements we offer Magnetic linear scales “uLMM-xx”.
