LAK

Absolute optical path encoder

High traversing speeds of up to 10 m/s, various serial interfaces,
resolution as fine as 78 nm, and many other features

The LAK Series catapults absolute measuring into a new dimension. The fusion of incremental and absolute technology in combination with the EPIFLEX sensor module provide this encoder its outstanding features.

  • Linear absolute encoder with ultra small dimensions
  • High resolution up to 78 nm
  • High traversing speed up to 10 m/s
  • Very low weight of the scanning head
  • Automatic signal adjustment after mounting possible with a high number of analysis options via ABSOFLEX software
  • Two absolute tracks and two incremental sensors ensure high contamination immunity
  • Special Kit version available
Precise positioning

High signal quality as well as fast travel speeds due to a novel sensor design with combined absolute and incremental sensing

Save money

Reduced cost of production and lower encoder prices thanks to standardized components

High control dynamics

High control dynamics due to short calculation times
