Selecting a Measurement Sensor

Stroke and Positioning

Depending on the target's stroke amount, either non-contact-type measurement or contact-type measurement is possible. Various types can be suggested according to the target's travel speed and travel distance. Contact your nearest sales office with any questions.

Triangulation Reflection Method
LK Series
LK Series

Using optical reflection, these sensors measure the stroke distance of a target. Even transparent targets such as lenses and opaque objects such as resins can be detected.

Point of selection

  • Target selection not determined by transparency/opacity or color
  • Non-contact measurement possible
  • Small beam spot and high speed
LK-G5000 Series
Ultra High-Speed/High-Accuracy Laser Displacement Sensor
LK-G5000 Series
Spectral Interference Method
SI Series
SI Series

The stroke amount is measured using measurement instruments that enforce the spectral interference method.
Sensor heads are as small as φ2 mm, allowing measurement even in narrow locations is possible.

Point of selection

  • Ultra-high accuracy with 1 nm resolution
  • Unaffected by ambient temperature
SI-F Series
Spectral Interference Laser Displacement Sensor
SI-F Series
Contact-Type
GT Series
GT Series

This method measures a target's stroke amount. Adopting a new "scale shot system" principle, the GT2 Series is capable of high-precision measurement without tracking errors or speed errors.

Point of selection

  • Target selection only determined by solidity
  • High-precision measurement possible
GT2 Series
High-Accuracy Digital Sensor
