Selecting a Measurement Sensor

Stroke and Positioning

It's possible to measure stroke and position using non-contact or contact-based measurement. The optimal choice will depend on the target's travel speed and distance, as well as the accessibility of the desired measurement area. Contact your nearest sales office with any questions.

Confocal Reflection Method
CL Series
CL Series

These sensors measure the stroke distance of a target using optical reflection. Any type of material can be detected, including transparent glass such as a lens or opaque resins.

Key Points for Selection

  • High-accuracy measurement of target regardless of color, transparency, or shape
  • Ultra-compact and lightweight for easy installation
  • Coaxial measurement eliminates blind spots to measure areas difficult to access
CL-3000 Series
Confocal Displacement Sensor
CL-3000 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.

Key Points for 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.

Key Points for Selection

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