Digital Contact Sensor

Product outline

ULE-50 is a digital contact sensor designed for use with FS2000 and F381A-LDI.

  • 50mm stroke for various workpieces.
  • Robotic cable for installation on moving parts.
  • Ideal for use with FS2000,F381A-LDI indicator.
  • By using it with a load cell and “FS2000,F381A-LDI” force vs. displacement measurement can be performed!!!


  • Seemless connection

    It can be directly connected to our indicators with a cable only.

    Since, no amplifier is required, cable installation can be performed easily.

  • Wide measuring range & high-accuracy

    Stroke: 50mm.

    Resulotion: 2.5µm.

  • High noise immunity.

    RS-422 output type with the enhanced noise immunity.

  • Applcations

    -Force Vs displacement measurement (with our load cells and indicators).

    -Accuracy check of positioning stages.

    -Height measurement after riveting or crimping.

    -Screw height inspection.

Example of use : Press-fitting with force vs. displacement measurement
