Confocal Fiber Displacement Sensor ZW-8000/7000/5000 Series

Incorporating the white light confocal principle of measurement, the ZW-8000/7000/5000 Series is a non-contact-type displacement sensor that can continuously measure the height of objects with various materials and shapes with an accuracy of microns while moving the sensor head.


  • Ideal for measuring rattling or inclined transparent objects or mirror surfaces such as thin film sheets or glass (ZW-8000 series)
  • Accurate shape measurement of workpieces with coarse surfaces while the sensor head is moving, Measurement period : 20 μs (ZW-7000 series)
  • Ultra-compact, ultra-lightweight sensor head (ZW-8000/7000/5000 series)


  • Power supply voltage:21.6 to 26.4 VDC (including ripple)
  • External interface: EtherCAT, EtherNet/IP™, EtherNet, RS-232C, Analog output, Parallel I/O
  • Measurement cycle: 20μs to 80μs
  • Measuring range: 7±0.3mm, 10±0.5mm, 10±0.7mm, 20±1mm, 30±2mm, 40±3mm
  • Static resolution: 0.002μm to 0.024μm
