An eddy-current noncontact displacement sensor. Measures the displacement of the target (electrical conductor) to the sensor with high accuracy. It can measure static displacement to high-speed phenomenon, and can be applicable to measurement of displacement, thickness, eccentricity measurement, etc.

Product Overview

High performance displacement sensor with exceptional stability

Achieving exceptional reliability and stability with our proprietary eddy-current method, VC Series have been favored by many of our customers. Provides important data with high accuracy in diverse applications, including production equipment monitoring, production quality control, research institute, etc.


  • Reliable, superior temperature characteristics
    Provides stable measurement in a severe condition where the temperature wildly changes through time . The sensor probe, the area that is placed in the most severe condition, is carefully designed with finely selected materials and crafted with our stringent quality control system so that the temperature coefficient becomes below ±0.015% of F.S./℃ (typical).
    Also the sensor has a temperature compensation circuit on the demodulation circuit to suppress the temperature coefficient below ±0.05% of F.S./℃.
  • Internal circuits that ensures high stability
    For fine, stable measurement, demodulation accuracy of the bridge circuit inside the sensor is indispensable. VC Series uses a crystal demodulator to stabilize the frequency, and takes the output voltage signals back in to the AGC circuit for amplitude control.
  • Fine resolution linear outputs
    Outputs finely calibrated linear signals proportional to the detected distance . The output signal is 0 to 5 VDC with displacement and vibration contents, making it applicable to a wide range of applications from static displacement measurement to high-speed vibration measurement.
  • A broad range of lineup to meet the needs
    Nine range types from 0 – 500μm to 0 – 25mm are available for different applications. (0 – 500μm is not available for the fine model.) The sensor lineup consists of standard and fine, water resistant (standard) models for various application use.
