A New Level Of Precision [Laser Displacement /Sensor BD Series]

BD SeriesLaser Displacement Sensors (Sensor Head and Amplifier Unit)

The BD series laser displacement sensors can measure thickness, width, level difference, disparity, curve, evenness of target objects by detecting the amount of displacement. The sensors offer accurate and stable measurement with minimal influence from target color or material. The sensor head and amplifier unit are detachable for easier maintenance and up to 8 sensor amplifier units can be interconnected with mutual interference prevention function.

Accurate Displacement Measurement on Various Materials

The sensors can accurately detect various target material or color including black/white paper, stainless steel, rubber, PCB, etc.


Easy Configuration with Movement Average, Differential, and Median Filters

Movement average, differential, and median filters allow for accurate and stable correction in measurement values in the event of sudden changes from mechanical noise or other variables.

  • Median filter

    removes any sudden value changes.

  • Movement average filter

    averages the measured values to reduce the overall changes to the measurement values.

  • Differential filter

    transmits the differential value between current and previous measured values. Used to measure sudden changes in value.

  • Various Calculation Functions

    Supports various calculation functions (OFF, ADD-AB, SUB-AB, AVG)
    - OFF: independent measurement (calculation function not used)
    - ADD-AB: Adds the measured values from sensor heads A/B (used to measure thickness)
    - SUB-AB: Subtracts the measured values from sensor heads A/B (used to measure level difference/ disparity)
    - AVG: averages the measured values from all connected sensor heads (used to measure evenness)
    - Cannot use more than 2 calculation functions with interconnected sensor amplifier units

Capable of Measuring up to 1 m

The BD-600 model is capable of measuring up to 1 m suitable for in harsh environment including high temperatures, and also features easy measurement of width and step of thick steel plates.

  • Maximum Resolution of 1 ㎛

    Laser displacement sensors feature a maximum resolution of 1 ㎛ (BD-030) for stable and precise measurements.
    The BD-300 model features resolution of 20 ㎛

  • Interconnection of Sensor Amplifier Units and Mutual Interference Prevention

    Up to 8 sensor amplifier units can be interconnected. The channels for the amplifier units are automatically sorted when connected together. (Each sensor amplifier unit requires independent power supply)

Dedicated Software ‘atDisplacement’

Dedicated software ‘atDisplacement’ offers user-friendly interface with live data, life graphs and wave graphs for easy monitoring of various measurement values in real-time. Set values can be immediately checked during the setting.

  • Channel Graph

    Real-time monitoring of set value (SV).

  • Live Data

    Displays the status of amplifier unit and measured value to number. The data is automatically scaled for ease of use in future analysis.

  • Live Graph

    Displays the graph color of amplifier unit per channel and present value (PV).

  • Wave Graph

    Displays received light waveform per unit in real time. Up to 8 sensor units can be monitored.

  • Robot Type Extension Cables for Moving Applications (Sold Separately)

    1 m, 2 m, 5 m, 10 m cables are available for application in diverse environments without breaking.
