High-Accuracy 2D Laser Displacement Sensor

LJ-G5000 series


The LJ-G Series accurately measures the surface profile of targets in X and Z directions. The height, width or gap on a surface profile can be measured using 28 measurement modes.

    • Simultaneous measurements can be done at 8 points.
    • E3-CMOS image sensor provides stable measurements
    • The Quatro link system achieves the highest sampling speed in its class, 3.8 ms.
    • High-speed sampling of 3.8 ms, high-accuracy of ±0.1% of F.S.
    • Simple setting menu(First in its class)
    • The LJ-G Series accurately captures surface profiles in 2D at high-speed.Cutting edge technology is built into the LJ-G Series.

    • Used in a wide range of industries. KEYENCE has a 2D Laser Displacement Sensor to meet any application need.

Case Studies

  • By using KEYENCE’s LJ-G sensor, the Automotive Equipment Manufacturer has automated its inspection of airbag deployment slits in vehicle dashboards. This resulted in stable measurements and a fast return on investment.
