Ultra-High Speed In-line Profilometer

LJ-V series

  • CE Marking

1. Blue Laser Optical System

The use of a blue laser enables ultra-stable and highly accurate measurements. Able to measure on black surfaces or inclines with low reflectance as well as highly reflective metallic surfaces. A very accurate profile is captured even when the target has a mixture of various colors and material finishes.

2. Revolutionary Speed and Stability

World's fastest sampling speed among all 2D laser measuring instruments . This makes it possible to measure the various shapes of produts on a moving conveyor or through an equipment at high speeds without missing an item. High-speed sampling is also effective in reducing variations in measurement results.

3. An emphasis on inline measurement

A position adjustment function is built-in to correct positional misalignment of the targets which removes measurement errors. A high-flex cable for robotic installs and movable fixtures is also included within the lineup. A great deal of time and effort has gone into designing the functions and specifications for incline measurement.

Case Studies

  • Displacement Sensors
    Duhamel DTI has designed a bench for testing the magnetic circuits of electrical contactors that uses the LJ-G Series 2D laser displacement sensor by KEYENCE. The resulting performance is extraordinary - a rate of 4,000 to 5,000 parts per hour with micron level accuracy.

  • Measurement Sensors
    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.
