Product Description

The Keyence LJ-V7080 is a high-precision 2D/3D laser profiler designed for advanced inline measurement applications. Utilizing a blue semiconductor laser with a wavelength of 405 nm, it offers a measurement range of ±23 mm in the Z-axis (height) and 25 mm in the X-axis (width) at a reference distance of 80 mm. The sensor provides exceptional repeatability of 0.5 µm in the Z-axis and 10 µm in the X-axis, with a linearity of ±0.1% of full scale. It features a high-speed sampling cycle of 16 µs in high-speed mode and 32 µs in advanced function mode, enabling rapid and accurate profiling. The LJ-V7080 is housed in an IP67-rated aluminum enclosure, ensuring durability in industrial environments. With a weight of approximately 400 g, it is suitable for various applications requiring precise surface profiling and dimensional measurement.
