The Keyence LJ-G080 is a high-precision 2D laser displacement sensor head engineered for advanced surface and profile measurement. Featuring a diffuse reflective design with a reference distance of 80 mm, this model offers an effective balance between measurement range, resolution, and versatility. It is well-suited for applications such as height profiling, dimensional measurement, and inspection of complex surfaces in manufacturing environments.
The LJ-G080 delivers excellent measurement performance across both axes. On the Z-axis (height), it achieves a measuring range of ±23 mm with a resolution of 1 µm and linearity of ±0.1% F.S., making it capable of detecting even subtle dimensional deviations. On the X-axis (width), it provides a field of view from 25 mm to 39 mm depending on the working distance, with a repeatability of 10 µm, ensuring reliable cross-sectional profiling. Its laser spot line, measuring approximately 80 µm × 46 mm at the reference distance, allows the sensor to capture detailed data over a wide area in a single scan.
Equipped with a red semiconductor laser (655 nm, Class 2 safety level), the LJ-G080 ensures both powerful and safe operation. The laser output of 0.95 mW is sufficient for stable detection without compromising operator safety, while compliance with IEC 60825-1 and FDA Class II standards ensures global compatibility. Its fast sampling cycle of 3.8 ms makes it suitable for high-speed processes, while the temperature characteristic of 0.02% F.S./°C guarantees stable performance even under fluctuating factory conditions.
The LJ-G080 is designed with rugged industrial applications in mind. With an IP67 enclosure rating, an aluminum body, and the ability to resist vibration (10–55 Hz, 1.5 mm double amplitude), it offers durability in harsh production environments. It also maintains stable operation under ambient lighting up to 5,000 lux, reducing the risk of interference from surrounding illumination.
Compact and robust at 350 g, the LJ-G080 is easy to integrate into existing inspection systems, whether mounted in-line for real-time process monitoring or used in standalone measurement setups. Its reliability, precision, and adaptability make it an ideal solution for industries such as automotive, electronics, precision machining, and packaging.
In summary, the Keyence LJ-G080 provides a combination of high-accuracy 2D measurement, fast sampling, and durable construction, making it a trusted choice for manufacturers requiring stable and precise quality control in challenging environments.
