The Keyence LJ-V7080 is a high-performance laser profile sensor head designed for advanced 2D and 3D measurement applications. Operating under diffuse reflection mounting conditions, it uses a blue semiconductor laser (405 nm) to achieve superior accuracy and stability when measuring a wide range of materials, including metals, plastics, and glass. Its ability to generate precise height and width data makes it an indispensable tool for inline inspection and quality assurance.

The LJ-V7080 offers a reference distance of 80 mm with a Z-axis measuring range of ±23 mm (46 mm full scale). It provides exceptional accuracy, with Z-axis repeatability of 0.5 µm and X-axis repeatability of 10 µm, while maintaining linearity within ±0.1% of full scale. The wide X-axis range—25 mm (near side) to 39 mm (far side)—ensures coverage across diverse inspection targets, while the fine profile data interval of 50 µm captures detailed profiles for precise evaluations.

Performance is further enhanced by the sensor’s ultra-fast sampling cycle, achieving speeds of 16 µs in high-speed mode and 32 µs in advanced function mode. This allows for real-time measurements in high-throughput production environments, where both speed and accuracy are critical. The small laser spot size (48 mm × 48 µm at reference distance) ensures that even fine surface variations can be accurately detected.

Durability is another defining feature of the LJ-V7080. Built with an aluminum housing and rated to IP67 standards, it provides protection against dust, water, and harsh operating conditions. It is resistant to ambient light interference up to 10,000 lux, making it suitable for use in brightly lit environments. Additionally, the unit withstands vibration (10–57 Hz, 1.5 mm double amplitude) and shock up to 15 G/6 ms, ensuring stability and long-term reliability in demanding factory settings.

Weighing approximately 400 g, the LJ-V7080 is robust yet manageable for integration into existing automation systems. With temperature characteristics of just 0.01% of F.S./°C, it maintains high stability across varying environmental conditions, ensuring consistent accuracy during long-term operation.

In summary, the Keyence LJ-V7080 Sensor Head is a cutting-edge laser profiler offering unmatched precision, speed, and durability. With its advanced blue laser technology, ultra-fast sampling, and rugged construction, it is an ideal solution for applications requiring high-resolution 3D measurements, such as electronic component inspection, precision machining, and quality assurance in high-speed production lines.
