The Keyence LJ-G200 Sensor Head is a high-performance laser displacement and profiling sensor designed to provide precision in industrial inspection and measurement applications. As part of the LJ-G series, it utilizes advanced optical technology to deliver highly accurate surface profiling, dimensional analysis, and quality assurance in manufacturing environments. With its non-contact measuring method and diffuse reflective mounting, the LJ-G200 is engineered to meet the demands of industries that require speed, accuracy, and durability.

At the core of the LJ-G200 is its red semiconductor laser operating at 655 nm, which provides visible laser guidance for ease of alignment. The laser is classified as a Class 2 laser product, ensuring compliance with both IEC and FDA safety standards. Its output power of 0.95 mW allows it to project a stable, reliable measurement line without posing excessive risks to operators. The beam shape at the reference distance is approximately 180 µm × 70 mm, offering a fine resolution across a wide field of view for capturing minute surface details.

The measurement capabilities of the LJ-G200 are equally impressive. It delivers a Z-axis measuring range of ±48 mm, allowing it to detect subtle variations in height across target surfaces. The X-axis field of view spans from 51 mm at the near range to 73 mm at the far range, giving it the flexibility to handle targets of varying widths and positions. The reference measuring distance is optimized at 200 mm, making it suitable for medium-range applications where stability and precision are critical.

One of the defining strengths of the LJ-G200 is its diffuse reflective design, which allows for accurate measurement without requiring specialized reflective surfaces. This makes it well-suited for applications involving diverse materials such as metals, plastics, glass, and composites. By eliminating direct contact, the sensor avoids potential damage to sensitive parts and ensures consistent results even when targets are in motion.

In industrial applications, the LJ-G200 finds use in profile measurement, thickness inspection, gap detection, and dimensional accuracy checks. It is commonly employed in fields such as automotive manufacturing, electronics assembly, precision machining, and packaging. Its high speed and ability to deliver reliable results in real-time make it indispensable for automated inspection systems.

Overall, the Keyence LJ-G200 offers a powerful balance of precision, flexibility, and safety. By combining wide measurement ranges, advanced laser technology, and robust design, it supports quality assurance initiatives and helps manufacturers maintain high standards of productivity and accuracy.
