The Keyence LK-G35 is a premium laser displacement sensor head from the LK-G Series, developed to provide ultra-precise measurements for short-range applications. With its high resolution, adaptable reflection modes, and selectable sampling speeds, the LK-G35 is a versatile solution for advanced inspection, profiling, and quality control in industries where precision cannot be compromised.

At the core of the LK-G35’s design is its short-range measurement capability, operating at a reference distance of 30 mm in diffuse reflection mode and 23.5 mm in specular reflection mode. This flexibility allows the sensor to adapt to different surface conditions, whether matte, rough, glossy, or reflective, ensuring reliable results across a wide range of target types.

The sensor’s measuring range of ±5 mm (diffuse) and ±4.5 mm (specular) provides excellent coverage for close-up inspections, making it ideal for applications such as thin film thickness measurement, precision component profiling, and microstructure inspection. Its narrow range ensures stable readings with micrometer- and nanometer-level consistency.

One of the LK-G35’s most important strengths is its exceptional accuracy. With a linearity of ±0.05% of full scale and repeatability as fine as 0.05 µm, it delivers highly reliable results for demanding applications. In high-resolution mode, repeatability improves to an extraordinary 0.01 µm, enabling the detection of even the smallest surface variations or dimensional changes. This level of performance makes the sensor indispensable in industries such as semiconductors, electronics, and precision machining.

The LK-G35 also features six selectable sampling frequencies, ranging from 20 µs to 1,000 µs. This allows engineers to adjust the balance between speed and stability depending on the application. At its fastest setting of 20 µs, the sensor can capture rapid changes in target height, making it suitable for real-time monitoring on high-speed production lines. Alternatively, longer sampling intervals enhance stability in environments where slower, highly accurate measurements are required.

Another advantage is the sensor’s dual reflection mode capability, which broadens its usability. In diffuse mode, it provides stable measurement on matte or irregular surfaces, while in specular mode, it excels at handling reflective or polished materials. This adaptability reduces the need for separate sensors, enhancing efficiency in mixed-material environments.

Compact, robust, and easy to integrate, the LK-G35 is designed for continuous operation in demanding industrial conditions. Its reliability and advanced functionality ensure it can withstand production stresses while consistently delivering high-precision results.

In summary, the Keyence LK-G35 Laser Displacement Sensor Head offers nanometer-level accuracy, short-range adaptability, high-speed sampling, and versatile reflection modes. Compact yet powerful, it is an essential solution for engineers and manufacturers seeking superior performance in advanced measurement and inspection systems.
