The Keyence LK-G150 is a high-performance laser displacement sensor head from the LK-G5000 Series, designed to deliver unparalleled precision and stability in dimensional and profile measurement applications. With its dual reflection capability, ultra-fine spot size, and outstanding accuracy, the LK-G150 is a versatile tool for industries that demand micrometer-level measurement consistency.

One of the defining features of the LK-G150 is its dual reflection capability, which supports both diffuse reflection at 150 mm reference distance and specular reflection at 147.5 mm reference distance. This flexibility allows the sensor to be configured according to the characteristics of the target material, whether it is matte, reflective, or polished. By adapting to different surfaces, the LK-G150 ensures optimal performance across a wide variety of industrial applications.

The sensor also boasts a wide measuring range, offering ±40 mm in diffuse reflection mode and ±39 mm in specular reflection mode. This broad range provides engineers with the ability to measure larger displacements and accommodate thicker or irregular targets, making it ideal for applications such as thickness monitoring, warpage detection, and profile inspection.

Accuracy is where the LK-G150 excels. With linearity of ±0.05% of full scale and repeatability of 0.5 µm, the sensor delivers extremely reliable results even in demanding applications. These specifications make it suitable for tasks requiring ultra-high precision, such as semiconductor wafer inspection, electronics assembly, and high-accuracy machining. The ability to capture fine variations with such consistency helps manufacturers maintain quality standards and reduce process variability.

Another strength of the LK-G150 is its ultra-fine spot diameter of approximately 120 µm. This small beam size allows the sensor to detect minute surface variations and measure small features that would otherwise be overlooked by larger-spot sensors. For industries where fine detail is critical, such as medical device manufacturing or microelectronics, the LK-G150 provides unmatched capability.

Constructed for durability, the LK-G150 is engineered to perform reliably in industrial environments where continuous operation is required. Its robust design ensures long service life while maintaining high accuracy, making it a trusted component of modern quality control and inspection systems.

Applications for the LK-G150 span industries such as automotive, aerospace, electronics, semiconductor, and precision engineering. It is especially valuable for inspection tasks that demand high-resolution profiling, surface analysis, or dimensional verification.

In summary, the Keyence LK-G150 Laser Displacement Sensor Head offers a unique balance of dual reflection modes, wide measurement range, ultra-fine spot size, and outstanding accuracy. Compact, precise, and versatile, it is an indispensable tool for engineers seeking to achieve superior measurement results in advanced automation and inspection environments.
