Available. The Keyence LK-G152 is a high-speed, high-accuracy CCD laser displacement sensor head designed for precise distance measurements on various surfaces. Part of the LK-G3000 series, it offers a measuring range of ±40 mm with a reference distance of 150 mm for diffused reflection and ±39 mm for specular reflection. Utilizing a red semiconductor laser with a wavelength of 655 nm, the LK-G152 ensures accurate measurements with a linearity of ±0.05% of full scale and a repeatability of 0.5 µm. The sensor head features a spot diameter of approximately 120 µm at the reference distance, enabling precise detection of small features. It supports selectable sampling frequencies of 20, 50, 100, 200, 500, and 1,000 µs, accommodating various application requirements. The device is housed in an aluminum die-cast enclosure with an IP67 rating, ensuring durability in industrial environments. Operating within an ambient temperature range of 0 to +50 °C and relative humidity of 35 to 85% RH (non-condensing), the LK-G152 is suitable for diverse industrial applications requiring precise displacement measurements.
