Non-contact high-precision detection sensor utilizing laser light. Used in industrial robots and automation equipment for workpiece positioning, dimensional measurement, distance measurement, and displacement measurement. Capable of high-precision measurement in micrometer units through triangulation and TOF methods, ideal for quality control in metal processing, assembly lines, and inspection equipment. Available in types including laser displacement sensors, laser distance sensors, and laser area sensors, compatible with detection of transparent objects and glossy surfaces. Unlike conventional photoelectric sensors and proximity sensors, this is a specialized sensor category focused on high-precision non-contact measurement using laser light.
