Mark sensor
Mark sensors are devices used in industrial applications to detect the presence or absence of a mark on a surface. These marks can be in the form of labels, codes, or other indicators that help with positioning, alignment, and quality control in manufacturing processes. Mark sensors use various technologies such as optical, ultrasonic, capacitive, or magnetic to detect the marks accurately and quickly.
Applications
▶Labeling and packaging: Mark sensors are used to detect labels on products or packaging materials to ensure proper labeling and packaging alignment.
▶Printing and coding: Mark sensors are used in printing and coding machines to detect printed marks on products for accurate printing and coding.
▶Assembly line: Mark sensors are used in assembly lines to detect marks on components for proper assembly and alignment.
▶Quality control: Mark sensors are used in quality control processes to detect defects or missing marks on products.
