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.

Magnetostrictive linear position sensors

Senyd magnetostrictive linear position sensor is a type of sensor used to measure linear position by utilizing the magnetostrictive effect. This sensor consists of a magnetostrictive waveguide, which is a wire or rod made of a magnetostrictive material such as nickel or iron.The sensor works by sending a high-frequency electrical pulse down the magnetostrictive waveguide, which generates a magnetic field. When a movable magnet interacts with this magnetic field, it causes the magnetostrictive material to change its shape slightly, producing a mechanical wave that travels back to the sensor head. By measuring the time it takes for this wave to return to the sensor head, the sensor can accurately determine the position of the magnet along the waveguide.
