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.

Liquid Level switch

This level switch is also called Float sensor, liquid level sensor, reed switch etc.

They are used wherever it is necessary to control and regulate the level of liquids (e.g. water, oil, etc.). The sensor has a float equipped with a magnet, which moves vertically along the guide tube under the influence of the buoyancy force of the liquid, causing the reed switch located in the tube to short circuit or open. They are usually mounted in the bottom or lid of the tank, so they can be used to control the lower or upper level of the liquid. They are made of stainless steel and can be used in a wide range of temperatures.
