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.

Draw-wire Encoder

Draw Wire Sensors are a versatile position measurement device that converts mechanical motion into an electrical signal that may be metered, recorded, or transmitted.

Senyd draw wire sensors consist of a stainless steel displacement cable wound on a threaded drum that is directly coupled to a precision, long-life sensor. Operationally, the sensor is mounted in a fixed position and the extension cable, "draw wire," is attached to a moving object. As movement occurs, the draw wire extracts then later retracts under the power of an internal, engineered spring which also maintains tension on the draw wire throughout its stroke. The rotation of the sensor produces an electrical output proportional to the draw wire's movement giving indication of positional translation.
