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.

Senyd Rotary Encoder

Rotary encoders are required wherever physical quantities such as rotational speed, angle of rotation, velocity or acceleration are to be monitored. In combination with cable pulls, they can also measure linear movements and lengths.

Rotary encoders from Senyd are used in a wide variety of industries—from mechanical and plant engineering to material handling and the renewable energy sector. Whether heavy-duty, offshore or hazardous areas: Senyd offers the right incremental or absolute rotary encoder for all application requirements. 

With Senyd you can reliably record every movement in your application.

Optical vs. Magnetic Scanning

High resolutions can be easily achieved with Senyd optical rotary encoders. A code disk with radial slits is used for this purpose. An LED sends light through the radial slits to a receiver located on the other side of the code disc. The rotation of the disk modulates the light, and the receiver converts it into an electrical signal.

The magnetic rotary encoders from Senyd are particularly robust and therefore ideally suited for use in harsh environments. Due    to energy harvesting, the magnetic absolute rotary encoders do not require an external power supply to save their current position. As a result, they perform reliably even in the event of power failures.
