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.

Laser distance sensor

Senyd TOF principle laser distance sensors operate on the principle of measuring the time it takes for a laser pulse to travel from the sensor to the target object and back. Here's how TOF laser distance sensors work:

  1. Emitting laser pulse: The sensor emits a laser pulse towards the target object.

  2. Reflection: The laser pulse hits the target object and reflects back towards the sensor.

  3. Time measurement: The sensor measures the time it takes for the laser pulse to travel to the object and back. This time measurement is directly proportional to the distance between the sensor and the object.

  4. Distance calculation: Using the speed of light as a constant, the sensor calculates the distance to the object based on the time it took for the laser pulse to travel back and forth.
