Instead of using print marks or place markers, SICK’s ML20 Markless sensor is based on pattern recognition technology. This means that web film control in bottling and labeling machines can take advantage of the sensing speeds up to 7 m/s and an accuracy of up to 0.6 mm capabilities of the sensor.
In addition to improving process transitions when multiple film changes are required by OEMs and end users, the sensor has an IP 65 rating for a high degree of operating environment protection. The sensor is programmed through SOPAS software, the sensor on-board control panel or a “teach-in” process.
