'Sensor solutions for packaging industry from Leuze electronic'



In developing our sensors, we therefore concentrate on the needs of selected focus industries – such as the filling and packaging of beverages. This is one reason why we have developed special solutions for the detection of transparent bottles or labels, e.g., with our PRK 18B and GSU 14C. The MLD 300 and 500 multiple light beam safety devices also demonstrate how efficient professional safety at work can be today in the beverage industry.



  • Unique successor model of our PRK 18 in chemically nickel-plated metal housing;
  • The calibrated aBEAM optics precisely strike even small reflectors without time-consuming alignment;
  • Precise repeatability thanks to a jitter time of just 32 μs;
  • Tracking function considerably reduces the amount of work required for cleaning and readjustment.



  • Precise detection of labels in robust metal housing;
  • Ultrasonic forked sensor for reliable detection and universal application;
  • ALC – Automatic Level Control pervents stops resulting from soiling or changes in the material;
  • Special functions for transparent labels on transparent carrier.

  • Integrated muting functions can be configured wiring connections;
  • Laser alignment aid for easy alignment over long distances;
  • All settings and configuration of the muting modes without PC;
  • Direct connection to AS-i bus without additional coupling module.
