In the case of high-performance labelers with large roll diameter, the rotational speed of the label roll is controlled. The US US 12 M 400 JU-B4 measures the outer diameter of the label material; the determined measured value allows for the rotational speed of the roller to be adjusted continuously in the process.

In a label printing machine, the passage control of the label strip is performed with a dancer roll. The LAT-45 detects the distance and thus enables the ideal strip tension.

In the cartoning machine, several blisters and the packing insert are introduced into the carton. Before the carton is filled, it must be ensured that the correct number of blisters were provided. The LAT-52 measures the height of the blister stack and thereby controls the number of the blisters shortly before the fusion process.

In a cup-filling machine, liquid products (e.g. yogurt) are filled in containers and sealed with a printed cover film. After sealing, a LAT-52 high-resolution laser distance sensor checks the sealing film at a high measuring rate for size accuracy in order to detect faulty sealing.

Distance sensors act in robots as sensory organs. In order to avoid damage, an ultrasonic sensor checks whether an object is located in the gripper before the gripper closes. The US 08 M 100 G3-T4 is especially suited for this with its small design as well as its ability to detect transparent objects in particular.

Robot-controlled adhesion is becoming increasingly important. In order to ensure high quality and shelf life, the distance of the adhesive nozzle from the object during application of the adhesive must always be optimal. Distance detection in the sub-mm range is performed with an optical distance sensor. Due to its compact design, the LAT-52 can be mounted close to the adhesive nozzle.

Two LAT-52 distance sensors are installed in a suction gripper in order to detect the distance to the top sheet metal part. With the detected distances of the sensors, the location of the gripper in relation to the plate and the approaching speed of the robot is controlled and the timing of the gripping process is thus optimized.

In a robotic cell for final assembly of an engine block, the presence of four spark plug connectors needs to be checked. The LAT-45 has a small laser spot and a high functional reserve. Dark plugs at a far distance can thereby be reliably detected even in a tilted position.

To avoid possible contamination, the colored screw tops in tube handling must always be present. The LVHT-52 satisfies the high requirements of detection security and checks the presence of the colored caps. Switching output and hysteresis can be reliably adjusted via IO-Link in a grid of 0.1  mm.

The precise transfer of samples in small dosing quantities is performed with a pipetting robot. In this process, the associated laboratory vessels for pipetting become smaller and smaller. There are high requirements for positioning of the pipette tips. The positioning of the target vessel is performed with the LAT-52 laser distance sensor.

In agricultural machine technology, sprayers are used for sustainable food security. The booms are guided at a preset height by monitoring the field contours using US 30 M 3000 IU-B4 ultrasonic sensors, so that the needed settings of the boom can be made.

A lifting system must be positioned with respect to height. For this, a LAT-45 distance sensor is used. The LAT-45 is ideally suited for this use due to the robust metallic housing, the high functional safety and a temperature range for operation of up to + 60°C.

Packaging films are produced through film extrusion. In order to keep the diameter constant in blown film extrusion or perform the desired diameter changes, a regulating unit is installed. The diameter of the blown film is measured here with three US 12 M 400 G3-B4 offset ultrasonic sensors with IO-Link. The regulator controls the air supply and thus the diameter of the blown film.

The LAT-45 optical distance sensor detects fill levels of granulate. When the target fill level falls below a certain value, the switching output switches and material is added, and an analog output or IO-Link enables a continuous monitoring of the fill level. An operating temperature of up to + 60°C enables continuous use in the proximity of hot injection molding machines.

During the mechanical processing of the spray can, it must be checked at the processing sites whether the spray can is located in the correct position. An LVHT-52 sensor checks the distance of the spray can from the floor. The switching output of the sensor works with a window function which can be configured or learned in a 0.1 mm grid via IO-Link.

The high-precision distance measurement of the LAT-61 enables the detection of weld seams. With its high measuring frequency of 5000 Hz, the LAT-61 is suited for the measurement of moving objects. The small laser spot enables the precise detection of the positions of small objects.
