Leuze DRT 25C Dynamic Reference Diffuse Sensor
Sensors must safely detect a wide variety of products and films on the conveyor belts of packaging machines (HFFS, FS, Thermoform, and VFFS) for confectionery and baked goods.
In addition, they must work continuously after a product changeover, without requiring further setup.
The Leuze DRT 25C Dynamic Reference Diffuse Sensor is specialized for this type of application.
It works reliably with flat and spherical products, transparent to high-gloss films as well as irregular shapes and contours.
Its innovative detection mechanism with the unique reference technology and three light spots uses the conveyor as a point of reference, not the product.
This is how the DRT 25C detects any type of object as a ‘deviation’ to the conveyor belt surface.
The detection is independent of the surface characteristics of the products, such as the colour, gloss, and transparency.
Advantages for you include…
- The reliable detection of objects even with difficult shapes and surfaces ensures continuous machine output and prevents downtime.
- No realignment of the sensor is required when switching products or packaging materials. The shorter setup times result in higher product volumes.
- Fast and easy teaching setup of the belt surface using the teach button. Only one universal mounting position is required for all objects.
- Reliable operation even if the conveyor belt is soiled or vibrating.
- IO-Link for easy integration of additional functions in the machine control, such as warning message in case of excessive contamination, use of the counter built into the sensor, or locking of the teach button
its three light beams, the DRT 25C reliably detects the front edges of the objects and ensures that the process goes smoothly without any machine downtime.
Thanks to the wide scan, even products with openings, such as cookie curls, are safely detected as a continuous piece.
Packaging’s with different colours and transparency are safely detected as a ‘deviation’ from the conveyor belt surface due to the reference technology.
This means that even machines that process a wide range of films can be equipped with a single sensor type.
When performing the initial setup, the conveyor belt surface is taught in as a point of reference with the teach button.
After a product changeover, it is not necessary to adjust this setting, as the point of reference remains the same.
In addition, the mounting position, and the alignment of the sensor itself can be continuously used for the widest variety of objects.
This means that no setup effort is required for the sensor when changing products.
The sensor will detect all objects that do not correspond to the conveyor belt surface. Even contamination on the conveyor belt can be considered with this technology.
Technical properties are …
- Reference technology and three LED light spots for reliable object detection with the widest variety of shapes and surfaces.
- Large working range for conveyor belt spacings of 50-200 mm
- High switching frequency of 750 Hz for belt speeds up to 2 m/s
- Easy configuration via an operating button (teach button)
- IO-Link interface for standardized communication with the machine control in the dual channel principle or in SIO mode
- Compact housing: only 15 mm x 42.7 mm x 30 mm for universal use
