Detecting Dark or Glossy Items on Conveyor Belts
The sensor can identify objects with very low reflectivity or high gloss without being fooled by background surfaces. This ensures stable detection for products like dark packaging or reflective films in high-speed conveyor systems.
Sorting Multi-Color Caps on Beverage Lines
Cap detection is consistent regardless of color, allowing automated systems to sort items such as bottle caps in various shades without recalibration or sensitivity issues.
Counting Piled Small Parts
The sensor can detect small items in bulk, such as fasteners or clips, even when their colors vary. This makes it suitable for bin-picking, counting, and small-parts inventory control.
Monitoring Cardboard Feed in Packaging Machines
In automated carton feeders, the sensor detects each cardboard sheet reliably, even when the surface is glossy or uneven, preventing missed feeds and improving packaging accuracy.
Ignoring Background in Rotary Packaging Systems
Adjustable detection ranges ensure that moving background structures, such as rotating machinery frames, are ignored, focusing only on the intended target objects.
Alignment in High-Speed Assembly Lines
The concentrated light spot enables precise positioning and part alignment in assembly lines, allowing accurate placement of components at high production speeds.
Reliable Detection in Dusty or Changing Light Environments
The detection principle is based on distance rather than light intensity, so performance remains consistent despite dust, ambient light shifts, or surface color changes.
Compact Installations Requiring High Precision
The small housing size makes it ideal for use in machines with tight installation spaces, while still providing high-precision detection for intricate mechanical layouts.
