What is the maximum detection distance of DADISICK measuring light curtains?
DADISICK DK-QL measuring light curtains offer two detection distance ranges depending on the beam spacing: 0.3-1 meter for high-precision 2.5mm spacing models, and 0.3-6 meters for standard 10mm and 20mm spacing models.
Detection Distance by Model
| Model Series | Beam Spacing | Detection Distance | Best For |
|---|---|---|---|
| DK-QL32-2.5 | 2.5mm | 0.3 - 1 meter | Close-range precision measurement |
| DK-QL Series (10mm) | 10mm | 0.3 - 6 meters | General industrial measurement |
| DK-QL Series (20mm) | 20mm | 0.3 - 6 meters | Large object detection |
Factors Affecting Detection Distance
Ambient Light
Strong ambient light (direct sunlight, welding arcs) can reduce effective detection distance. DADISICK DK-QL models include optical filtering to mitigate this.
Environmental Conditions
Dust, fog, and humidity can scatter infrared beams, potentially reducing effective range. Regular cleaning of optical surfaces is recommended.
Alignment Quality
Precise alignment between emitter and receiver is critical for achieving maximum detection distance. Even small misalignment reduces effective range.
Case Example: A logistics company uses DADISICK DK-QL200-10-1990 (10mm spacing, 0.3-6M range) to measure package dimensions on a conveyor. The emitter and receiver are mounted 4 meters apart, well within the 6-meter maximum. The system measures packages up to 1990mm height with ±10mm accuracy.
