Frequently Asked Questions

• What is the maximum range of this sensor?
• 70 m on 90% reflective surfaces, 30 m on 6% reflective surfaces.
• What is the accuracy of the DT500‑A511?
• ±3 mm measurement accuracy with 1 mm repeatability.
• Can I use this sensor outdoors?
• Yes, it is IP65 rated. But avoid direct sunlight above 3,000 lx.
• What output signal does it provide?
• Analog 0‑20 mA, configurable to 4‑20 mA (max load depends on supply voltage).
• Does it work on dark objects?
• Yes, down to 6% reflectivity (30 m range).
