Professional Application FAQ

• What is the maximum reliable detection range for dark objects?

For dark objects with 6% remission factor, the sensor reliably measures distances from 50 mm to 3,100 mm in typical industrial conditions.

• How do I configure the output for my specific control system?

Use the teach-in function to easily set analog ranges or digital thresholds. The output Q2 can be adapted as 4-20 mA, 0-10 V, or as a digital switch output.

• Can this sensor operate in outdoor environments?

With its IP67 rating and wide temperature range, the DT35-B15551S04 can handle challenging environments, though it's primarily designed for indoor industrial applications.

• What advantage does IO-Link provide for this sensor?

IO-Link enables advanced parameterization, real-time diagnostics, data storage, and simplified integration with modern automation systems for smart factory applications.

• How should I select the appropriate response time setting?

Choose faster response (4.5-12.5 ms) for high-speed applications. Use slower settings (48.5-192.5 ms) in environments with interference to ensure stable, accurate measurements.
