Expert Review

“Precise long-range sensing.” 35m range with 100µm resolution. ±15mm accuracy. Selectable response time from 2.5ms to 96.5ms – adapt to your application. IO-Link enables easy diagnostics and parameterization.

Manager’s Insight

“Versatile and robust.” One sensor covers many tasks – distance, position, fill level. Analog and digital outputs in one device. IP67 rating withstands harsh environments. Compact size saves space. 12-month warranty included.

Typical Applications

• Distance and position measurement
• Fill level monitoring (tanks, silos)
• Crane and hoist positioning
• Automated guided vehicle (AGV) navigation
• Stacker crane positioning

Compatibility & Integration

• IO-Link V1.1 for easy integration with PLCs
• Analog output: 0-10V or 4-20mA (selectable)
• Digital output: Push-pull (PNP/NPN) – flexible wiring
• SOPAS or IO-Link tools for configuration
• Teach-in function for quick setup

Compare with Other Models

• DL35-B15852 – 35m, 100µm, IO-Link, analog+digital
• DL35-B15853 – same but with different output config
• DL35-B156 – 15m range, lower cost
• DT35 – standard distance sensor, no IO-Link

Frequently Asked Questions

• • What is the maximum range without reflective tape?
  • Range depends on target reflectivity. Max 35m only with “diamond grade” reflective tape. For dark objects, range is shorter.

• • Can I use this sensor outdoors in sunlight?
  • Yes. Infrared light and class 1 laser work in sunlight. Avoid direct sunlight on the receiver lens.

• • What is the difference between response time and output time?
  • Response time is the measurement cycle. Output time is the update rate of analog/digital signals. Both are configurable.

• • Does the sensor have IO-Link?
  • Yes. IO-Link V1.1 is built-in. Use it for parameterization, diagnostics, and process data transfer.

• • Can I change the analog output from current to voltage?
  • Yes. Configure output Q2 as 4-20mA or 0-10V via software or teach-in.

• What is the warm-up time?
• Up to 20 minutes for full accuracy. During warm-up, accuracy may be slightly reduced.

Selection Guide

• Choose DL35-B15852 if: you need 35m range with 100µm resolution and IO-Link.
• For shorter range (15m): consider DL35-B156 (lower cost).
• If you don’t need IO-Link: DT35 series offers basic analog/digital outputs.
• Check your supply voltage: 12-30V DC – ensure clean power.
• Mounting: Compact size fits tight spaces. Use M12 connector for quick wiring.
