DR35-B15522 SICK Dx35 Series Retro-Reflective Laser Distance Sensor

Global PLC Spare HUB's Insight

Automated high-speed sorting and long-range positioning applications often struggle with erratic distance tracking when confronted with varying surface reflectivities or low ambient light conditions. Drawing from our hands-on automation sensing deployment experience, the SICK DR35-B15522 optical distance sensor from the Dx35 Series harnesses advanced HDDM (High Definition Distance Measurement) time-of-flight technology to deliver precise position monitoring up to 35 meters on reflective tape. Equipped with dual push-pull outputs and an IO-Link V1.1 interface, it bridges rugged industrial reliability with high-speed response down to 2.5 ms.

Frequently Asked Questions

Question: How does the HDDM time-of-flight technology improve performance over standard photoelectric sensors?

Answer: HDDM technology measures the exact time light takes to travel to the target and back, providing exceptional immunity to ambient light and highly accurate distance values independent of object color.

Question: What is the purpose of the multifunctional input (MF) on this sensor model?

Answer: The multifunctional input allows external control functions such as laser-off control, external teach-in programming, or trigger inputs depending on user configuration.

Question: Can the switching hysteresis be adjusted for applications with vibrating targets?

Answer: Yes, the switching hysteresis can be customized between 0 mm and 34,950 mm via IO-Link to prevent output chattering caused by target vibration.

Question: Why does the supply voltage requirement change when IO-Link communication is enabled?

Answer: When IO-Link is active, the supply voltage (Vs) must exceed 18V to ensure stable bidirectional digital communication and internal logic operations.

Question: What precautions should be taken when mounting the sensor near high-temperature equipment?

Answer: Ensure the ambient operating temperature does not exceed +55 °C when operating at supply voltages up to 24V, and provide thermal shielding if radiant heat is present.

Expert Buying Guide

• Verify that your target surface uses high-grade reflective tape (such as Diamond Grade) to achieve the full 35-meter sensing range capability.
• Confirm your control architecture supports IO-Link V1.1 if you intend to utilize advanced parameter cloning and real-time diagnostic feedback.
• Evaluate your PLC input card compatibility to ensure seamless integration with the dual push-pull (PNP/NPN) switching outputs.
