When Long-Range Detection Meets Demanding Environments

In oil and gas operations, engineers often face a specific challenge: detecting objects reliably across long distances in dusty, vibrating, or outdoor areas where standard photoelectric sensors fail. The SICK DR35-B15822, part of the Dx35 series, solves this by combining HDDM™ optical time-of-flight measurement with a 200 mm to 35,000 mm range on Diamond Grade reflective tape. This retro-reflective switching sensor delivers dependable performance in mission-critical settings.

Built for demanding environments, the DR35-B15822 is a rugged, field-proven solution for industrial automation. Its infrared laser diode (827 nm) is Class 1 eye-safe per IEC 60825-1:2014, ensuring safe operation around personnel. The sensor's core strength lies in its ability to maintain accuracy over extreme distances while offering flexible configuration through IO-Link V1.1 and dual digital outputs.

Key Features and Technical Specifications

This unit integrates several technical parameters that directly impact reliability and integration in oil and gas applications. Below are the critical specifications:

• Measurement Principle: HDDM™ (High Definition Distance Measurement) optical time-of-flight for precise distance readings.
• Measuring Range: 200 mm to 35,000 mm on Diamond Grade reflective tape, suitable for long-range detection.
• Supply Voltage: DC 12 V to 30 V, reverse-polarity protected; IO-Link requires Vs > 18 V.
• Power Consumption: ≤ 1.7 W at +20 °C without load, speed setting Slow.
• Outputs: 2x push-pull (PNP/NPN, Q1 and Q2) with IO-Link V1.1 on Q1; multifunctional input (MF).
• Response Time: Selectable from 2.5 ms (Super Fast) to 96.5 ms (Super Slow).
• Repeatability: ≥ 0.5 mm to 5 mm, depending on speed setting and remission factor.
• Ambient Temperature, Operation: -30 °C to +55 °C (Uv ≤ 24 V).
• Enclosure Protection Rating: IP65 (EN 60529) for protection against dust and water jets.
• Electrical Connection: Male connector M12, 5-pin for secure wiring.

Each parameter is engineered to support reliable operation in harsh conditions. For instance, the wide voltage range accommodates common industrial power supplies, while the IP65 rating ensures resilience in washdown or dusty areas.

Applications and Use Cases in Oil and Gas

This unit excels in scenarios where long-distance, non-contact detection is essential. In tank farms, it can monitor the position of floating roof drains or detect presence of vehicles at loading bays. On drilling rigs, the sensor's 35 m range allows reliable detection of pipe movement along conveyor systems, even in outdoor conditions. Because the sensor uses a Class 1 laser, it is safe for use in areas with frequent personnel access. Additionally, the IO-Link interface enables seamless integration into modern control systems for real-time diagnostics and parameter changes. For mission-critical operations, this sensor provides the reliability you can depend on.

Installation and Setup Guidance

Proper installation is key to maximizing sensor performance. Mount This unit using the M12 5-pin connector for electrical connection, ensuring the supply voltage remains within the 12 V to 30 V DC range. When using IO-Link, verify that the supply voltage exceeds 18 V. The sensor's optical alignment aid simplifies precise targeting of the reflective tape, reducing setup time. For optimal performance, avoid mounting near strong ambient light sources and ensure a clear line of sight to the reflector. The compact dimensions (32 mm x 58.6 mm x 42.7 mm) and lightweight design (approx. 65 g) allow flexible mounting in tight spaces.

Maintenance and Reliability

Regular inspection of the optical window is recommended to maintain measurement accuracy. The acrylic glass (PMMA) window should be cleaned with a soft, lint-free cloth and mild detergent to prevent dust buildup. Because the sensor operates in ambient temperatures from -30 °C to +55 °C, it is suitable for both cold storage areas and hot process zones. The IP65 rating protects against water jets, but prolonged submersion should be avoided. With no moving parts, This unit offers long-term reliability, reducing downtime and maintenance costs in demanding environments.
