What Is the SICK DT50-N2113 Distance Sensor?

The SICK DT50-N2113 is a Class 2 laser distance sensor from the Dx50 DT50 Hi series. It uses HDDM optical time-of-flight measurement to detect natural objects across a 200 mm to 20,000 mm range. With repeatability of ≥ 1 mm and typical accuracy of ± 7 mm, This unit supports precise positioning in demanding oil and gas automation.

Each unit sensor is built for demanding environments. The zinc die-cast housing and IP65 rating protect the optics from dust and water jets. Consequently, the sensor reduces unplanned downtime in mission-critical processes.

Key Specifications and Cost Implications

• Measurement range: 200 mm to 20,000 mm on 90% remission targets. This wide span lets one sensor cover multiple positions, which lowers spare-parts inventory costs.
• Repeatability: ≥ 1 mm supports consistent triggering and reduces false rejects in positioning tasks.
• Accuracy: Typ. ± 7 mm is suitable for presence and level checks where exact sub-millimeter precision is not required.
• Supply voltage: DC 10 V ... 30 V with reverse-polarity protection. The wide input range tolerates common industrial supply variations and avoids extra conditioning hardware.
• Power consumption: ≤ 2.1 W without external load keeps heat generation low inside cabinets and supports energy-efficient panel design.
• Operating temperature: -30 °C ... +65 °C as standard. With two cooling plates the range extends to -30 °C ... +80 °C, and with two cooling plates plus a protection filter it reaches -30 °C ... +140 °C (Uv ≤ 24 V).
• Response time: Fast 15 ms, Medium 30 ms, Slow 80 ms via the averaging setting. Faster response shortens machine cycle times, while slower averaging improves stability in dusty air.
• Outputs: One NPN digital output (≤ 100 mA), one 4 mA ... 20 mA current output (≤ 300 Ω, 16-bit), and a multifunctional input.
• Connection: M12 5-pin male connector simplifies field replacement and reduces wiring time.
• Protection: IP65 enclosure (EN 60529) limits ingress-related failures and extends service intervals.

How Does This unit Reduce Operating Costs?

Every technical choice in This unit has a cost consequence. The HDDM measurement principle maintains stable readings under changing ambient light. As a result, fewer nuisance trips occur, and maintenance teams spend less time on false alarms. The rugged zinc die-cast housing resists vibration and impact common on oil and gas skids. Therefore, replacement frequency drops compared with plastic-housed sensors.

Furthermore, the wide DC 10 V ... 30 V input accepts standard 24 V supplies without additional regulation. This compatibility reduces engineering hours during retrofit projects. The ≤ 2.1 W power draw also lowers continuous energy consumption in large sensor networks. Over a project lifecycle, these savings accumulate across dozens of measurement points.

The selectable response time lets engineers balance speed against noise. High-speed sorting lines can use the 15 ms setting, while slow-moving level applications can use 80 ms averaging for steadier output. This flexibility avoids over-specifying sensors and keeps per-point costs predictable.

Installation and Commissioning Guidance

Mount This unit using its compact 36.1 mm x 62.7 mm x 57.7 mm housing. The approximate 200 g weight allows direct mounting on standard brackets without heavy supports. Connect the M12 5-pin connector to a compatible cable, and verify the supply voltage is within DC 10 V ... 30 V before power-up.

Use the LC display and menu buttons to set the response time and output mode. For analog integration, confirm the load resistance does not exceed 300 Ω on the 4 mA ... 20 mA loop. The multifunctional input can be configured for triggering or other functions per the official SICK documentation. Always follow local electrical codes and the manufacturer's safety manual when installing laser equipment.

Reliability in Oil and Gas Environments

This unit is field-proven in harsh conditions. Its IP65 rating and -30 °C ... +65 °C operating range cover most outdoor and washdown areas. Where higher temperatures occur, SICK offers cooling plates that extend operation to +80 °C or +140 °C. This scalability means one sensor family can serve multiple zones, simplifying spares planning and reducing inventory costs.

Periodic inspection of the PMMA optical window is advisable. Clean the window according to site procedures, and check the M12 connector for moisture ingress. Because the sensor uses a visible red laser, alignment can be verified visually during maintenance rounds. These simple checks help maintain reliability you can depend on.

Frequently Asked Questions

What is the measuring range of the SICK unit?

This unit measures from 200 mm to 20,000 mm on 90% remission targets. On 18% remission targets the range is 200 mm to 10,000 mm, and on 6% targets it is 200 mm to 5,000 mm.
