The SICK DT50-P1113 is a Sensor for industrial control and automation applications.

SICK DT50-P1113 is a Class 2 laser distance sensor from the Dx50 series that measures natural objects from 200 mm to 10,000 mm without a reflector. It combines HDDM™ optical time-of-flight measurement with a zinc die-cast housing rated IP65 for demanding industrial environments.

What makes the DT50-P1113 suitable for oil and gas applications?

This unit is built for demanding environments where dust, moisture, and temperature swings are routine. Its zinc die-cast housing (ZNAL4CU1) with an acrylic glass (PMMA) optical window protects the optics while the IP65 rating (EN 60529) guards against water jets and dust ingress. The sensor operates from -30 °C to +65 °C as standard, and SICK offers cooling plates that extend the upper limit to +80 °C or +140 °C when required. This flexibility allows the same sensor model to serve in both sheltered skids and hotter process areas.

How does This unit perform in critical oil and gas measurement tasks?

Oil and gas operations often require reliable level or position feedback where contact-based sensors may fail. This unit uses direct diffuse distance measurement up to 10 m on natural objects, so no reflector is needed. This reduces installation complexity and potential failure points. The HDDM™ technology provides high repeatability and ambient light stability, which helps maintain accuracy in outdoor or brightly lit areas. The analog 4 mA ... 20 mA output integrates with standard control systems, while the PNP digital output can trigger alarms or counters. For mission-critical processes, the sensor's reverse-polarity protection and short-circuit network capability (max. 8 A) add a layer of electrical robustness.

Integration and installation guidance

This unit connects via a 5-pin M12 male connector, a common interface in industrial automation. The supply voltage range of DC 10 V ... 30 V accommodates typical 24 V control cabinets. When wiring the analog output, ensure the load does not exceed 300 Ω to maintain accuracy. The sensor's compact dimensions and 200 g weight simplify mounting on brackets or machine frames. For high-temperature zones, SICK offers cooling plates and protection filters that extend the operating range; these accessories should be specified separately based on the application's ambient conditions. Always follow the manufacturer's installation instructions for optimal performance.

Reliability and maintenance in harsh environments

Field-proven reliability starts with the housing: zinc die-cast resists mechanical impact and corrosion better than plastic. The PMMA optical window is durable but should be inspected periodically for dust or buildup that could affect measurement. In oil and gas plants, cleaning the window with a soft cloth and appropriate lens cleaner is recommended as part of routine maintenance. The sensor's IP65 rating means it can withstand washdowns, but high-pressure steam should be avoided. The wide storage temperature range of -40 °C ... +75 °C allows for safe transport and storage in unheated warehouses. Because This unit has no moving parts, wear is minimal, contributing to long service life and reduced downtime.

Frequently asked questions

What is the measurement range of the SICK unit?

The SICK unit measures from 200 mm to 10,000 mm on targets with 90% remission. On darker surfaces (6% remission), the range is 200 mm to 4,000 mm.

Can This unit operate in high-temperature areas?

The standard operating temperature is -30 °C to +65 °C. With two cooling plates, the upper limit extends to +80 °C, and with two cooling plates plus a protection filter, up to +140 °C (Uv ≤ 24 V).

What type of output does This unit provide?

The SICK unit offers one PNP digital output (≤ 100 mA) and one analog current output (4 mA ... 20 mA, ≤ 300 Ω, 16-bit).

Is This unit protected against reverse polarity?

Yes, the supply voltage input is reverse-polarity protected. The sensor operates on DC 10 V ... 30 V and can handle a maximum short-circuit current of 8 A in a short-circuit network.

What is the laser class of This unit?

The SICK unit uses a Class 2 laser according to IEC 60825-1:2014 and EN 60825-1:2014, with a wavelength of 658 nm and average optical power below 1 mW.
