The SICK DT50-N1124 is a Sensor for industrial control and automation applications.

How Do You Measure Distance Reliably in Freezing, Dusty Oil and Gas Environments?

The SICK DT50-N1124 answers that challenge directly: it is a heated optical time-of-flight distance sensor from the Dx50 DT50 Heated family, with a measuring range of 200 mm to 10,000 mm on 90% remission targets. Built for demanding environments, this sensor combines HDDM™ measurement technology with a factory-integrated heater and a rugged zinc die-cast housing.

What Makes the DT50-N1124 Sensor Suited to Mission-Critical Operations?

Oil and gas sites expose sensors to temperature swings, moisture, and vibration. This unit is engineered to keep measuring where standard sensors falter. Its internal heating element allows operation down to -40 °C, while the IP65 enclosure rating protects against dust and water jets. The visible red laser is Class 1 eye-safe per IEC 60825-1:2014, so it can be used in accessible areas without additional laser safety measures.

HDDM™ optical time-of-flight technology delivers high repeatability and ambient light stability. The sensor measures natural objects directly up to 10 m without a reflector, simplifying installation on tanks, conveyors, and pipe racks.

Where Does This Heated Distance Sensor Prove Its Value?

In oil and gas operations, This unit supports level monitoring in storage tanks, position feedback on valves and dampers, and presence detection on conveyors. The integrated heater keeps the optical window clear in cold-storage and deep-freeze areas, reducing downtime caused by frost or condensation. Because the sensor measures directly on natural surfaces, it avoids the maintenance burden of reflectors that can become coated with grime. For outdoor installations, the wide operating temperature range with cooling plates extends usability into hotter process zones.

How Should You Integrate and Maintain This unit?

The M12 8-pin connector simplifies wiring to control systems. The multifunctional input allows switching between measurement modes or triggering a reset, while the analog voltage output provides a continuous distance signal for PLCs or displays. The LC display and menu buttons enable on-site parameter changes without a PC.

For dependable performance, inspect the optical window periodically and clean it according to site procedures. Verify that the supply voltage stays within 18 V ... 30 V, and ensure VS exceeds 15 V when the heater is needed. The zinc die-cast housing resists mechanical impact, but mounting should avoid direct washdown spray beyond IP65 limits.
