DL50-N2228 SICK Dx50 Long-Range Distance Sensor Laser

Precision Optical Architecture Overview

The DL50-N2228 sensor engineered by SICK represents a high-performance distance measurement tool within the Dx50 series. Utilizing advanced HDDM optical time-of-flight technology, it delivers dependable millimeter-level precision across demanding industrial automation environments.

Core Technical Parameters & Performance Matrix

Mechanical Integration & Thermal Engineering

Constructed within a heavy-duty zinc die-cast housing (ZNAL4CU1), the DL50-N2228 withstands severe mechanical shocks and vibrations. An integrated internal heating element allows reliable startup and continuous operation in cold-storage and deep-freeze facilities down to -40 degrees Celsius. The enclosure meets IP65 protection standards when secured with an 8-pin M12 male connector.

Advanced Diagnostics & Local Configuration

An onboard LC display combined with intuitive menu navigation buttons facilitates real-time troubleshooting and parameter adjustments directly on-site. The RS-422 interface streams live distance data and internal device status to master controllers, ensuring immediate detection of signal loss or reflector misalignment.

Global Logistics, Fulfillment, and Warranty Terms

• Global orders dispatch within 24 to 48 hours.
• Secure shipping managed through premier carriers: FedEx, UPS, and DHL.
• All units backed by a comprehensive 12-month replacement warranty.

Target Industrial Equipment & Operational Scenarios

The DL50-N2228 excels in high-bay warehouse stacker cranes, automated guided vehicles (AGVs), long-span gantry positioning systems, and cold-storage logistics monitoring networks requiring high-speed distance tracking.

Global PLC Spare HUB Field Engineering Insight

Technicians at Global PLC Spare HUB frequently deploy the DL50-N2228 in sub-zero refrigerated warehouses where standard optics fog or freeze. In a recent automated freezer storage retrofit, the internal heating element maintained optical window clarity at -30 degrees Celsius, eliminating condensation downtime and preserving precise vertical positioning accuracy for stacker cranes.

Strategic Selection Guide & Technical FAQ

Selection Guide:
Choose this sensor when your application demands long-range measurement up to 50 meters with high immunity to ambient light, integrated low-temperature heating, and serial RS-422 data output in harsh industrial settings.

FAQ:

Question:
Why is Diamond Grade reflective tape mandatory for achieving the full 50-meter range?

Answer:
High-grade retro-reflective targets maximize light return efficiency to the optical receiver, compensating for beam dispersion over extended distances.

Question:
What is the purpose of the internal heating element during cold-environment start-ups?

Answer:
It prevents internal frost accumulation and condensation on the PMMA optical window, ensuring safe operation down to -40 degrees Celsius.

Question:
Can the RS-422 interface transmit raw distance values concurrently with the NPN digital output?

Answer:
Yes, the serial interface streams continuous numerical measurements while the NPN output handles discrete switching thresholds.

Question:
How does HDDM technology maintain stability under high ambient light conditions?

Answer:
High Definition Distance Measurement utilizes advanced optical filtering and pulse evaluation algorithms to suppress background sunlight or factory glare.

Question:
What specific power supply considerations apply when operating the internal heater?

Answer:
The supply voltage must exceed 15V DC (typically 18V to 30V DC), and power supplies must accommodate peak loads up to 28W when the heater activates.
