SICK DL50-P2228 Dx50 Retro-reflective Sensor
Product Introduction
The SICK DL50-P2228 is a long-range retro-reflective sensor from the Dx50 series. It uses HDDM optical time-of-flight measurement for high-precision distance readings. Moreover, this model targets heavy-duty industrial automation. Its rugged metal housing and integrated heater set it apart from standard sensors.
Technical Specifications
The DL50-P2228 measures from 200 mm to 50,000 mm on diamond grade reflective tape. This 50 m range supports large cranes and storage systems. Furthermore, the light source is a visible red laser diode at 658 nm. The laser is Class 1 and eye-safe per IEC 60825-1:2014 and EN 60825-1:2014. Pulse peak power is 120 mW, with a pulse duration of 2.5 ns.
Response time depends on the averaging setting. Values include 15 ms, 30 ms, and 80 ms. Repeatability is ≥ 1 mm, and measurement accuracy is ± 3 mm. A high-resolution LC display and menu buttons simplify setup.
Outputs and Interfaces
The DL50-P2228 provides one digital PNP output rated at ≤ 100 mA. Additionally, it offers an RS-422 serial communication interface. A multifunctional input supports extra control functions.
Supply voltage is DC 24 V, with an operating window of 18 V to 30 V. However, the internal heating element needs Vs above 15 V. Power consumption reaches ≤ 28 W when the heater runs without external load. The electrical connection uses an M12, 8-pin male connector.
Mechanical and Environmental Parameters
The housing measures 36.1 mm x 62.7 mm x 57.7 mm. It uses zinc die-cast ZNAL4CU1 with an acrylic glass PMMA window. The device weighs about 200 g. The enclosure rating is IP65 per EN 60529.
Operating temperature ranges from –40 °C to +65 °C with the integrated heater. With two cooling plates, the range extends to –40 °C to +80 °C. With two cooling plates and a protection filter, it reaches –40 °C to +140 °C. Storage temperature ranges from –40 °C to +75 °C.
Installation Guide
First, mount the DL50-P2228 on a stable bracket facing the reflective tape. Next, connect the M12, 8-pin connector to a 24 V DC supply. Then, align the sensor using the visible red laser spot. The LC display helps confirm signal quality during setup.
After alignment, set the averaging mode through the menu buttons or RS-422. For instance, choose Fast, Medium, or Slow to balance speed and stability. Meanwhile, verify the heater supply if you work in cold storage. Finally, test the PNP output against the actual target position.
