DL50-P1123 SICK Dx50 Retro-Reflective Laser Distance Sensor
DL50-P1123 is a SICK Dx50 series retro-reflective laser distance sensor. It uses HDDM optical time-of-flight technology. This sensor measures up to 50 m on Diamond Grade reflective tape. Accuracy is ± 7 mm. Repeatability is ≥ 2 mm. It is built for heavy-duty industrial automation. The Class 1 laser is eye-safe. It needs no extra safety measures.

Oiltech Controls’s Insight
- The DL50-P1123 targets long-range jobs. It reads Diamond Grade tape at up to 50 m.
- Class 1 laser means no eye protection. This saves time on site.
- The 4 mA to 20 mA current loop resists noise over long cables. This suits plant floor wiring.
- HDDM optics hold steady under ambient light. Readings stay stable in bright halls.
- Zinc die-cast body handles vibration and impact. It fits crane, rail, and logistics gear.

Installation Notes
- Mount the sensor on a rigid bracket. Keep the beam square to the tape.
- Use the M12 5-pin connector. Check pinout before power up.
- Keep supply within DC 10 V to 30 V. Protect against short circuits.
- Add cooling plates above +65 °C. Add a filter above +80 °C.
- Clean the PMMA window with a soft cloth.
Commissioning and Care
- Use the LC display and menu buttons for setup.
- Pick fast 15 ms or slow 30 ms response by task.
- Scale the 4 mA to 20 mA output during startup.
- Check readings against a known target. Confirm repeatability.
- Inspect the window and connector each service cycle.

FAQ
Q: Does the DL50-P1123 need a reflector?
A: Yes. It works with Diamond Grade reflective tape. This gives the full 50 m range. For natural objects, choose a diffuse model instead.
Q: Is the laser safe for open areas?
A: Yes. It is Class 1 eye-safe. No extra guards or goggles are needed. This speeds up installation and service.
Q: Can it run on 12 V?
A: Yes. The supply range is DC 10 V to 30 V. It is reverse-polarity protected. Avoid short circuits above 8 A.
Q: How do I pick between the PNP and analog output?
A: Use PNP for simple on/off triggers. Use 4 mA to 20 mA for continuous distance data. Many users wire both.
Q: What if my old Dx50 unit is discontinued?
A: The DL50-P1123 fits many legacy mounts. Send us your old part number. We check pinout, range, and output type before you buy.
