SICK DT50-N2123 Dx50 Hi Distance Sensor
The SICK DT50-N2123 is a high-performance optical distance sensor from the Dx50 Hi family. It uses HDDM time-of-flight technology to measure natural objects without a reflector. The DT50-N2123 reaches up to 13 m and delivers ≥ 1 mm repeatability. Its NPN digital output and 4-20 mA analog output fit many control systems. A zinc die-cast housing and IP65 rating support heavy-duty industrial use. Oiltech Controls ships this model in 24-28 hours by FedEx, UPS, or DHL, with a 12-month warranty.

Oiltech Controls’s Insight
- The DT50-N2123 suits long-range positioning where reflectors are hard to mount.
- Its 15 ms fast mode helps dynamic cranes and transfer cars.
- Slow mode at 80 ms averages noise on dark or shiny targets.
- NPN output works with many Asian and European PLC inputs.
- 16-bit analog feedback supports fine loop control.
- Zinc die-cast body resists vibration and impact.
- Cooling plates extend use near ovens, kilns, and foundry lines.
Oiltech Controls Review
- Repeatability of ≥ 1 mm is strong for a 13 m diffuse sensor.
- Class 1 laser needs no extra safety gear in most plants.
- LCD and menu buttons cut setup time on the floor.
- MF input adds teach and external control flexibility.
- IP65 housing handles dust and water spray.
- Good fit for retrofits where old sensors lack range or accuracy.

FAQ
Q: How far can the DT50-N2123 measure on dark targets?
A: It reaches 3,400 mm at 6% remission. For black rubber or dark steel, use slow mode and align the spot well.
Q: Can I use it outdoors?
A: Yes, but shield the receiver from direct sun. The IP65 housing handles rain and dust. Strong sunlight can still reduce stability.
Q: What cable and connector do I need?
A: Use an M12 5-pin cordset. Check pinout for NPN output, 4-20 mA, and MF input before power-on.
Q: How do I choose between DT50-P1123 and DT50-N2123?
A: Pick DT50-N2123 for longer range and NPN output. Pick DT50-P1123 for PNP output and 10 m range. Match the output to your PLC input type.
Q: Does it work in high-temperature areas?
A: Yes, with 2 cooling plates it runs to +80 °C. Add a protection filter for +140 °C at Uv ≤ 24 V. Keep airflow around the plates.
