DL50-N1123 SICK Dx50 Retro-Reflective Distance Sensor
Brand: SICK · Model: DL50-N1123 · Series: Dx50 DL50 Standard
Part Number: 1047401
The DL50-N1123 measures up to 50 m on Diamond Grade reflective tape. It uses HDDM™ optical time-of-flight. The DL50-N1123 delivers ± 7 mm accuracy. The zinc die-cast housing survives heavy-duty automation. A 4–20 mA current output feeds long cable runs. The LC display and menu buttons simplify setup. This sensor fits standard Dx50 mounting brackets. It runs on DC 10–30 V with reverse-polarity protection.

Oiltech Controls’s Insight
The DL50-N1123 suits long-range retro-reflective jobs. Use Diamond Grade tape for full 50 m. For outdoor cranes, add the protection filter. For foundries, add two cooling plates. The 4–20 mA output beats voltage on long cables. Check reflector alignment first if readings drift. Keep spare tape on site.
FAQ
Q: Does the DL50-N1123 work without reflective tape?
A: No. It needs Diamond Grade tape for full 50 m range. Without tape, range drops sharply.
Q: Can I use it outdoors in direct sun?
A: Yes, but add the protection filter. Direct sun on the reflector can reduce stability.
Q: What cable length is safe for 4–20 mA?
A: The 4–20 mA output drives long cables. Stay under 300 Ω loop resistance for best results.
Q: How do I replace an obsolete Dx50 sensor?
A: Check the connector pinout first. The DL50-N1123 uses M12 5-pin. Many old Dx50 brackets fit directly.
Q: Which output should I pick for a PLC?
A: Use 4–20 mA for long runs. Use NPN for short runs or simple switching. The MF input adds trigger control.
