650nm Laser Distance Sensor 100m SF-NFSG20010

The ​SF-NFSG20010 Laser Distance Sensor​ is a cutting-edge phase-shift measurement device designed for industrial automation and precision applications. Utilizing a ​650nm Class 2 visible red laser​ and advanced phase-comparison technology, it achieves ​​±1mm accuracy​ even on natural surfaces without reflectors. Ideal for harsh environments, this sensor combines speed (20ms response time), reliability (IP68-rated aluminum housing), and versatility (RS232/RS422/4-20mA outputs) to meet diverse industrial demands.

Key Selling Points

  • Ultra-High Precision
    • ​±1mm accuracy​ on white surfaces, ​0.1mm resolution, and ​​±0.5mm repeatability​ ensure reliable data for critical processes.
    • Phase-shift technology​ outperforms standard TOF (time-of-flight) sensors in stability and noise resistance.
  • Dual Measurement Modes
    • 0.03–100m range on natural surfaces; extends to ​200m with reflectors​ (ideal for logistics or large-scale infrastructure).
  • Rugged & Adaptive Design
    • Operates in ​​-10°C to 50°C​ and withstands ​1200°C radiant heat​ (e.g., molten steel positioning in continuous casting).
    • IP68 protection​ and vibration-resistant construction for mining, metallurgy, and heavy machinery.
  • Plug-and-Play Integration
    • Programmable analog (4-20mA)​​ and ​digital outputs (RS232/RS422)​​ with ASCII protocol simplify PLC/SCADA connectivity.
    • 10–30Hz refresh rate​ and ​wireless remote control​ for flexible operation.
  • Cost-Effective Maintenance
    • Low power consumption (​<1.5W) and ​600g lightweight design​ reduce operational costs.

Applications

  • Industrial Automation: Thickness/width measurement of metal plates, coil diameter monitoring, robotic positioning.
  • Metallurgy: Molten steel tracking in continuous casting, ladle car positioning.
  • Bulk Material Handling: Level detection in silos, tanks, or conveyor systems.
  • Construction & Logistics: Crane collision avoidance, large-volume inventory management.
