650nm Laser Distance Sensor 100m SF-NFSG1003

The SF-NFSG1003 Laser Distance Sensor is an industrial-grade, high-precision measurement tool designed for demanding environments. Utilizing advanced ​phase-shift measurement technology, it achieves ±1mm accuracy even on natural solid surfaces without requiring reflectors. Ideal for applications ranging from manufacturing automation to heavy-duty industrial processes, this sensor combines reliability, durability, and cutting-edge performance.

Key Selling Points

  • Ultra-High Precision: Achieves ±1mm accuracy (on white surfaces) with 0.1mm resolution for critical measurements.
  • Wide Measurement Range: Covers 0.03m to 100m, suitable for both close-range and long-distance tasks.
  • Non-Contact & Versatile: Works on natural surfaces, including high-temperature objects up to ​1200°C​ (e.g., steel casting, molten metal).
  • Rugged Design: IP68-rated aluminum housing withstands harsh conditions (-10°C to 50°C operating temperature).
  • Fast & Efficient: 20ms response time and 5Hz sampling rate for real-time monitoring.
  • Easy Integration: RS232/RS422, 4-20mA analog output, and programmable digital I/O for seamless system integration.

Applications

  • Industrial Automation: Position control for containers, bulk solids, and liquid levels.
  • Metal & Steel Industry: High-temperature object detection (e.g., continuous casting, ladle tracking).
  • Material Measurement: Thickness, width, and diameter monitoring (coils, rolls, sheet materials).
  • Infrastructure & Logistics: Distance measurement for robotics, AGVs, and crane positioning.

Features & Workflow

  1. Phase-Shift Technology: Emits a 650nm red laser beam (Class 2, ≤1mW) and calculates distance via phase difference between emitted and reflected signals.
  2. User-Friendly Interface: TFT color display with wireless remote control for easy setup and monitoring.
  3. Programmable Outputs: Customize analog (4-20mA) and switch outputs for threshold alerts or process control.
  4. Low Power Consumption: <1.5W during operation, reducing energy costs.
