1535nm Eye-safe Laser Rangefinder Module 2.5km SF-DYC20B

The SF-DYC20B is a high-precision, ultra-compact laser rangefinder designed for seamless integration into advanced systems. Operating at an eye-safe 1535nm wavelength, it delivers rapid and accurate distance measurements up to 2,700m with ±1m precision. Ideal for both industrial and professional applications, its lightweight design (45g) and robust construction ensure reliability in harsh environments.

Key Selling Points

  • Compact & Lightweight: Φ34mm x 55mm, perfect for drones, robotics, and portable systems.
  • Eye-Safe Laser: Complies with international safety standards (1535nm wavelength).
  • High-Speed Measurement: Supports 1Hz–10Hz modes for dynamic scenarios.
  • Multi-Target Detection: First/last target priority and distance gating for clutter resistance.
  • Extreme Durability: Operates in -40°C to +60°C and withstands vibration/shock.
  • Low Power Consumption: 4.5–14V input with energy-efficient modes.

Key Features

  • Single/continuous measurement modes.
  • Built-in self-diagnostic and temperature compensation.
  • RS422/TTL communication for seamless integration.
  • Configurable distance gating (10–4,000m).

Applications

  • Industrial Automation: Robotics, AGV navigation.
  • Surveying & Construction: 3D mapping, structural monitoring.
  • Security & Defense: Perimeter surveillance, target tracking.
  • Drones/UAVs: Obstacle avoidance, terrain mapping.
  • Outdoor Sports: Enhanced rangefinders for golf/hunting.

Electrical Interface

The electrical interface requirements are as follows:
a) ​Power Supply Voltage: 4.5V–14V (5V typical);
b) The host connects to the rangefinder via an ​A1002H-10P connector (host side) and an ​A1002WR-S-10P connector (rangefinder side) for interconnection testing. The communication port pin definitions are listed in Table. ​RS422 and TTL communication cannot be used simultaneously.
