1535nm Eye-safe Laser Rangefinder Module 3.2km SF-DYC3001A

The SF-DYC3001A Mini Laser Rangefinder is a compact, lightweight (≤58g), and eye-safe laser module designed for precise long-distance measurement. Operating at a 1535nm wavelength (invisible to the human eye), it delivers a range of up to 3200m with ±1m accuracy. Ideal for integration into drones, robotics, and industrial systems, it features low power consumption, rugged durability (-40°C to +60°C operation), and versatile communication via RS422/TTL interfaces.

Key Selling Points

  • Eye-Safe & Compact: 1535nm laser ensures safety compliance; ultra-small design (50mm×36.5mm×24mm) for easy integration.
  • High Precision: ±1m accuracy with 98%+ success rate.
  • Versatile Modes: Single-shot, 1Hz, or 5Hz measurement; first/last target differentiation.
  • Robust Performance: Operates in extreme temperatures (-40°C to +60°C) and harsh environments.
  • Low Power: 0.5W standby, 2W average consumption.

Electrical Interface

The host connects to the rangefinder via the ​DF52-10P-0.8C connector (host side) and ​DF52-10S-0.8H connector (rangefinder side) for cross-testing. The pin definitions for the rangefinder’s power supply and communication ports are listed in the followingTable (transmit/receive directions are relative to the rangefinder). The position of Pin 1 on the connector is shown in the following Figure.
