2. Introduction

The Siman (西曼) SDFM Series is an ultra-compact, high-frequency industrial-grade laser distance ranging LiDAR sensor module designed for medium to long-range high-precision measurements. Covering measuring distances from 100 meters up to 1500 meters (@ 90% reflectivity), it operates on a 905nm Class 1 eye-safe laser with high-speed moving target tracking up to 10,000 Hz (10 kHz) sampling frequency. Featuring dual UART / I2C interfaces, 9–36V DC wide voltage input, and 100 kLux strong ambient light immunity, it is engineered for humanoid robotics, robotic arms, quadrupeds, AGVs, drones, and industrial distance monitoring.

3. Features

• Long Measurement Range: 100m (SDFM100), 200m (SDFM200), 300m (SDFM300), 600m (SDFM600), and 1500m (SDFM1500) optional range versions with blind zone as small as 0.05m.
• High-Frequency Tracking: 1 kHz default ranging frequency, adjustable from 20 Hz up to 10 kHz (10,000 Hz) for high-speed dynamic tracking.
• 100 kLux Strong Ambient Light Immunity: Reliable performance and high anti-interference in direct outdoor sunlight and harsh optical environments.
• Dual Communication Interfaces: Standard UART (3.3V TTL) and I2C / IIC digital interfaces for seamless secondary development.
• Wide Voltage Input & Low Power: Operates on 9–36 VDC with low power consumption (0.7W for SDFM100/200; 1.2W for SDFM300/600/1500).
• Ultra-Compact & Lightweight: Weighs only 20±2g with a miniature 33×34×18mm aluminum enclosure and 4-M2 mounting points.
