Product overview
The Eyoung EY-4002B Laser Range Finder Module uses an eye-safe 1535nm erbium glass laser for distance measurement. It reaches 6000m on large targets, 4000m on vehicles measuring 2.3m × 4.6m, and 2500m on human targets measuring 0.5m × 1.7m. Its minimum range is 50m, with ranging accuracy of ±1m. Single measurements and 1Hz or 5Hz operation support different measurement tasks, while multiple target detection accommodates two targets. The module has an accuracy rate of ≥98% and a false alarm rate of ≤1%.
Measuring ≤56 × 50 × 30mm and weighing ≤80g, the module incorporates an RS232 serial interface and operates from a 12±2V supply. Standby consumption is ≤0.1W, with zero consumption when powered off. It operates from -40 to +60°C and withstands rain, snow, ice and mud. Communication port and lens colour options are available. Applications include gimbal camera integration for altitude measurement, obstacle detection and terrain mapping, alongside industrial equipment spacing, production quality control and vegetation measurement.
