PRODUCT DESCRIPTON
The ERDI LASER® LRF20VB is a compact 905nm DTOF laser sensor designed for drones, sweeping robots, and industrial robots. It delivers reliable and precise laser distance measurement even in challenging environments, combining high performance with low power consumption and flexible integration.
Key Advantage
-
High-Precision Ranging: Measures 0.05–20 m with ±5 cm accuracy at short distances and 1% at longer ranges, ensuring reliable performance in complex environments.
-
Fast Measurement Frequency: Supports up to 200 Hz with selectable rates (100/50/20/10/1 Hz) for responsive and real-time distance detection.
-
Compact & Lightweight Design: Dimensions 21×15×7.43 mm, weight 1.5 g, easy to integrate into drones and mobile platforms.
-
Robust & Flexible Integration: Excellent ambient light immunity (up to 60K Lux), UART/I²C interface, low power (<0.2 W), and customizable appearance, structure, and output protocol.
