PRODUCT DESCRIPTON
The ERDI LASER® LRF100H is a 905nm high-frequency DTOF laser sensor designed for precision distance measurement up to 100 m. Ideal for robotics, industrial automation, and autonomous systems, it delivers reliable performance even in challenging ambient light conditions, supporting fast and accurate sensing for dynamic applications.
Key Advantage
- High-Precision Ranging: Measures 0.05–100 m with ±10 cm accuracy at short distances (<10 m) and 1% beyond 10 m, ensuring consistent reliability.
- High-Frequency Sensor: Supports 20 Hz to 10 kHz (default 1 kHz) for responsive real-time measurements in high-speed environments.
- Compact & Lightweight: Dimensions 33×34×18 mm, weight 20 g, suitable for integration into robotic and autonomous platforms.
- Robust & Flexible Integration: Excellent ambient light immunity (up to 100K Lux), UART/I²C interface, low power consumption (0.7 W), and customizable appearance, structure, and output protocols.
