Details

Built for robotics integration, the MVR2EB ToF laser ranging module combines a 0.3–20 m measuring range with UART/TTL serial communication and strong outdoor light resistance.



A compact 30 × 16 × 24 mm body, adjustable 10–200 Hz output, and a simple mounting method make integration easier for mobile robots and robotic arms.

Mechanical drawing helps confirm enclosure clearance, lens orientation, and the 2×M2 mounting points before installation.
