About AT128

AT128 is Hesai's forward-looking automotive LiDAR for high-resolution detection across a 120° by 25.4° field of view. Its 128 evenly distributed channels produce 1,536,000 single-return points per second with 0.1° horizontal and 0.2° vertical angular resolution. Hesai specifies 210 m ranging at 10 percent reflectivity and detection of vehicles and pedestrians at roughly 200 m.

The sensor measures 136 × 114 × 49 mm, weighs 940 g and consumes 13.5 W. IP6K7 and IP6K9K protection, Class 1 eye safety and ISO 26262 ASIL B product certification support integration into ADAS, robotaxi, robotruck and logistics platforms.
