Hesai Technology AT128 Auto-Grade 120° x 25.4° Long-Range Lidar
Auto-Grade 120° High-Resolution Long-Range Lidar
Hesai's AT128 is a high-resolution, automotive-grade solid-state lidar sensor optimized for series production of autonomous vehicles and advanced driver-assistance systems (ADAS). Featuring 128 channels, a wide 120° horizontal field of view, and 25° vertical FOV, it delivers up to 1.53 million points per second with superior point density and accuracy. With a maximum detection range of 200 meters (10% reflectivity), ±3 cm range accuracy, and 0.05° horizontal resolution, AT128 provides fine-detail perception for safe and reliable navigation. Its solid-state design ensures long-term durability, high vibration resistance, and compact integration into vehicle bodywork. Rated IP6K7/IP6K9K and operating from –40°C to 85°C, the AT128 meets the demands of real-world driving conditions while enabling true L3+ autonomy.
