Hesai Technology QT128 Auto-Grade 360° x 105° Short-Range Lidar
Auto-Grade 128-Channel 360° Ultra-Wide View Short-Range Lidar
Hesai's QT128 is a compact, high-performance 128-channel mechanical lidar sensor designed for autonomous vehicles, robotics, and smart infrastructure. With a 120° horizontal field of view and 25° vertical FOV, it delivers rich 3D perception in real time. QT128 outputs up to 3.46 million points per second in single-return and 6.91 million in dual-return mode. It offers ±3 cm ranging accuracy, a maximum range of 200 meters, and configurable horizontal resolution from 0.1° to 0.4°. QT128 supports advanced synchronization via PTP and operates reliably in harsh environments with an IP6K7/IP6K9K rating and a –40°C to 75°C temperature range. Its compact form factor makes it ideal for space-constrained applications requiring high-density point clouds and wide-angle coverage.
