Hesai Technology OT128 Auto-Grade 360° x 40° Long-Range Lidar
Auto-Grade Flagship 360° High-Performance Long-Range Lidar
Hesai's OT128 is a cutting-edge 128-channel mechanical lidar sensor designed for high-performance 3D perception in autonomous vehicles, robotics, smart infrastructure, and industrial systems. With a full 360° horizontal field of view and an extended vertical FOV of 40°, it delivers up to 6.91 million points per second in dual-return mode. OT128 offers configurable horizontal resolution (0.1°–0.4°), ±3 cm ranging accuracy, and a maximum range of 230 meters. Engineered for reliability in harsh conditions, it features IP6K7/IP6K9K protection, operates from –40°C to 75°C, and supports advanced synchronization via PTP. OT128 is ideal for applications requiring dense point clouds, wide-angle coverage, and robust data quality under demanding conditions.

Why Choose the OT128 Auto-Grade 360° x 40° Long-Range Lidar?
A single OT128 lidar can cover a vehicle’s entire field of view without stitching.
With a finest angular resolution of 0.1° (H) x 0.125° (V), the OT128 can accurately perceive objects large and small at a distance of 200 meters away, providing powerful perception data for autonomous driving systems.
Under 100 klux strong ambient light, OT128 has a ranging capability of 200 m at 10% reflectivity (230 m maximum), clearly detecting objects in real time and capturing every detail of its surrounding road conditions.
