About this product
The Hesai JT128 is the most compact 128-channel 360° 3D LiDAR built for robotics — a palm-sized sensor (Φ62.5 × H73 mm, 265 g) that delivers true hyper-hemispherical coverage with a 360° horizontal × 189° vertical field of view. Built on Hesai's automotive-grade chip platform (over a million Hesai sensors shipped), it delivers a clean, structured point cloud engineered for algorithm-friendly perception.
It outputs up to 1,152,000 points/s in single return (2,304,000 in dual return) at 0.4° × 0.74° resolution, ranging to 40 m at 10% reflectivity (60 m max) with ±3 cm accuracy (typical) and 2 cm ranging precision. Rated IP6K7, drawing 8.4 W typical with ultra-low <30 dB acoustic noise and a −20 to +65 °C operating range, the JT128 is purpose-built for service-robot navigation and obstacle avoidance, warehouse and logistics safety, 3D SLAM and localization, and mobile mapping.
