The Hesai JT128 is the most compact 128-channel 360° 3D LiDAR built for robotics — a palm-sized sensor (Φ62.5 × H73 mm, under 250 g) that delivers true hyper-hemispherical coverage with a 360° horizontal × 189° vertical field of view. Built on Hesai's automotive-grade SiPM chip architecture (1M+ units shipped), it suppresses crosstalk in hardware for a clean, structured point cloud with no false filtering, and sustains 25 G mechanical shock without data loss.

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 and 1 cm precision in the 1–5 m sweet spot. Rated IP6K7, drawing 9.5 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.
