The Hesai QT128 is an automotive-grade, 128-channel, 360° mechanical short-range LiDAR engineered to eliminate near-field blind spots. Its 105.2° ultra-wide vertical field of view and 0.05 m minimum range keep vehicles, pedestrians and low obstacles clearly resolved right beside the sensor, with a 20 m ranging capability at 10% reflectivity (50 m instrumented range), ±3 cm typical accuracy and 2 cm precision. ISO 26262 ASIL B functional safety certification and accurate reflectivity output make it a dependable primary sensor for close-range perception.

With selectable 10/20 Hz frame rates, up to 1.73 million points per second in dual-return mode, and finest 0.4° horizontal and vertical resolution, the QT128 packs dense, uniform near-field coverage into a compact Φ87 × 83.9 mm housing. Rated IP6K7 & IP6K9K with a 940 nm Class 1 eye-safe laser, 12–24 V DC input, and automotive 1000BASE-T1 Ethernet across a -40 °C to +85 °C operating range, it is a proven blind-spot solution for autonomous-vehicle development, AGV/AMR and warehouse robotics, service robots, and near-field safety in intelligent transportation systems.
