HESAI ETX Long Range Automotive Grade Wide View Lidar Sensor

The HESAI ETX is an automotive grade 120° ultra long range LiDAR designed for L3 autonomous driving, advanced ADAS, robotaxi, and high speed vehicle perception. It is built for front facing long distance detection where vehicles need more time to identify road hazards and react safely.

HESAI ETX is important for L3 autonomous driving because it provides ultra long range perception, high resolution point clouds, and a slim low profile form factor that can support roof or behind windshield integration. It is engineered for L3 and L4 autonomous driving applications.

HESAI ETX has a listed ranging capability of up to 400 m at 10 percent reflectivity. This makes it suitable for long distance highway perception, early object detection, and expanded safety margin in higher level autonomous driving systems.

HESAI ETX is positioned as a higher range and higher resolution sensor compared with AT128. It reaches up to 400 m at 10 percent reflectivity, approximately twice the ranging capability of AT128, while its 0.05° x 0.05° angular resolution provides significantly higher detail for object detection.

Small object detection matters because L3 and L4 vehicles must identify distant road hazards early, not only large vehicles. ETX can detect small objects, such as wooden blocks measuring 15 x 25 cm, at distances of up to 150 m, supporting safer high speed driving decisions.

Yes. HESAI ETX can be mounted behind the cabin windshield and features a reduced window height compared with earlier models, supporting more efficient in cabin LiDAR integration. This is important for automakers that want long range perception without large external sensor housings.

Photon Vector Technology is a proprietary technology used in HESAI ETX to extend ranging capability while maintaining Class 1 eye safety and reducing size and power consumption. This technology improves ranging performance while keeping the sensor compact and efficient.

HESAI ETX provides up to 5,600,000 points per second in single return mode. This high point rate supports dense 3D perception for long range ADAS and autonomous driving scenarios where distant vehicles, pedestrians, and road objects need to be detected clearly.

Yes. HESAI ETX supports automotive safety and compliance requirements, including Class 1 Eye Safety, ISO 26262 ASIL B Functional Safety Product Certification, ISO 21434 Cybersecurity Product Certification, and ISO 21448 compliant development process.

A team should choose HESAI ETX when it needs an automotive grade ultra long range LiDAR for L3 autonomous driving, L4 fleet development, robotaxi perception, highway ADAS, or behind windshield front sensing. It is most relevant when 400 m class detection, small object recognition, high point density, and compact low profile vehicle integration are key requirements.
