Where to buy in Singapore
Automotive-grade sensing and compute is supplied to vehicle manufacturers under design-win programmes, in production volumes and with multi-year validation — it is not sold as individual units through resellers. Approach the manufacturer directly if you are specifying for a production programme.
We do not supply this product. It already has strong distribution in Singapore, and buying locally gets you local warranty and service that we could not match. We keep the page because the comparison is still useful.
Highlights
- ✓Automotive-grade with ISO 26262 ASIL-B certification
- ✓Proven volume deployment on production vehicles
- ✓High 1.5M+ points/sec resolution at long range
- ✓Compact hybrid solid-state design with high ingress protection
Overview
Overview
The Hesai AT128 is a hybrid solid-state LiDAR sensor designed specifically for automotive Advanced Driver Assistance Systems (ADAS) and autonomous driving applications. "Hybrid solid-state" refers to an architecture that uses mechanical scanning in one axis and solid-state beam steering in another, achieving a balance between wide field of view, high channel density, and the reliability demanded by series-production vehicles. Its 128 evenly distributed channels are arranged to cover a 120 × 25.4 degree field of view, making it well suited as a forward-facing sensor on production vehicles.
How It Works
The AT128 uses laser pulses and time-of-flight measurement to build dense three-dimensional point clouds of the surrounding environment. It operates in single-return mode at 1,536,000 points per second, with 0.1° horizontal and 0.2° vertical angular resolution, and a pixel resolution of 1200 × 128. At these resolutions, the sensor can distinguish fine spatial detail at distance — important for identifying pedestrians, vehicles, and road obstacles well ahead of the vehicle. The 210 m detection range is specified at 10% reflectivity, meaning the sensor can reliably detect low-reflectance objects such as dark clothing or worn road markings at that distance.
Automotive Readiness
The AT128 is built to meet the rigorous standards required for installation in consumer and commercial vehicles at scale:
- ISO 26262 ASIL-B functional safety product certification addresses systematic and random hardware faults in safety-relevant automotive systems.
- Class 1 eye safety ensures the laser emissions are safe under all foreseeable operating and exposure conditions.
- IP6K7 and IP6K9K ratings confirm full dust ingress protection and resistance to high-pressure, high-temperature water jets — conditions encountered in vehicle wash cycles and harsh weather.
These certifications are prerequisites for integration into OEM vehicle platforms, where regulatory and liability requirements demand verified safety documentation.
Real-World Deployment and Users
The AT128 has moved beyond the prototype and pilot phase into genuine volume production. It has been selected as the primary forward-facing LiDAR by multiple Chinese electric vehicle manufacturers for series-production models, and is also deployed in robotaxi fleets. This level of deployment means the sensor has been validated through the full automotive supply chain — including durability testing, manufacturing quality controls, and integration with vehicle compute platforms — rather than existing only as an engineering sample or low-volume unit.
