Frequently Asked Questions

What is the HESAI OT128 LiDAR used for?

The HESAI OT128 is an automotive grade flagship 360° high performance long range LiDAR designed for scalable autonomous driving, robotaxi, robotrucking, stationary applications, service robots, and industrial automation. It is built for systems that need full surround perception, long range detection, and high density point cloud output from a single spinning LiDAR sensor.

Why is it suitable for scalable autonomous driving?

A simplified transceiver module design reduces cost while maintaining high performance and reliability — relevant for autonomous vehicle programs that need 360° perception at scale instead of more complex multi sensor setups.

Is it a 360 degree LiDAR?

Yes. It offers a 360° horizontal and 40° vertical field of view with calibration free, unstitched 360° perception, meaning one sensor can cover a vehicle’s surrounding field of view without combining multiple LiDAR views.

What is the detection range of the HESAI OT128?

Listed ranging capability is 200 m at 10 percent reflectivity and 230 m maximum — long range 360° coverage for autonomous driving, L4 mobility, port logistics, heavy machinery, and industrial robotics where early object detection is important.

What makes it different from Pandar128?

It is positioned as a newer scalable 360° long range LiDAR with a simplified architecture and significantly reduced component count compared to previous generation products, enabling automated mass production and faster production cycles.

Why does the high point rate matter?

The sensor generates 3,456,000 points per second in single return mode and 6,912,000 in dual return mode. This density helps autonomous systems capture detailed 3D information from surrounding vehicles, pedestrians, road edges, infrastructure, and industrial environments.

How does it support all weather perception?

An Intelligent Point Cloud Engine (IPE) detects rain, fog, exhaust fumes, and water splashes at pixel level, filtering environmental noise and improving perception clarity in challenging road and outdoor operating conditions.

Is it suitable for industrial robotics and logistics automation?

Yes. It fits L4 autonomous driving, port logistics automation, industrial robotics, heavy machinery, and smart factory applications — especially outdoor automation and large scale industrial environments that require 360° long range perception.

Is it reliable for automotive and outdoor environments?

Yes. Validation covers UV aging, high temperature, IP6K7 and IP6K9K protection, mechanical shock, salt spray, thermal shock with water splash, low temperature wakeup, humid heat cyclic testing, vibration with thermal cycling, and electrical and electronic testing, alongside automotive grade reliability standards and extended operational lifetime.

When should a team choose the HESAI OT128?

Choose the OT128 when you need a scalable 128 channel 360° long range LiDAR for L4 autonomous driving, robotaxi, robotrucking, port logistics, industrial robotics, heavy machinery, or smart factory applications — most relevant when 360° unstitched perception, 200 m detection, high point density, all weather perception, and cost efficient scalability matter together.
