Its 360° × 189° hyper-hemispherical coverage collects surrounding floor, wall and overhead geometry, helping integrators capture interiors, corridors and other constrained spaces. The sensor supplies point-cloud measurements for mapping, architectural documentation and digital-twin workflows. A 0–60 m instrumented range, Ethernet connectivity and official SDK support provide the foundation for a custom scanning pipeline. JT64P is the LiDAR component; mapping software, motion estimation and the complete scanner are separate parts of the system. Features 64-channel Time-of-Flight sensing — Mechanical scanning provides three-dimensional distance and reflectivity measurements for spatial digitalization. Hyper-hemispherical spatial coverage — The 360° × 189° coverage is useful for capturing walls, floors, ceilings and architectural geometry from a compact sensor. Compact scanner integration — The approximately Ø62.5 × 73 mm housing suits handheld and space-constrained scanning designs. Close-range to room-scale capture — The specified instrumented range is 0–60 m; practical detection distance depends on the target and operating conditions. Selectable return modes — Single- and dual-return modes offer options for the point-cloud pipeline. Select the mode supported by the installed firmware and driver. 10 or 20 Hz scanning — Choose a frame rate to suit the motion and processing requirements of the scanning system. Ethernet data interface — 100Base-TX carries distance, azimuth and reflectivity data to compatible host software. Timing and software integration — GNSS/PTP timing options and official Hesai SDK and ROS drivers support integration with a larger sensing system. Specifications Technical values below follow the JT64P J09-en-260720 user manual unless otherwise stated. Match the manual and correction data to the delivered sensor and firmware.

Parameter Value Model / channels Hesai JT64P / 64 channels Sensing method Mechanical-rotation Time of Flight Instrumented range 0–60 m Ranging capability 20 m at 10% reflectivity, all channels; manual test conditions apply Typical ranging accuracy / precision ±3 cm / 2 cm; varies with range, temperature and target reflectivity Spatial coverage 360° × 189° hyper-hemispherical coverage, as described by Hesai Horizontal field of view 360° Angular resolution Horizontal: 0.4° at 10 Hz / 0.8° at 20 Hz; vertical: 1.5° average Frame rate 10 / 20 Hz Return modes Single: First, Strongest or Last. Dual: Last + Strongest, Last + First or First + Strongest Laser wavelength / class 905 nm / Class 1 Data interface 100Base-TX; distance, azimuth angle and reflectivity Clock sources GNSS / PTP; supported profiles are listed in the user manual Input voltage DC 9–32 V at the LiDAR connector Protection rating IP6K7 Ambient operating / storage temperature −20°C to +65°C / −40°C to +85°C Approximate size Ø62.5 × H73 mm; use the drawing for the delivered version The ranging-capability test uses normal incidence, 100 klx ambient illumination, detection probability above 70% and false-alarm rate below 10−4. Spatial coverage and the manual’s projected vertical angles describe different geometries. Point rate, power and mass must be checked against the applicable hardware and firmware revision. Applications Handheld Indoor Scanning Hesai’s application photograph shows JT64P integrated into a handheld scanning system. Broad spatial coverage supports capture while moving through rooms and corridors. The complete scanner pictured is an integration example and is not included with the LiDAR unit. Compact Spatial-Capture Systems The small cylindrical sensor can be integrated into portable data-capture equipment. Account for optical clearance, connector access, power delivery and heat dissipation when designing the enclosure. Architectural Documentation Collect spatial measurements of interior walls, ceilings, beams and columns as input to an as-built documentation workflow. Registration and dimensional checks depend on the complete scanning and processing system. Construction and Renovation Planning Use point-cloud capture to record existing spaces before planning changes. Select a mapping workflow that provides the accuracy and completeness required by the project. Industrial Facility Mapping Capture equipment areas, workspaces and constrained indoor routes for spatial records. Plan the sensor path around occlusions and evaluate reflective or transparent surfaces. Digital Twins and SLAM Research Supply point-cloud data to localization, registration and 3D reconstruction software. The LiDAR does not itself provide a finished SLAM map or a digital twin. Integration Notes Use the JT64P-specific pinout, mounting drawing and correction files. Maintain DC 9–32 V at the LiDAR connector; the user manual specifies an external supply capable of at least 2.6 A and 30 W. This is a supply-sizing requirement, not typical sensor power consumption. Keep the optical window clear and validate the point-cloud coordinate system, timestamps and calibration in the assembled scanner. Select a compatible SDK or ROS driver version before recording or processing data. Reference Documents Documents & Downloads JT64P User Manual — J09-en-260720 (PDF) JT64P Official Downloads Technical Background JT128 / JT64P Official Specification Page JT64P Spatial-Scanning Application Announcement SDK & Drivers Hesai LiDAR SDK 2.0 Hesai LiDAR ROS / ROS 2 Driver Packing List 1 x HESAI JT64P LiDAR Unit FAQ What is the JT64P designed for?JT64P is a 64-channel LiDAR for spatial digitalization, including handheld scanning, indoor mapping and architectural capture. It provides measurements for a host processing pipeline.Is a complete handheld scanner included?No. The packing list contains one JT64P LiDAR unit. The handheld-scanner photograph illustrates an integration example.How is JT64P different from JT128?JT64P has 64 channels and is positioned for spatial capture. JT128 has 128 channels. Range, point rate, correction data and software settings must be taken from the manual for the selected model.Is the full 60 m range available on every target?No. 60 m is the instrumented range. The J09-en-260720 manual specifies 20 m at 10% reflectivity for all channels under its stated conditions.Does the field of view mean 189° in a flat vertical plane?Hesai uses 360° × 189° to describe hyper-hemispherical spatial coverage. Projected vertical channel angles in the user manual use a different geometric definition. Use the matching channel-angle data when processing the point cloud.What point rate should my software expect?The J09-en-260720 manual lists 499,500 valid points/s in single-return mode and 999,000 in dual-return mode after reduced scanning near the zenith. Earlier product material cites a different rate, so confirm the installed firmware, return mode and applicable manual before sizing the pipeline.Does the launch article’s sub-centimetre figure guarantee map accuracy?No. The launch article describes relative precision in Hesai testing. The user manual separately specifies typical ranging accuracy of ±3 cm and precision of 2 cm. Complete-system mapping results depend on calibration, motion estimation and processing.Can I use ROS or ROS 2?The official Hesai SDK and ROS driver list JT64P support. Select the supported environment, dependencies and correction files for your installation.What power supply is required?Maintain DC 9–32 V at the sensor connector. The manual specifies an external supply capable of at least 2.6 A and 30 W. Follow its connector and wiring requirements.Does JT64P generate a SLAM map by itself?No. It supplies LiDAR measurements. A host computer, suitable localization or mapping software and system calibration are required to generate a map.
