TOF (Time-of-Flight) Ranging Technology
Adopting TOF (Time of Flight) ranging technology, this sensor measures distance based on the time-of-flight of laser pulses. It achieves a maximum ranging distance of 25m, meeting the demands of most commercial applications, and offers a measurement accuracy of ±20 mm within an effective detection distance of 8m. Its efficient algorithm logic enables 360° detection for robots, autonomous mapping, and obstacle detection.
Supports Start-stop Control via Software
With open-source demo, schematic diagrams, and other resources for the adapter board, the STL27L allows for personalized development and Lidar operation control, effectively prolonging its lifetime.
More Stable Performance, Long Lasting Lifetime
The STL27L incorporates a coaxial brushless motor, ensuring quiet operation without friction and supporting high-speed wireless data transmission with stable performance. It boasts a lifetime of 10000+ hours, meeting the requirement for low failure rates in projects.
360° Omni-Directional Laser Scanning
The ranging core rotates clockwise to perform 360-degree scanning and ranging of the surrounding environment, thereby acquiring a contour map and point cloud information of obstacle locations.
Ranging Radius up to 25m
With a longer ranging distance, the STL27L can obtain environmental information from a farther range, ensuring enhanced cruising and mapping capabilities for robots in large areas.
* The ranging distance data is obtained by repeated measurements of STL27L and a target surface with 80.6% reflectivity under laboratory conditions.
High Real-time & Accurate Map Building
Supports scanning at 10Hz and measuring distance at a rate of 21600Hz, effectively reducing navigation blind spots and improving scanning coverage.
Multi-echo Detection Technology, Supports Glass Wall Detection
Through multi-echo detection technology, the STL27L supports glass wall detection at specific angles, reducing collisions during robot operation and increasing safety.
Strong Ambient Light Tolerance
Utilizing excellent filtering technology, this sensor operates reliably in up to 60Klux strong light, making it suitable for a variety of indoor and outdoor scenarios.
Exquisite, Compact, Easier to integrate
Its compact structural design results in a smaller size and lower power consumption, allowing for easy embedding within robots to reduce overall size and improve maneuverability.
Laser Safety FDA Class 1
For human and pet safety, a low-power infrared laser emitter is used as the light source and driven by modulated pulses. The laser completes its emission in a very short period, complying with the FDA Class 1 human eye safety rating.
