STL-27L 360° DTOF LIDAR Sensor (UART, 25m)

The STL-27L is a compact 360° dToF (direct Time-of-Flight) LIDAR sensor with a measuring range of 0.03–25 m. It delivers high-resolution point cloud data at an angular resolution of 0.167° with a scanning frequency of 10 Hz and measurement frequency of 21,600 Hz, making it well suited for robotic navigation, mapping, and obstacle avoidance.

The sensor features a coaxial brushless motor rated for up to 10,000 hours of operation, ambient light resistance up to 60 klux, and UART communication. The provided SDK supports both ROS1 and ROS2. The laser conforms to FDA Class 1 eye safety standards.
