About this product

SR18 is an 18-channel rotating LiDAR for mobile robot navigation, obstacle sensing and embedded robotics. It supplies 360° horizontal and 48° vertical coverage, RS485 point clouds and 200 Hz IMU data. The August 2026 manual describes mounting, GPS/1PPS synchronization and integration details, while the current product page and datasheet retain different voltage, power, blind-zone and temperature limits. These source-specific claims remain separate pending manufacturer clarification. Cover image: Manufacturer exact-model reference illustration.
