The L1 Series TTL Laser Distance Sensors use phase-shift laser ranging, a proven measurement principle for short- and medium-range applications requiring high accuracy and fast response. By continuously modulating the emitted laser beam and analyzing the phase difference of the reflected signal, the sensor calculates distance with millimeter-level precision.

Unlike enclosed industrial sensors, the L1 series is designed as a compact module, making it ideal for embedded systems, OEM products, and custom housings. The TTL UART interface enables direct connection to microcontrollers, single-board computers, and embedded controllers, minimizing system complexity.

The L1-40 is optimized for short-range precision tasks, while the L1-80 supports extended measurement distances when reflective targets are used. Both models provide stable performance, low power consumption, and flexible communication settings for system integration.
