DESCRIPTION
The LRF0612C eyesafe ranging module is developed based on our company's independently developed 1535nm erbium-glass laser. It is classified as a level I eye-safe product. The module utilizes monopulse ranging technology, allowing for a maximum range of up to 10km. It supports UART (TTL_3.3V) and RS422 interfaces, providing upper computer software with specified settings and communication protocols. Its advantages include stable operation, compact size, and lightweight design.
