3km Range Finder Module features
1. Adopting self-developed 1535nm erbium glass laser, integrated structural design and multi-point sealing installation method on the front end face, strong anti misalignment ability, high durability, long working life, and eye safety;
2. Small field of view, non thermal receiving optical design technology, with good light noise suppression ability and wide temperature performance.
3. The internal interface of the circuit adopts a welding wire direct connection process, which is firm and reliable, and can avoid short circuits or poor contact caused by loose connectors, oxidation, and water vapor, improving product reliability and service life.

Electrical Interface
The cross linking test between the upper computer end and the DF52-10P-0.8C connector of the rangefinder end is realized through the DF52-10S-0.8H connector. The pin definition of the power supply and communication port of the rangefinder end is shown in the following table (receiving and sending relative to the rangefinder), and the position of the connector connection pin 1 is shown in the figure below.
