Laser Module 5 V 2mm Rotary Encoder tabletop and other placesIntroduction : Device parts Length: 23mm Operating voltage: 4. 5 V 51 Resistance In the ideal case (no dust, no fumes, no barrier), the laser transmission distance is infinite. In general, cloudy night, exposure to 500 meters away from objects, it is clearly visible; For a closer distance, even in the sun of the day, shone on the pavement,outside the building,it is also clearly visible. Application: production of electronic pointer pens, electronic
