808nm-500 near-infrared laser module with adjustable focus 12V laser head high-power

Product Introduction Wavelength and power: 808nm Power 500 (m-w) Adjustable focus (i.e. adjusting the spot size) The power can be adjusted through an external PWM signal Working voltage: 12V Light class shape: non circular, it is a long linear light class Must read before buying: 1. The laser power module is relatively large, and eye contact is prohibited. Otherwise, permanent blindness may occur at your own risk! 2. Do not use in flammable and gas environment to avoid fire and explosion 3. Children are prohibited from coming into contact with this laser product 4. This laser is equipped with a power adapter that can be directly connected to the socket to emit light, because the infrared light eyes are basically Invisible, please be careful not to directly shine into your eyes. The light point can be clearly seen through your phone's camera 5. Do not open the module to prevent damage 7. PWM: 0-12V, frequency<18K 8. The laser interface has three pins. The red wire is connected to a 12V+power supply, the yellow wire is connected to a PWM+signal, the black wire is connected to a power supply GND, and the white wire is connected to a signal GND. The power supply and signal are grounded together! If you don't connect the signal directly to 12V+and GND, you can emit light! No need to connect the signal again, the signal is only used for controlling switches or adjusting power
