Description
- Brand Name: NoEnName_Null
- Origin: CN(Origin)
- Usage: Ray Sensor
- Type: Optical-Electronics Sensor
Product composition: the laser head is composed of three parts: light emitting tube core, focusing lens and sleeve. When the laser head is sent to the user, the three parts have been assembled, the lens focal length has been adjusted and glued with strong glue, and the user can work after connecting with 4.5V DC power supply.
Product Description: in the ideal case (no dust, no smoke, no obstruction), the laser transmission distance is unlimited. The transmission distance of the laser head can reach more than 1km when the air quality is high and the working current is 20mA. It can be easily seen on objects 500 meters away on cloudy nights; For a closer distance, even in the daytime sun, it is clearly visible on the outdoor road and buildings
Working voltage: 4.5 V 51 resistor working time: very long (because there is no accurate test)
