The detection distance can be adjusted according to the requirements. The sensor has a detection _x000D_ _x000D_ The sensor has a long detection distance, little interference by visible light, cheap, easy to assemble, easy to use and other characteristics, can be widely used in robot obstacle avoidance, ( but this infrared sensor probe is not suitable for use in the natural light lighting environment, because the natural light contains infrared, the need to use infrared probe friends please pay attention to this problem, used in the absence of infrared environment is still possible ) _x000D_ _x000D_ Assembly line counting and many other automation products. _x000D_ _x000D_ Electrical characteristics: _x000D_ U:5VDC _x000D_ I:100mA _x000D_ Sn:3-50CM _x000D_ _x000D_ Size: _x000D_ _x000D_ Diameter:17MM _x000D_ Sensor Length:45MM _x000D_ Lead wire length:45CM _x000D_ _x000D_ Pin Description: brown line is positive blue line is negative black line signal _x000D_ _x000D_ Photoelectric sensor (photoelectric switch) NPN normally open sensor LED is open _x000D_ Model: E18-D80NK. _x000D_ _x000D_ _x000D_ Technical parameters of photoelectric switch E18. _x000D_ 1, the output current DC / SCR / relay Control output: 100mA / 5V power supply _x000D_ 2Consumption current DC
