E18-D80NK Infrared Obstacle Avoidance Photoelectric Sensor

Proximity Switch 3-80cm Detection Range Adjustable D80NK

After connecting the power, if there is no signal, fix a place to adjust the adjustable resistor, adjust until the light is on, first to the right or left, adjust until you can hear the potentiometer overshoot, in the opposite direction!

This is a set of emission and reception in one of the photoelectric sensor. The detection distance can be adjusted according to the requirements. The sensor has a detection

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 )

Assembly line counting and many other automation products.

Answers to frequently asked questions about sensors:

1, Q: This is a digital sensor or analog sensor?
A: This is a digital sensor, NPN normally open photoelectric switch; output state is 0,1, that is, the digital circuit in the low level and high level, the normal state output high level, detected target output low level.
2, Q: can be connected to the microcontroller IO port?
A: Can be directly connected to the microcontroller IO port to use.
3、Q：What is the resistance value of the pull-up resistor?
A: Plus pull resistance is generally about 10K;
4, Q: Why is the indicator light always on after connecting the power supply?
A: First of all, to ensure that the power supply is a stable 5V ± 2%, and secondly, the probe output can not be connected to the microcontroller output port;
5, Q: Why is the indicator light always on after connecting the infrared switching power supply?
A: 1, please check the power supply has not been connected to the reverse, that is, the infrared output to the power supply is positive; 2, please check the direction of the probe to detect the range of obstacles, good for the direction of the open.
6, Q: instructions for use, the introduction is too simple?
A: This is a photoelectric switch, there are only three lines, power, ground, output, do not need too complex introduction.
7, Q: infrared obstacle avoidance sensor is not NPN
A: Yes
