Z3J series infrared induction blocking material tracking discharging electric eye for bag making machine

General Introduction

A photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to that when light is irradiated on certain substances, the electrons of the substance absorb the energy of photons and a corresponding electric effect occurs. According to the different phenomena of photoelectric effect, the photoelectric effect can be divided into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells.

Infrared switch operation steps

Fix the photoelectric switch so that the photoelectric switch is facing the object to be detected, and adjust the sensitivity knob to adjust the detection distance of the photoelectric switch. Adjust the sensitivity knob from low to high, then the detection distance can be increased from 0mm to that of this model's maximum detection distance.

Color mark operation steps

Fix them in accordance with the demands of the testing distance. Then according to the packing paper you use, refer to the GuidGrids ( for reference of light source choice ) to decide on the light source (take the green one as example), and then decide the bright mark sensors on or the dark one to meet your machine's need. Now you can adjust the sensitivity according to the following three steps ( take, as example, that the output mark sensors on is a bright one, the packing paper is of light color and the background is dark color).

First, move the packing paper, cast the light on the background outside the sign. Turn the sensitivity control counter clockwise till to the end, then turn it clockwise till the indicator light just turns red, and remember the position of the sensitivity control is turned to the 'High' position and the indicator light still does not turn red, then the 'High' position is Point A.

Second, move the packing paper again, and when you cast the light on the center of the sign, the indicator light will turn red. Then turn the knob counter clockwise slowly till the indicator lamp just goes out, and remember the sensitivity control is in the position fo Point B as shown in Picture 2.

After operating the above two steps correctly, you can then turn the sensitivity control to a position between Point A and Point B, that is, Position C as shown in Picture 3, and now the adjustment is finished. The longer the distance between Point A and B is, the higher the ratio of the chromatic aberration and stable the test will be. The distance must be at least one scale between Point A and Point B, otherwise the test will not be stable.
