1. There are 4 wires for the wiring sensor, among them, the red or brown wire is connected to the positive power supply, and the black wire is connected to the negative power supply; The green or blue wire is the dark output line, and the white or yellow wire is the bright output line, the user can choose one of them according to his needs, and the other is not used, but it should be insulated. Short-circuits or incorrect connections are not allowed on each line.
2. The sensor is installed vertically above the object to be detected. The sensor should have a distance of 5mm between the top and bottom of the sensor.
3. Sensitivity adjustment: First, adjust the upper and lower positions of the sensor to make the light spot clear; Then align the spot at the junction of the color scale and the base color, so that half of the spot falls on the color scale and the other half falls on the base color; Look at the indicator light, if the green light is on, the sensitivity knob will be adjusted in reverse direction to "-". When the two lights have just changed the indication state.
4. The width of the color code The width of the color code can be obtained by the following formula. Under normal circumstances, the width of the color code is required to be greater than 2mm. B》v×t+d wherein: B - color scale width, mm; v——color mark moving speed, m/s; t - total response time, ms; d——The size when it can be distinguished, mm.
5. The selection of the color code color is very serious, and the contrast with the background color is very large, so as to ensure the reliability of the detection.
6. The selection of the detection light source is mainly determined according to the color mark and background color.

Banner Sensors – How pressure sensors work
1. Piezoresistive pressure sensor
Resistive strain gauges are one of the main components of piezoresistive strain transducers. The working principle of metal resistance strain gauge is the phenomenon that the resistance value changes due to mechanical deformation due to the strain resistance adsorbed on the base material, which is commonly known as the resistance strain effect.
