What Are The Main Factors Affecting The Use Of Photoelectric Guide Sensors?

The main factors affecting the use of photoelectric guide sensor are: 1. The difference of the detection medium: the influence of different medium on the photoelectric sensor is mainly due to the difference of the light reflectivity (light transmittance). Because of the different media, the materials are different, so the reflectivity is also different. The greater the difference in the reflectivity (light transmittance) of the medium, the higher the recognition rate of the sensor for different media under the same conditions, and the better the adaptability of the sensor.
Therefore, different sensors or different sensor circuit parameters should be selected for different light reflectivity (light transmittance) media. Different media have great differences in the reflectivity of light of different wavelengths. Therefore, when selecting a sensor, the wavelength of the sensor detection source should be considered, and whether the medium reflectivity corresponding to this wavelength can meet the requirements.

If the SG-2BC detects a source of infrared light with a wavelength of 940 nm, then black mark detection for thermal and thermal transfer printing will likely produce different results. Because the thermal sensitive material on the thermal paper reflects the infrared light strongly, the sensor may not recognize the black mark of the thermal print.

2. Different detection distances: The sensor has the best detection distance. Outside the optimal range of detection distances, the sensitivity of the sensor is greatly reduced and may not even work properly. The difference in detection distance is also reflected in the difference between the front end surface of the same sensor and the detected object. The front end surface of the sensor should be kept parallel with the object to be detected, so that the conversion efficiency of the sensor is the highest.

3, the environment: the impact of the environment on the photoelectric guiding sensor is mainly the natural infrared light, dust and other factors. The type of sensor we currently use is mainly diffuse type. When the transmitting tube emits a beam, the target produces diffuse reflection. The transmitter and receiver form a single standard component. When there is enough combined light to return to the receiver, the switch state occurs. Change, sensitive to dust and light conditions in the environment. Therefore, the impact of environmental factors should be fully considered when using.
