Optical sensor as one of the extremely important components of the speed gate, to ensure the normal use of the infrared sensor is the key factor to ensure the protection performance of the speed gate. So today I will take you to understand what are the precautions in the use of photoelectric sensors.

Precautions in the use of photoelectric sensors

1. Be sure to consider the application characteristics of the product and product parameters when installing the product. For some sensors with weak light resistance, only for the built-in use of the machine, be sure to do a good job of avoiding light treatment. Especially the DC light way sensors, such as in the incandescent lamp and other places where there is light interference use, do a good job to avoid light processing is very important.
 

2. Considering the working principle of photoelectric sensor, it is necessary to ensure that the product light transmitting and receiving behavior is carried out smoothly. Therefore, when installing the sensor, please do not install it in an uneven location.
 

3. When fastening the miniature photoelectric sensor with screws, please use the matching screws required by the manual. Do not use the screws because of the size of the problem caused by the loosening of the installation and damage to the phenomenon, these are easy to affect the effect of the use of photoelectric sensors.
 

4. The product needs to be protected from the impact of other objects during the use of the product. Miniature photoelectric sensor in the work needs to be fixed position to use, because the need to ensure stable reception of light signals. If the product body is violently hit, not only may form a fixed position misalignment, the phenomenon of line skew. It may also cause damage to the detection area and deteriorate the characteristics.
 

5. In the photoelectric sensor before use need to confirm that the product has no vibration, shock and other phenomena caused by loose, shaking situation. In this need to confirm two things. First, to determine whether the product is suitable for use in the current application environment. The second is to confirm whether there is a problem with the fixing of the product before use. Unstable installation, vibration and shock or loose or skewed in the installation can make the working condition of the sensor disturbed.
 

6. Check whether the power supply voltage connected to the sensor is in the range of power supply voltage used by the photoelectric sensor.
 

7. Dusty places will also cause interference to the photoelectric sensor. So make sure that the lens and body of the photoelectric sensor regularly to do cleaning treatment.
 

8. Corrosive gas more places or water, oil, chemicals directly splashed places may affect the use of photoelectric sensor effect.
 

9. Ensure that the product is used within the specified working temperature range.

Photoelectric sensor interference how to solve

1. When subjected to inverter interference: need to add an independent switch to the photoelectric sensor, separate power supply, to exclude power problems.
2. When subjected to light source interference: photoelectric sensor is mainly through the infrared beam to form a protective light curtain by the infrared beam, the designated protection area for safety protection, around if the use of strong light or the emergence of reflective light source, may affect the safety beam on the accurate transmission of light and signal, should try to avoid.

3. When subjected to position parallel interference: To prevent parallel interference of two or more sets of photoelectric sensors, you need to reasonably adjust the installation position of the machine or photoelectric sensors to avoid errors in the transmission or reception of the light beam.

4. When subject to external high-intensity signal interference: general protection photoelectric sensors should be used as far as possible from high-intensity signal interference sources.

In general, only in the daily operation of more attention to the photoelectric sensor clean, avoid the emergence of dust, oil and other pollution, away from the source of interference, regular maintenance, maintenance and inspection, in order to effectively avoid the photoelectric sensor interference problems.
