What are the inspection steps of the photoelectric sensor

The photoelectric sensor is generally composed of three parts: light source, optical path and photoelectric element. When the photoelectric sensor is working for a long time, we need to check it regularly. Photoelectric sensors can generally be divided into slot type photoelectric sensors, through-beam type photoelectric sensors, reflector type photoelectric switches, diffuse reflection type photoelectric switches. However, no matter what type of sensor we need to check regularly, the inspection steps are as follows: 1. Whether the detection object and the installation position of the proximity sensor are deviated, slack, or skewed; 2. Whether the wiring and connection parts are loose or have poor contact , Disconnection; 3. Whether there is adhesion or accumulation of metal dust, etc.; 4. Whether there is any abnormality in the operating temperature and environmental conditions; 5. Whether there is any abnormality in the flashing of the setting indicator lamp type.

We should not be able to disassemble and repair ourselves during the inspection, and the corresponding faults can be easily detected, and the sensor operation status can be investigated through the connection with the portable detector. In order for the photoelectric sensor to operate stably for a long period of time, the inspection of the same content as that of general control equipment should be performed regularly. Once there is a problem with the photoelectric sensor, we can replace it in time. -->Photoelectric sensor, generally composed of three parts: light source, optical path and photoelectric element.
