Photoelectric sensors can generally be divided into through-beam photoelectric sensors, retro-reflective photoelectric switches, diffuse-reflective photoelectric switches, and slot-type photoelectric sensors. But no matter which type of sensor we need to carry out regular inspections and maintenance.

Photoelectric sensor installation considerations:

1. Consider the application environment and light resistance of the product, so that the product is placed in a suitable application environment so that the product can play the optimal characteristics. For example, some miniature photoelectric sensors specifically designed for built-in use in machines generally do not add special features to prevent the disturbance of light. So be sure to avoid installing it in an outdoor environment with strong light.

2. When installing the sensor, please install it on a smooth surface and make sure the photoelectric sensor can be kept on the same level.

3. When fastening the miniature photoelectric sensor with screws, please use M3 screws (to prevent the screws from slackening, please use spring washers).

4. Do not hit the detection part of the sensor with other objects. If the detection part is damaged, the characteristics will deteriorate.

5. The fastening strength varies depending on the model, so please read the precautions for each product.

6. After installation, please make sure that there is no loosening or shaking caused by vibration or shock before use.

7. Please do not exceed the voltage range when using the product to avoid breakage or burnout.

Daily maintenance of the photoelectric sensor:

1. detection of objects and proximity to the installation position of the sensor is not deviated, slack, skewed.

2. Wiring, wiring department has no slack, poor contact, and broken line 3.

3. Whether there is metal dust and other adhesion, accumulation; use temperature conditions, environmental conditions are not abnormal.

4. Whether there is any abnormality in the flashing of the set display light type.

If the inspection must be careful not to disassemble and repair on their own, corresponding to easy to find out the fault, can be connected to the portable detector to investigate the sensor action status, and then according to the situation to repair.

In order to make the photoelectric sensor operate stably for a long period of time, it should be checked regularly with the same contents as the general control equipment to keep it functioning for a long time. The photoelectric sensor can also be stocked, once the photoelectric sensor is found to have problems, we can replace it in time, and will not affect the use of the sensor.
