Possible effects of ultraviolet radiation on optocouplers

UV protection measures for optocoupler storage
Optocouplers are usually encapsulated in plastic, and ultraviolet radiation may have adverse effects on them. Ultraviolet radiation can decompose plastic molecular chains, leading to plastic aging; Change the color of plastic and affect its appearance; It may also cause the plastic to lose its elasticity and become prone to breakage, thereby affecting the physical structure and stability of the optocoupler, ultimately affecting its performance.
Specific protective measures
Selection of Packaging Materials
You can choose packaging materials with UV protection function to wrap the optocoupler. For example, adding ultraviolet absorbers to materials can absorb ultraviolet rays and reduce the radiation of ultraviolet rays on optocouplers, just like adding ultraviolet absorbers to protect plastics from the impact of ultraviolet rays during plastic manufacturing
Storage environment control
Avoid direct sunlight: Store the optocoupler in a place without direct sunlight, such as the internal area of the warehouse, and avoid placing it near windows or other places where direct sunlight is easily exposed.
Use a sunshade: If the optocoupler is stored on an open shelf, it can be covered with a sunshade, similar to covering plastic products with a sunshade to avoid direct sunlight exposure.
Control environmental conditions: Keep the storage environment dry, cool, and ventilated, and control the temperature and humidity within appropriate ranges. High temperature and high humidity may work together with ultraviolet radiation to accelerate the aging of optocoupler plastic packaging and other issues.
Identification and Management
Set up clear signs in the storage area of the optocoupler to remind staff that there are optocouplers that require UV protection stored in this area, and avoid exposing them to environments with UV radiation
