1. Detection Accuracy. The higher the accuracy of a safety light grid, the greater its precision and safety performance, and the higher the price. However, when selecting, we only need the accuracy to meet the protection requirements. We choose a cost-effective and reliable safety light grid that fulfills the protective purpose. 2. Protection Range. The protection range of a safety light grid is the specific area size of the light curtain protection. Within the protected area of the light curtain, any object entering or blocking will trigger effective safety protection and an alarm. We determine the height and length of the machine equipment that needs protection to select the appropriate light grid model for accurate safety protection. 3. Interference Resistance. In environments with strong light, electromagnetic, and vibration interference, it is necessary to choose a light grid model with shock resistance and strong interference resistance to avoid inaccurate light or signal transmission errors due to interference issues. 4. Protection Grade. For installation environments requiring waterproof and dustproof, you can choose a safety light grid with a higher waterproof and dustproof grade. 5. Output Method. Selecting the appropriate output method based on the actual installation scenario is also a crucial factor in ensuring the stable operation of the safety light grid. That's all for the introduction of the principles of using safety light grids. If you have any further questions, feel free to consult our website, where we have professionals ready to explain.
