Note:
To ensure your safety, please follow the following rules:
1. This product is only for target detection. Do not use this
product protects the human body or body parts, etc.
2. This product may not be used as explosion-proof products.
Do not use this product in hazardous locations and/or
environments with potentially explosive gases.
3. The product is DC - powered sensor. Do not use AC power.
Otherwise, the product will explode or catch fire.
