In actual working conditions, the damage or instability of the safety light curtain is often caused by unstable voltage, poor grounding, interference from ambient light, dust, and water ingress. Therefore, for some dusty and watery working environments, we need customized waterproof and dustproof safety light curtains. At the same time, in order to improve the trouble-free working time of safety light curtain products, it is recommended to consider the following factors when designing safety light curtains:

- IP65 degree of protection (waterproof and dustproof safety grating protection grade is IP67)

- Ambient light resistance to light intensity above 100000Lux

- Anti-light intensity of fluorescent lamps is more than 3000Lux

- Metal shell, grounding-free design

- Passed static discharge test of at least 4000V

- Can withstand 1000V instantaneous surge

- Can withstand group pulses above 4000V.
