Grade VI of IP dust proof represents the full prevention from intruding by foreign object and
dust.
Grade V of IP dust water represents the prevention from damaging the electrical appliance by
the intrusion of water from the nozzle at different directions.
TF02 protection grade can ensure its normal operation under light rain, moderate rain,
pesticide spraying by drone and polluted optical windows.
If the operating environment is harsh, and you would like to know more about the impact of
optical window pollution, please contact us for TF02 Single-point Ranging LiDAR Pollution Test
Report.
5.2 Anti-pesticide corrosion
With special ratio and test, TF02 shell material is different from the traditional plastic material,
and more resistant to pesticide corrosion, so it can work normally in the harsh outdoor
environment. Especially in the field of plant protection drone, anti-pesticide corrosion can
greatly improve the product's reliability and life.
TF02 shell consists of two materials, as shown in the figure below. Material A and material B,
respectively, constitute its shell and optical window. The two materials will go through the
following pesticide corrosion test: the two materials were respectively and completely
submerged in nine pesticides diluted 100 times for at least 48 hours.
TF02 shell materials
TF02 shell material corrosion test results are shown in the following table, where material A
(shell) is completely free from pesticide corrosion and material B (optical window) is partially
corroded. As the pesticide concentration and contact area of test materials with pesticide under
our test conditions are higher or greater than those in normal environment, it has a high
anti-pesticide corrosion characteristic.
